This ARP High Strength Flywheel Belt for VW & Audi models (check make & models above) is for one bolt. Order 6 bolts for all VW/Audi 4 cylinders up to 2008 and 10 bolts for VR6 and most other V6 and V8 VW / Audi applications. If you have any questions, feel free to contact us.
Fastening the flywheel to the crankshaft on high RPM/horsepower engines becomes increasingly difficult due to the instability of a flexing crankshaft. This flexing can cause the flywheel to actually come off. These special, heavy duty ARP bolts are uprated from factory units, and are much higher quality and strength.
