Golf Car Catalog offers rpm limiters for many Club Car golf cart, utility vehicle and personnel carrier models. As the name implies, this component limits the RPMs (revolutions per minute) of the golf cart's engine. it does this in an effort to prevent damage due to excessive rpms. Many golf cart manufacturers use a ground speed governor as part of the differential which mechanical controls the top speed. However, Club Car has gone a step further by installing these electronic rpm limiters so they can also control the speed electrically as well.
