VW & Audi friction disc diamond coated Camshaft

Friction Disc (friction) between the camshaft and camshaft sprocket assembly for all VW and Audi engines.For motors with high torque.The problem of fitting is that at high torques between the camshaft and camshaft micro-movements arise. Even when using ARP bolts, the connection is not 100% free of play. Thus arise after a certain time a fatal defect on the camshaft. In the worst case, the complete camshaft breaks away!The friction disc increases friction by up to 300% and thus ensures a better connection to the camshaft camshaft sprocket.Since the disc is very thin (0.2 mm), there are no problems with the belt drive.Fits most VW and Audi engines. Inner diameter 22mm.A must for engines with a lot of power!
