Every golf cart owner eventually wants to make a golf cart faster, and the upgrades that actually deliver results are more accessible than most people realize.
Your cart struggles up the hill behind your house. Acceleration feels sluggish pulling out of the driveway, even with a full charge.
Neighbors with similar carts somehow cruise past you on the same flat road.
Slow golf cart speeds affect more than convenience. Lost time adds up on large properties, and weak performance limits how you use the cart every day.
Three common problems cause most golf cart speed complaints:
- Aging batteries that deliver 60% to 70% of their original voltage under load, directly reducing motor output.
- Stock controllers are programmed with factory speed limits that restrict the motor well below its capability.
- Worn or undersized tires that increase rolling resistance and waste the power your motor does produce.
Carts & Parts has helped thousands of owners solve every one of those problems with the right parts and professional installation since 2007.
The following guide covers eight proven ways to make a golf cart faster, from simple maintenance fixes to full performance upgrades for both electric and gas models.
Key Takeaways
What is the fastest way to make a golf cart faster?
Upgrading the speed controller is the single most effective way to make a golf cart faster on electric models like the EZGO TXT, RXV, and Club Car Precedent. A higher amperage controller, such as a Navitas TSX or Alltrax AXE, unlocks more power from the existing motor and battery pack. Most stock controllers limit speed to 12 to 15 mph, while upgraded units can safely push 19 to 25 mph depending on the system configuration.
How much speed can new batteries add to a golf cart?
Switching from worn lead-acid batteries to a new 48V lithium battery pack can restore 3 to 5 mph of lost speed on electric golf carts. Fresh Trojan T-875 or T-1275 batteries deliver consistent voltage under load, while lithium packs from Samsung and RoyPow reduce weight by 150 to 200 pounds and maintain full power output through the entire charge cycle.
Do bigger tires really make a golf cart go faster?
Larger diameter tires increase top speed by covering more ground per wheel rotation on EZGO, Club Car, and Yamaha golf carts. Upgrading from stock 18-inch tires to 20 or 22-inch options can add 2 to 4 mph without any electrical modifications. Carts may need a lift kit for tire clearance, and acceleration can decrease slightly with larger tires due to increased rotational mass.
Are golf cart speed upgrades safe and legal?
The National Highway Traffic Safety Administration (NHTSA) classifies golf carts separately from low speed vehicles, with most communities capping speeds at 20 to 25 mph on public roads. Professional speed upgrades that include matching brake, suspension, and tire improvements maintain safe handling characteristics. An authorized EZGO dealer can ensure all modifications stay within manufacturer specifications and local regulations.
What Determines How Fast a Golf Cart Can Go?
EZGO, Club Car, and Yamaha golf carts leave the factory with speed limited to 12 to 15 mph for fleet use, but the same motors and electrical systems can safely deliver 19 to 25 mph with the right modifications.
Golf cart speed depends on a balance between electrical output and mechanical efficiency.
Understanding both sides helps you choose upgrades that work together rather than against each other.
How Does the Electrical System Affect Golf Cart Speed?
The battery pack supplies voltage, the controller regulates the current to the motor, and the motor converts that energy into wheel rotation.
A weak link in any part of that chain limits speed.
On a 48V electric EZGO RXV, the stock Curtis controller may limit the motor to only 275 amps.
An upgraded controller rated for 400 to 600 amps pushes significantly more power through the same motor, increasing both acceleration and top speed.
A complete overview of how these electrical components work together is available in our EZGO battery and electrical parts guide.
What Role Do Mechanical Components Play?
Tires, gear ratios, suspension alignment, and overall cart weight all affect how efficiently electrical power is translated into ground speed.
A cart carrying 200 extra pounds of worn lead-acid batteries has to work harder to maintain the same speed as one running a lighter lithium pack.
Worn bushings, under-inflated tires, and dragging brakes create friction that steals speed before it ever reaches the pavement.
Addressing mechanical drag often recovers 1 to 2 mph before any electrical components are touched.
Our complete EZGO golf cart parts guide covers every major system that affects performance.
How Do You Choose the Right Speed Upgrades for Your Golf Cart?
The right speed upgrade for an EZGO TXT running a 36V lead-acid system looks completely different from the best option for an RXV with 48V lithium batteries.
Cart model, age, current condition, and intended use all determine which modifications deliver the best results.
Starting with a professional evaluation prevents wasting money on upgrades your system cannot support.
A 400-amp controller paired with a worn-out motor and corroded battery cables will not perform as expected.
When Kaitlyn Filadelfo wanted upgrades done right, she found the process straightforward:
“We wanted to do some upgrades and from start until finished, the employees helped us every step of the way so we could make informed decisions. We were given a quote and there was no hidden fees whatsoever! They communicated with us as they were doing the upgrades and within a few days, they were dropping the cart back off to us! 10/10 recommend!”
With more than 1,550 five-star reviews, Carts & Parts has the track record to back up every recommendation.
Choosing the correct tire size for your golf cart is one example where professional guidance can save you time and money.
What Should You Do Before Upgrading Golf Cart Speed?
- Test your current battery voltage under load. A fully charged 48V pack should read 50 to 52 volts at rest and hold above 44 volts under acceleration. Anything lower signals battery replacement comes first.
- Check tire pressure and tread depth. Under-inflated tires by even 5 PSI below the recommended 18 to 22 PSI create measurable drag that slows your cart.
- Inspect brake cables and wheel bearings. Dragging brakes or rough bearings waste motor power and reduce top speed by 1 to 3 mph.
- Verify your controller model and amperage rating. Knowing whether you have a Curtis, Danaher, or Alltrax controller determines which upgrades are compatible.
How Does Upgrading Batteries Make a Golf Cart Faster?
Trojan T-875 deep-cycle batteries, Samsung SDI lithium packs, and RoyPow 48V lithium kits each deliver measurable speed improvements on electric golf carts, though through different mechanisms.
Worn lead-acid batteries sag under load.
A 48V pack that reads 50V at rest might drop to 38V during acceleration. The controller reads the low voltage and limits current to protect the system, thereby directly reducing speed and power.
Fresh lead-acid batteries restore full voltage delivery and can recover 2 to 3 mph of lost performance.
According to Trojan Battery Company, deep-cycle batteries should be replaced every 4 to 6 years, depending on maintenance and charge habits.
Lithium battery conversions deliver even greater speed gains. A 48V lithium pack weighs 150 to 200 pounds less than six 8-volt lead-acid batteries, and maintains consistent voltage from full charge down to 20% capacity.
Lead-acid batteries lose voltage progressively, meaning your cart runs slower as the charge drops. Lithium delivers the same speed on the first and last mile.
Our EZGO battery and electrical parts guide covers compatibility details for TXT, RXV, and Medalist models.
Professional installation ensures your charger, cables, and controller are all compatible with the new battery chemistry.
Trojan Battery provides detailed maintenance specifications on its website, trojanbattery.com.
Does a New Motor or Controller Make a Golf Cart Faster?
Alltrax AXE, Curtis 1268, and Navitas TSX controllers are the three most common upgrades that make an electric golf cart faster, each offering programmable OEM EZGO Golf Cart RXV Speed Controller Kit and torque settings that exceed factory limitations.
The stock controller on most electric golf carts caps motor output well below what the motor can handle.
Factory EZGO RXV controllers typically limit current to 275 amps.
An aftermarket controller rated for 400 to 600 amps delivers more power to the same motor, resulting in noticeably faster acceleration and a higher top speed.
Motor upgrades pair well with controller upgrades, but cost more.
A high-speed DC motor spins at higher RPM, increasing top-end speed. A high-torque motor improves acceleration and hill climbing instead.
Most owners get the best balance by upgrading the controller first and adding a motor later if needed.
The solenoid also matters in speed upgrades. A stock solenoid rated for lower amperage can overheat when paired with a higher-output controller.
Our EZGO golf cart solenoid guide explains how to match solenoid ratings to your controller amperage.
For owners considering speed limit adjustments on their existing controller, our golf cart speed limiter guide covers safe and legal approaches.
Brad Wilcox experienced how professional modifications make a real difference:
“Great service, very helpful and easy to work with. Done several modifications to my cart, and the work was great and fast. Highly recommended!!”
How Fast Does a 48 Volt Golf Cart Go?
A stock 48-volt EZGO TXT or RXV electric golf cart typically reaches 12 to 15 mph from the factory, while upgraded 48V systems with aftermarket controllers and fresh batteries can achieve 19 to 25 mph depending on the configuration.
Voltage alone does not determine speed.
The controller amperage, motor RPM rating, tire size, and total cart weight all influence the final number.
A 48V system with a worn battery pack and stock controller will be slower than a well-maintained 36V system running an upgraded speed motor.
The EZGO speed sensor and OEM EZGO Speed Sensor Harness- 2005-2019 PDS II Models- PN# 73327G02 (SKU 73327G02) play a critical role in how the controller manages power delivery.
A failing speed sensor kit can cause erratic speed readings and limit acceleration even with upgraded components.
Our EZGO speed sensor guide covers diagnosis and replacement.
Will Bigger Tires Make a Golf Cart Faster?
Upgrading from stock 18-inch tires to 20, 22, or 23-inch options on an EZGO, Club Car, or Yamaha golf cart can add 2 to 4 mph of top speed without any electrical modifications.
Larger tires cover more ground per rotation.
A 22-inch tire travels approximately 22% farther per revolution than a stock 18-inch tire, translating directly into higher ground speed at the same motor RPM.
The math is straightforward, and the results are consistent across all golf cart brands.
The trade-off is acceleration.
Larger, heavier tires require more torque to get moving, which can make the cart feel slower off the line.
Hills become harder, too. Owners who drive on flat terrain benefit the most from tire upgrades alone.
Carts with tires larger than 20 inches generally need a lift kit to prevent rubbing on the fender or body.
Our golf cart tire size guide covers exact fitment for each model year and helps you determine whether a lift is required.
Does Upgrading the Controller Make a Golf Cart Faster?
A programmable Navitas TSX, Alltrax AXE, or Curtis 1510 controller upgrade is the most impactful single modification for making an electric golf cart faster, often adding 3 to 7 mph depending on the existing system.
Stock controllers are intentionally conservative.
Manufacturers program them for fleet use on golf courses, where a target speed of 12 to 15 mph is set.
Aftermarket controllers allow owners to adjust maximum speed, acceleration curves, and regenerative braking settings to match their actual driving conditions.
Matching the controller to the motor and battery system is critical. A 600-amp controller paired with a 300-amp motor generates unnecessary heat and could cause damage.
Professional installation ensures that every component in the power chain can safely handle the increased output.
How Do You Make a Gas Golf Cart Go Faster?
Kawasaki-powered EZGO gas carts, Club Car Subaru engines, and Yamaha gas models respond to different speed modifications than electric carts, focusing on airflow, fuel delivery, and mechanical tuning rather than electrical upgrades.
Governor adjustment is the simplest starting point for gas carts. The governor limits engine RPM to control top speed, and small adjustments can add 2 to 5 mph without any parts replacement.
Larger gains require a high-flow air filter, performance exhaust, and carburetor tuning to improve the engine’s breathing efficiency.
Clutch upgrades make a significant difference on gas carts.
A Team clutch kit optimizes the torque-to-speed ratio, improving both acceleration and top end.
Our EZGO engine and fuel parts guide covers clutch, carburetor, and exhaust options for Kawasaki 13.5-HP engines.
Regular maintenance matters more for gas cart speed than most owners realize.
Dirty spark plugs, clogged air filters, and old drive belts collectively reduce power output by 10% to 15%.
A basic tune-up often recovers noticeable speed before any performance parts are needed.
Our gas vs. electric golf cart comparison breaks down the performance differences between the two.
What Happens When You Skip Proper Speed Upgrades?
Ignoring the right upgrade sequence or using mismatched components creates EZGO forward-reverse switch problems that cost more to fix than doing the job correctly from the start.
- Overloaded controllers overheat and fail. A stock solenoid paired with a high-amp aftermarket controller can melt contacts, leaving you stranded with a cart that will not move at all.
- Mismatched batteries damage the entire electrical system. Mixing old and new batteries in a series-wired pack causes the weakest cell to drag down the others, reducing speed and shortening the lifespan of every battery. The Consumer Product Safety Commission at cpsc.gov tracks golf cart incidents, and electrical failures from improper modifications appear regularly in their reports.
- Larger tires without matching brake upgrades compromise stopping distance. Higher speeds require proportionally more braking force, and stock drum brakes on most golf carts are not designed for sustained speeds above 15 mph.
- Skipping professional installation voids your warranty. Manufacturer warranties on EZGO, Club Car, and Yamaha carts specifically exclude damage caused by unauthorized modifications.
What Does a Properly Upgraded Golf Cart Look Like?
A well-planned speed upgrade delivers performance improvements you feel immediately, without sacrificing reliability or safety.
- Consistent speed from start to finish. Lithium battery upgrades eliminate the gradual slowdown that lead-acid carts experience as the charge drops below 50%.
- Smooth, responsive acceleration. A matched controller and motor combination delivers power progressively rather than the jerky, all-or-nothing feel of a worn stock system.
- Reliable performance over thousands of miles. Professional installations with OEM-quality parts from an authorized dealer last years, not months.
- Confidence on hills and with passengers. Proper torque and speed balance means your cart handles real-world conditions, not just flat pavement with one rider.
Scott Lasater saw exactly what a comprehensive upgrade delivers:
“The people at Carts & Parts converted our cart to a lithium battery, installed a lift along with a few other convenience upgrades. Their workmanship and quality was excellent. I would recommend them if I was in the market for upgrades or a new cart.”

Frequently Asked Questions About Golf Cart Speed Upgrades
How much does it cost to make a golf cart faster?
Speed upgrade costs vary based on the approach. Larger tires run the least, while a full lithium battery conversion with a new controller represents the highest tier. We recommend calling (937) 459-8891 for a quote specific to your cart model and goals.
Can you make a 36 volt golf cart faster?
36V EZGO and Club Car models can be upgraded with a high-speed motor, aftermarket controller, and larger tires. Converting from 36V to 48V provides the most significant speed increase but requires replacing batteries, the controller, the motor, and all wiring.
Will making my golf cart faster void the warranty?
Modifications performed outside manufacturer specifications can void warranty coverage on EZGO, Club Car, and Yamaha carts. An authorized dealer like Carts & Parts uses OEM-compatible parts and follows manufacturer installation guidelines to protect your coverage.
How fast can a golf cart realistically go after upgrades?
Most electric golf carts can safely reach 19 to 25 mph with proper upgrades. Exceeding 25 mph requires significant structural and braking modifications and may reclassify your cart as a low-speed vehicle under NHTSA regulations.
Should I upgrade the motor or controller first?
The controller upgrade comes first for most electric carts. A new controller unlocks more of the existing motor’s capability at a lower cost. If the motor is already maxed out after a controller upgrade, a motor swap then delivers the next level of performance.
How long do golf cart speed upgrades take to install?
Most single-component upgrades like a controller swap or battery replacement take 2 to 4 hours of professional shop time. A full performance build with batteries, controller, motor, and tires typically requires 1 to 2 days.
Are lithium batteries worth it for golf cart speed?
Lithium battery packs deliver consistent voltage throughout the entire discharge cycle, weigh 150 to 200 pounds less than lead-acid, and last 3 to 5 times longer. The higher initial cost pays back through faster speeds, longer range, and zero maintenance over the battery’s lifespan.
Can Carts & Parts ship speed upgrade parts to my location?
Carts & Parts ships OEM EZGO parts and performance components nationwide with free shipping on orders over $50. We also provide phone support at (937) 459-8891 to help you identify the right parts for your specific cart model and year.
I would like to change gears I’m also was going to go to 48 volt but I’m already getting 18-20 mph depending on were you are it’s a 36 volt I would like it to go 35-30 mph any suggestions would be appreciated
Hi there! Before offering suggestions to increase your golf cart’s speed from 18-20 mph to 30-35 mph while keeping your 36-volt system, it’s important to consider safety factors, as most golf carts aren’t designed for such high speeds.
Given that, here are some options to consider:
1. High-speed motor upgrade: Replace your current motor with a higher RPM motor designed for 36V systems
2. Controller upgrade: Install a more powerful controller that can handle increased current flow
3. Different gear ratio: Modify your rear end gear ratio for higher top speeds
However, please note:
– These modifications may affect your cart’s warranty
– You’ll need to upgrade your brakes to safely handle higher speeds
– Consider reinforcing your suspension system
– Make sure your tires are rated for these speeds
Also, be sure to check your local regulations regarding modified golf cart speeds, as there may be legal limitations for street use.

I have 2012 Ez-go-golf cart with a 13 horsepower Kawasaki engine what’s the best gear I can put on my cart for a better top speed. what is the cheapest way that I can do it myself and about how much would it cost a rough guess.
Hi Steven,
For your 2012 E-Z-GO golf cart with a 13 horsepower Kawasaki engine, the best gear upgrade for increasing top speed would be a 6:1 ratio gear set. This is the fastest gear set available for most golf carts and can significantly increase your top speed.
.
To do this upgrade yourself, you’ll need to purchase a high-speed gear set. The cost for the gears alone is typically around $150-$2002. However, keep in mind that installing these gears requires some mechanical knowledge and specialized tools.
Let us know if you have any more questions.
can I disconnect my speed limiter on a 96 ezgo txt? Or can I adjust it to go faster?
Yes, you can potentially adjust or modify the speed limiter on your cart, but there are some important considerations:
For a 1996 EZGO TXT, the speed limiter is likely controlled through the controller settings. You have a few options:
1. Check if your cart has an adjustable speed controller – some models allow for speed adjustment without complete removal
2. Consider a controller upgrade which can increase your top speed significantly
3. Consult with a professional golf cart technician who can safely modify your specific model
Before making any modifications, please remember that:
> Speed limiters exist for safety reasons
> Modifications may void warranties
> Local regulations may restrict modified golf carts
> Higher speeds require appropriate tires and braking systems
If you’d like specific instructions for your 1996 model, we recommend consulting your owner’s manual or reaching out to a certified EZGO technician who can guide you through safe modification options for your particular cart.
Hope this helps with your speed upgrade project!
We have a 2013 Star Ev Electric 6 seated custom cart with a 8.5” lift on 24×8.00-12 JOURNEY SS (super chunky) mini monster truck tires. Completely blacked out with black diamond plate flooring throughout . Model number STAR-48L-4SF-H with a 48V-200AH Lead Acid battery that we paid 17 grand for 👍🏾 THAT ONLY GOES LIKE 10 mph 👀 🙅🏾♀️👎🏾👎🏾👎🏾💆🏾♀️
Please help! I have 2 questions…is there a way to convert it from electric to gas powered? If not, how can I get it to push at least 25mph?
Sincerely,
Frustrated Toni
Hi Toni,
Thank you for reaching out—and we totally understand your frustration! Let’s break down each of your questions and outline practical solutions for your 2013 Star EV electric 6-seater with its lifted, heavy-duty build.
1. Converting to Gas:
Switching an electric cart like yours to gas is technically possible, but honestly, it’s a huge and expensive project. You’d have to replace just about everything, and it rarely ends up working well. In most cases, it’s better (and cheaper) to upgrade what you have.
2. Making It Faster:
With your big tires, lift kit, and seating for six, your cart is definitely working hard! Here are the best ways to boost your speed:
> Upgrade the motor and speed controller: A higher-powered motor and a better controller can make a huge difference. This is the #1 way to get more speed.
> Switch to lithium batteries: Lighter batteries can give you more pep and better speed, especially with a big cart.
> Tire/gearing tweaks: Giant tires look awesome but make the cart work harder. If you’re open to it, swapping to lighter tires or adjusting the gearing could help.
> General tune-up: Make sure your batteries and connections are clean and in top shape.
With these upgrades, 25 mph is definitely within reach! However, It’s important to keep in mind that wth big lifts, chunky tires, and higher speeds, stability can become an issue. Make sure your brakes and suspension are up to the task!
Any more questions, just give us a call at (937) 459-8891. We can talk it through with you and are here to help.
I have a 2021 yamaha fuel injection golf cart. Its lifted 6” with 23×10-12 wheels. It goes 28mph but doesn’t have too much torque. Any possible way besides gears?
Hi Chad,
Great question! Your 6″ lift and 23″ tires are definitely affecting your torque. Those larger wheels effectively act like taller gearing. Since you want to avoid changing gears, here are some alternatives for your 2021 Yamaha fuel-injected cart:
> ECU/Controller Programming : Many newer Yamaha carts can benefit from performance tuning. Companies like Navitas offer programmable controllers that can adjust torque curves and power delivery.
> High-Performance Air Filter: A less restrictive air intake can help your fuel-injected engine breathe better, providing modest torque improvements.
> Weight Reduction: Remove unnecessary accessories or switch to lighter wheels if possible. Less rotational mass means better acceleration.
> Tire Pressure Adjustment: Running slightly lower pressure (within safe limits) can improve traction and the feeling of torque off the line.
> Clutch Upgrade (if applicable): Some Yamaha models benefit from performance clutch kits that engage more aggressively.
The reality is that with 23″ tires, you’ve significantly changed your final drive ratio. While these suggestions can help, a gear change (higher numerical ratio) would provide the most dramatic torque improvement. Many owners with lifts and larger tires find a 6:1 or higher gear set transforms the driving experience.
Every setup is a little different, so the best combination depends on how you mainly use your cart. If you’d like, give us a call at (937) 459-8891. We ship nationwide and can walk you through the parts and upgrades that will get you the extra torque you’re looking for.
