1/2 Stud - 2.750 Long Broached

The ARP 1/2 Stud - 2.750 Long Broached is a precision fastener designed for high-performance engine builds and critical structural applications. It is ideal for both automotive enthusiasts and professional mechanics who are working on stroker engines, turbo platforms, and heavily modified powerplants. This stud is engineered to provide reliability under extreme stress, making it a vital component in competition engines and supercharged builds.

Manufactured by ARP (Advanced Racing Products), this broached stud features a 1/2-inch diameter and a length of 2.750 inches, which is suitable for applications requiring extended engagement to distribute load effectively. The broaching process used in its production ensures a uniform thread geometry, eliminating inconsistencies and enhancing clamping force while reducing thread galling during installation. This construction allows for accurate torque readings, which are crucial for maintaining structural integrity under sustained load cycles.

Engine builders will benefit from the precise manufacturing tolerances of this stud, which ensure consistent preload values across the entire fastener set. This is especially important in forced-induction and high-RPM builds where torque specifications must be repeatable. The ARP 1/2 Stud is an essential component for anyone looking to reinforce factory components or assemble high-performance engines.
