This LUK Clutch Kit is compatible with Porsche 911s of model years 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985 and 1986. A functioning Clutch Kit helps the driver switch gears by utilizing the motor's flywheel and a clutch plate; as the clutch is engaged, the components separate, disconnecting the engine from the drive train and allowing the engine to spin without moving the vehicle. Generally a vehicle clutch is a durable system, with use the clutch plate can become worn and need replacement. Porsche 911s of model years '75, '76, '77, '78, '79, '80, '81, '82, '83, '84, '85 and '86 will work with this part. Different cars and trucks are unlikely to be compatible, so this element is not designed to be used on those vehicles.
