GM Genuine Parts Clutch Pressure Plate and Disc Sets are designed, engineered, and tested to rigorous standards, and are backed by General Motors. This clutch disc is a flat plate with friction material on both sides, which works with the pressure plate. The plate is responsible for clamping the disc to the flywheel to get the vehicle moving. Furthermore, the pressure can be released from the clutch disc to disengage the engine from the drivetrain, allowing for shifting or stopping. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). WARNING: Cancer and Reproductive Harm
