The Speedmaster PCE287.1007 Main Stud Kit is engineered specifically for Ford 351W Windsor 2-bolt main engines, providing a more secure and reliable clamping solution than standard main cap bolts. The 12-point fastener design allows for easier socket access in tight engine bay environments, making installation and torquing straightforward during engine assembly or rebuild.
Upgrading to main studs helps distribute clamping load more evenly across the main caps, reducing cap walk and improving overall bottom-end integrity — a smart choice for street performance and rebuild applications. Designed to fit Ford 351 Windsor 2-bolt main blocks, this kit delivers a direct-fit solution backed by Speedmaster's commitment to performance engine components.
