Next to the engine, this part is probably the most important in making any gas golf cart actually move. The Club Car DS - Precedent Gas Drive Clutch is the pulley that the belt goes around on the motor. It is a centrifugal unit that uses the engine's rotation to propel the cart by spinning a drive belt attached to the rear end. There are all kinds of moving parts internally, like weights and pins that can get thrown out of place, making it sound like a can of rattling BBs are lose under the seat.What comes in the box? You get a clutch assembly, meaning we put it together for you to save you time and money. It's rated at 5000 RPM, and it includes a fixed sheave and starter generator pulley. This is a worthy note as you need a new belt when you use this clutch. Make sure you call Buggies Unlimited and get everything you need the first time when it comes to your golf cart parts.
