Shim Kit - Rocker Arm Pedestal

The Shim Kit - Rocker Arm Pedestal for small block Ford engines is an essential precision component designed to maintain proper valve train clearance and geometry. This kit addresses a critical need in classic and performance Ford engine builds where rocker arm height must be fine-tuned to specification. Whether you're restoring an original small block or dialing in a performance build, proper rocker arm shimming ensures correct valve lash, prevents valve float, and protects against costly damage to the valve train.

This steel shim kit provides four precision thickness options—0.010, 0.020, 0.030, and 0.040 inches—allowing technicians to stack and combine shims to achieve exact pedestal-mount rocker arm heights. Steel construction ensures durability under the high-frequency cycling and thermal stress of engine operation. The shimming process compensates for manufacturing tolerances in cylinder head decks and rocker pedestals, eliminating guesswork and ensuring repeatable, accurate valve lash settings. Proper shimming directly impacts engine breathing efficiency, fuel economy, and longevity.

Builders and restoration specialists rely on this shim kit when working with small block Ford applications using pedestal-mount rocker arms. Installation requires careful measurement of existing rocker arm geometry and calculation of required shim stack height—a task best performed during initial engine assembly or complete top-end service. This kit is compatible with all small block Ford engines equipped with pedestal-mount rocker arm assemblies, making it indispensable for anyone seeking precision valve train control. The compact 3.35 x 1.65 x 3.5 inch package and light 0.2 lb weight make storage and transport convenient for shop or field use.
