Ford Racing Rocker Arm Shim Kit

The Ford Racing Rocker Arm Shim Kit (also called a rocker arm pedestal shim kit or rocker arm spacer kit) helps set correct lifter preload in Ford performance valvetrains. It is meant for use with bolt-on roller rocker arms. Precision shims let you fine-tune valvetrain geometry after machining or a camshaft upgrade.

Key Features:

• Reduces lifter preload so valve operation stays correct with bolt-on roller rocker arms
• Shims come in more than one thickness. You can use a single shim or stack them for finer adjustment
• Helps optimize valvetrain geometry in small block Ford performance builds
• Made by Ford Racing, Ford's factory performance parts brand
• Simple to install during rocker arm setup

Check preload during assembly. If you need more adjustment than the shims provide, a different length pushrod is the usual fix. This kit is a simple, affordable way to get precise valvetrain setup with Ford Racing quality.
