ARP main stud kit for the Audi inline-five, replacing the factory main cap bolts with heat-treated studs for consistent clamping load and improved bottom-end strength under boost or high RPM. Studs thread into the block and torque against ARP nuts, giving a more accurate and repeatable clamp than stretch bolts. Kit includes the main studs, nuts, washers, and ARP Ultra-Torque assembly lube.
