ARP Perma-Loca c stud girdle 7/16-20 x 2.600 .750 body diameter

This ARP Perma-Loca stud girdle is designed to reinforce your connecting rod bolts, adding significant strength to your engine's rotating assembly. It works by tying the connecting rod bolts together, preventing them from flexing or stretching under high stress. This is a popular upgrade for performance builds where increased cylinder pressures and RPMs are expected, helping to keep your bottom end together when it matters most.

ARP uses high-strength 7/16-20 x 2.600 inch studs with a .750 inch body diameter for this girdle. The Perma-Loca design ensures a secure and consistent clamping force, which is crucial for maintaining proper rod bolt tension. This well-built component is a smart addition if you're pushing your engine beyond stock capabilities, offering peace of mind and improved reliability under demanding conditions.
