Reduce Shock Loading.  Our Weddle Racing input shafts are much more effective at dampening shock loads than the stock VW input shafts, and they work to significantly reduce stresses in the transmission and drivetrain. The diameters and fillets have been carefully designed to maximize torsional twist without sacrificing strength. This can make a huge difference in the longevity of components, especially in high performance applications. Each shaft is manufactured from custom-spec ultra high quality 300M steel, through-hardened, and shot peened to maximize strength and fatigue resistance.
