Main Stud & Main Bolt Kits for Engines

Main stud and bolt kits secure the main bearing caps to the engine block with consistent, high clamping force that keeps the crankshaft properly supported under the extreme loads of high-horsepower and high-RPM operation. Upgraded main studs provide more accurate and repeatable clamping than factory main bolts, reducing main bearing cap movement and protecting the crankshaft.

OneFastShop carries main stud and bolt kits including ARP and equivalent main stud kits, main bolt kits, 2-bolt and 4-bolt main stud sets, 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 main stud kit at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're prepping a block for boost, assembling a fresh rebuild, or upgrading bottom-end fasteners on a race motor, OneFastShop has the main stud kit. Shop the full main stud and bolt kits collection today.
