SBF 5/16 Rocker Arm Adjusting Kit

The SBF 5/16 Rocker Arm Adjusting Kit from Comp Cams is an essential tool for anyone serious about small-block Ford engine tuning and valve train optimization. Whether you're rebuilding a classic 289, 302, 351W, or 427, proper rocker arm adjustment directly impacts valve timing, fuel economy, and power output. This kit addresses the precision adjustment needs that arise during engine assembly, performance upgrades, or routine maintenance when valve lash requires fine-tuning to factory or custom specifications.

Comp Cams engineered this adjusting kit specifically for 5/16-inch rocker studs, the standard fastening specification on most SBF cylinder heads. The kit includes precision-machined adjustment components that allow you to dial in exact valve clearance without removing the rocker assembly, saving hours of labor during setup or teardown. Proper valve lash adjustment prevents excessive wear on pushrods, valve stems, and rocker arms—all common failure points when clearance is too tight or too loose. The components are manufactured to tight tolerances, ensuring repeatability across multiple adjustment cycles and long service life on the dyno or street.

Carburetor and fuel-injected small-block Ford owners, engine builders, and restoration specialists rely on this kit when final-tuning valve train geometry before first start-up or post-service verification. It's equally valuable for performance shops managing multiple engine builds, where quick, repeatable adjustments reduce bench time and minimize the risk of costly valve-to-piston contact in high-revving applications. Installation is straightforward for anyone with basic mechanical knowledge and a torque wrench, making this an affordable add-on to any SBF engine project. Compatibility extends across all small-block Ford generations using 5/16-inch stud rocker mounts.
