This performance clutch kit is a 30% improvement over the stock factory clutch. The Centerforce clutch is a heavy duty unit with extra clamping power to handle improved performance engines and larger tires yet its static pedal pressure remains as light as stock. The Centerforce clutch is a must for all Nissans built for off-road use. The kit comes complete with clutch disc and pressure plate. The throwout bearing is available from factory Nissan.
