Audi V8 main studs are of the single use stretch type and will not hold torque if re-used.
These studs solve that problem.
They will fit all 32V and 40V engines.
ARP uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality.
Then, each stud is placed vertically in special racks and precisely heat-treated to 190,000 psi tensile strength.

These studs are manufactured and boxed specifically by ARP for Advanced Automotion.
