This exhaust manifold bolt is designed for GM Gen III and Gen IV LS engines and serves as a direct-replacement or spare bolt for header/exhaust manifold installation or repair. Sold individually, it allows builders to replace only the quantity needed rather than an entire bolt kit. The bolt is appropriate for exhaust manifold/header flange mounting in stock or aftermarket applications.
