In high rpm, high power engines, fastening the flywheel to the crankshaft becomes increasingly difficult due to the instability of a flexing crankshaft. In extremely high horsepower applications it is not unheard of for the flywheels to actually come off! These special, heavy duty ARP bolts are uprated from factory units, and are much higher quality and strength. They are made from arp 8740 alloy and feature a 190,000 psi tensile strength. This is for ONE bolt, order 6 bolts for most vw 4 cylinders up to 2008 and 10 bolts for VR6 and most other V6 and V8 VW / Audi applications. 4 cylinder TSI requires 8 bolts.
