These are main studs, not head studs. Main and head studs serve different purposes—selecting the right one is crucial. 

Why Main Studs? 

Main studs provide superior clamping force compared to main bolts, reducing wear on block threads and assisting with main cap alignment. Unlike bolts, which twist during tightening, studs remain stationary, reducing the chance of main cap walking under high loads. They are especially beneficial in high-performance applications where increased stability and durability are required.

Disclaimer: Designed to secure crankshaft main bearing caps. This is NOT a head stud kit.
