How To Remove Speed Limiter On Electric Golf Cart

If you’ve ever wished your electric golf cart could go faster — whether it’s to efficiently navigate a larger course, keep up with a group of peers, or simply to enjoy a If you’ve ever wished you could go faster on your electric golf cart – whether it’s to efficiently navigate a larger course to keep up with your peers or simply to enjoy a faster ride – then removing the speed limiter may be an option you’ve considered. But before you do, it’s important to understand why speed limiters exist, the steps to safely remove them, and the potential risks.

Why Do Golf Carts Have Speed Limiters?

Speed limiters are not redundant, but are important in several ways to ensure the safe and stable operation of golf carts.

First of all, it is a safety feature. Golf carts are designed to run at low speeds, with relatively lightweight frames, basic braking systems, and suspensions without complex structural supports. Under such a premise, high speed driving will significantly increase the risk of accidents, especially in the golf course such as the existence of steep slopes, sharp curves in the terrain, the risk factor is even higher.

Second is regulatory compliance. Many regional laws and regulations clearly limit the speed of golf carts on public roads, sidewalks, and other areas, usually between 10-15 mph. The presence of a speed limiter ensures that the vehicle complies with these regulations and prevents the user from breaking the law.

Furthermore, from an energy efficiency standpoint, limiting speeds helps to extend battery life, allowing the cart to travel longer distances between charges, whereas high speeds can cause the battery to deplete quickly, significantly shortening range.

Finally, considering the terrain, golf courses, neighborhoods, and other common scenarios where golf carts are used often have obstacles such as pedestrians, trees, and water hazards, making high speeds dangerous for collisions.

7 Steps To Remove An Electric Golf Cart Speed Limiter

Tools And Materials Needed For Speed Limiter Removal

Before you start the operation, you have to prepare the right tools, which is the foundation to ensure the operation is safe and smooth. Tools needed include a one- and Phillips screwdriver, wrench set, flashlight, voltmeter, and a small container (to store removed screws, parts, etc. to prevent loss). If you are not sure of the details of the model of your golf cart, it is best to consult a professional, who is usually equipped with specialized tools for different models that can improve the precision of the operation.

Locate The Speed Limiter

The speed limiter is usually located near the motor or inside the control system of the golf cart. The first step is to turn off the power to the golf cart and disconnect the battery, completely cutting off the circuit to avoid electrical shock. Then check near the motor, such as on the underside of the golf cart or under the seat, and also look inside the control panel, usually behind the steering wheel or dashboard. For specific models such as E-Z-GO, Club Car, etc., be sure to refer to the owner’s manual to determine the exact location, as some speed limiters may be hidden behind panels or wiring harnesses. Use a flashlight to illuminate the small part when operating to ensure it can be clearly seen and avoid missing it.

Access The Control Panel

The speed limiter is usually integrated into the control panel of the golf cart and this panel is responsible for regulating the flow of power to the motor. To open the control panel, the covering panel or housing around it needs to be removed, which may require unscrewing bolts or loosening clips. All screws, bolts and small parts removed should be placed in a prepared container for subsequent reassembly. Afterward, double-check with a flashlight to make sure there are no hidden screws or fasteners that have not been removed.

Adjust The Speed Limiter Setting

After locating the speed limiter, adjust it according to the design of the golf cart. For some models, such as the Club Car, the speed limiter may be a screw or knob that controls the maximum speed and can be simply loosened or adjusted to raise the upper speed limit, while some other golf carts may have physical speed-limiting components such as resistors, sensors, and so on, which can be removed altogether. Be careful, however, to make sure you don’t over-adjust it or you may damage the motor, battery, or control system; refer to the manual for safe adjustment ranges.

Test Drive The Cart

After adjusting the speed limiter, reconnect the battery and take a test drive in a safe, open area, such as an empty parking lot. Gradually increase the speed during the test drive to check if the acceleration is smooth and the cart responds normally. At the same time, test the performance of the braking system at the new speed to make sure the brakes can cope with the faster speed, as poor braking is a major safety hazard. If the golf cart feels unstable or accelerates poorly, stop immediately and readjust the speed limiter.

Fine-Tune and Calibrate the Speed Settings

If the test drive reveals that the golf cart is too fast, difficult to control, or accelerates unevenly, make small adjustments to the speed limiter. Make adjustments gradually, such as 1/4 turn of a screw or knob at a time, and retest after each adjustment. The emphasis is on balancing speed and stability to achieve a faster riding experience while ensuring safe operation.

Reassemble And Final Check

When satisfied with speed and performance, reassemble all panels, screws and bolts in the reverse order of disassembly, making sure they are tight, as loose parts can make noise or cause damage during use. Then perform a final check for loose or damaged wiring connections, battery terminals and control panel components. Finally, take another test drive to make sure everything is working properly.

Potential Risks And Downsides Of Removing The Speed Limiter

Safety Concerns

The golf cart’s braking system, suspension and frame are designed for low speeds, and high speeds are beyond the structural tolerance of the golf cart when the speed limiter is removed. In sharp turns, downhill or uneven terrain, the vehicle is prone to rollover and brake failure, significantly increasing the risk of collision or injury.

Legal Issues

Most jurisdictions have clear legal limits on the speed at which golf carts can be driven, especially in areas such as public roads, neighborhoods or parks. Removing the speed limiter and exceeding the speed limit may result in fines, Vehicle seizure, and even insurance claims.

Warranty Implications

Almost all golf cart manufacturer’s warranties list “unauthorized modification of the speed limiter” as an exclusion. In the event of damage to the motor, battery or control system due to the removal of the speed limiter, the manufacturer will deny warranty service and the cost of repairs will be borne entirely by the golf cart manufacturer.

Battery Life and Motor Wear

Driving at high speeds will cause the battery to discharge faster, shortening the range by 30%-50%, and significantly reducing the battery’s cycle life, requiring more frequent replacement. At the same time, core components such as the motor and gearbox are overloaded for a long period of time, resulting in increased wear and tear, higher failure rates, and increased maintenance costs.

Vehicle Stability and Handling Decrease

The factory-designed center of gravity and steering system are matched with low-speed driving, and are prone to problems such as “fluttering” and “sluggish steering” after speeding up, especially on windy or slippery roads, where the vehicle is difficult to control, which further magnifies the safety risk.

Alternative Ways To Increase Golf Cart Speed Without Removing The Limiter

Upgrade To A High-Performance Motor

The motor is the core power source of the golf cart, and the original motor is usually designed for low speed with limited horsepower. Replacing it with a higher-horsepower, high-performance motor can speed up your ride by directly increasing the power output without changing the speed limiter. The advantage of this method is that there is no need to change the vehicle’s speed limiter system, and the speed increase can be achieved by optimizing the power core only, and it is highly adaptable and can be retrofitted to most vehicle models.

Use High-Performance Tires

The performance of tires directly affects the efficiency of the vehicle. Choosing high performance tires with a low profile and wide tread reduces rolling resistance while driving, allowing the car to overcome ground friction more easily, thus increasing speed. Designed for high speeds, these tires provide a more stable grip without altering the vehicle’s structure or circuitry, ensuring safety and compliance.

Upgrade The Golf Cart Batteries

The power output of the battery is a key factor in the speed of the motor. If the original battery voltage is low (e.g. 36V), you can upgrade to a higher voltage battery (e.g. 48V), or increase the number of batteries if the vehicle’s load capacity permits, in order to improve the overall power output. More energy supply allows the motor to run more powerfully, which naturally leads to higher speeds. In addition, replacing traditional lead-acid batteries with lithium-ion batteries reduces the weight of the vehicle and indirectly improves driving efficiency.

Lighten The Golf Cart’s Weight

The weight of a vehicle is inversely proportional to its speed. The lighter the weight, the less resistance there is when accelerating and traveling. Weight can be reduced by removing unnecessary items from the cart or by replacing heavy components (e.g., replacing a steel frame with an aluminum frame, replacing a conventional seat with a lightweight seat). This approach requires no changes to the power train, and speed increases can be achieved simply by optimizing body loading, while also extending battery life.

Removing the speed limiter does give electric golf carts a speed boost, but there are a number of safety, legal and warranty risks behind it. If you choose to do it, be sure to follow the 7 steps above carefully, prioritize safety, and refer to the model-specific details in your cart manual. Of course, there are safer options to increase speed, such as upgrading a high-performance motor, tires or battery. Whichever option you choose, always prioritize safety, comply with local laws and regulations, and enjoy the convenience and fun of a golf cart in a responsible manner.
