The Earls Performance Cylinder Head Fasteners offer the ideal solution for replacing OE torque-to-yield style bolts when removing cylinder heads. These reusable fasteners emphasize outstanding durability and long service life through a high-grade Chromemoly alloy steel structure with a 170,000 psi yield strength. These fasteners are built to be approximately 15% more resilient than conventional grade 8 bolts.

The Earls Performance Cylinder Head Fasteners feature a reduced wrench size for added socket clearance, while a widened flanged head offers the necessary support to accommodate thicker washers. Thanks to a sleek black oxide-coated finish, these fasteners ensure superior corrosion resistance and long-lasting good looks. These high-quality fasteners are available as complete engine sets to ensure a comprehensive and hassle-free means of elevating the performance of your engine.
