This is the one that doesn't slip. It just grabs, locks up and goes like hell. Don't try to run it on the street because it's got the radical race car "in or out no messing around action." 4 Ceramic Discs are riveted and heat bonded to a heat-treated steel center to provide race performance for all VW engines. You can match it to a 2000 lb. Race Clutch for bigger engines or run it with a stock clutch for smaller engines. It's perfect for sand drags, quarter mile competition and super hot dogging.
