Head Stud & Bolt Kits

Head Stud & Bolt Kits for Performance Engines

Head stud and bolt kits clamp the cylinder head to the engine block with consistent, measurable force that factory head bolts can't match. Upgraded head studs are essential for any engine seeing increased cylinder pressure from boost, nitrous, or high compression — they provide more accurate and repeatable clamping load than torque-to-yield factory bolts that stretch permanently on first use.

OneFastShop carries head stud and bolt kits including ARP and equivalent high-performance head studs, head bolt kits, main stud kits, stud kits in 8740 chromoly, ARP2000, L19, and Custom Age 625+ materials, and application-specific kits for Honda B-Series, K-Series, Subaru EJ, Mitsubishi 4G63, Nissan SR20, RB26, VR38, Toyota 2JZ, GM LS, Ford Coyote, and many more engine platforms.

Every head stud kit at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're prepping a stock-block engine for boost, assembling a fresh rebuild, or upgrading to stronger fasteners on a race motor, OneFastShop has the head stud kit for your engine.
