When you upgrade the performance of your VW/Audi engine, many times you will exceed the capabilities of the factory hardware. ARP has the solution for you. Made out of premium grade 8740 chromoly, these studs have a strength rated far superior to OE and "aircraft" quality bolts. This material is heat treated to provide a tensile strength in the 200,000 psi range and is an excellent choice for building your high revving all motor, or forced Induction application.
