You lose all energy on a regular gas cart when stopping and commencing, so climbing hills can be challenging. This front clutch set allows your golf cart to idle, so you maintain more power and avoid those jerky take-offs. The Clutch Tuning Kit fits 1992 & up Club Car DS and 2004-2015 Precedent non-EFI gas models. So as long as you have a carb, you are good to go.These aftermarket kits include one Club Car DS clutch tuning spring and one ignition conversion harness specially designed to work in conjunction with the clutch upgrade to give you more power. We need to bypass a switch that allows the engine to idle, and this harness does that as well. Keeping your engine running get maximum acceleration is what this kit is all about. This spring is for the drive or primary OEM clutch that is on the engine. Another cool feature is the conversion to a golf cart key switch ignition. You still have to start it with the pedal the first time, but you are off to the races. Call Buggies Unlimited and get one coming.
