SBC Stand Shim Kit .030/.060

The T and D Machine SBC Stand Shim Kit .030/.060 is a precision rocker arm shim assortment designed for small block Chevy and Ford rocker arm applications. This steel shim kit contains eight 0.030-inch thick shims and eight 0.060-inch thick shims, providing fine-tuning capability for proper valve train geometry and preload setup. Accurate shimming is critical for engine reliability and correct valve lash adjustment in performance and street engine builds.

Rocker arm stand shims are essential for adjusting the height and geometry of the rocker assembly relative to the pushrod and valve stem contact point. The dual-thickness format—combining 0.030-inch and 0.060-inch options—allows builders to stack shims in increments as small as 0.030 inches to achieve precise clearance and alignment. Steel construction ensures dimensional stability under sustained engine temperatures and load cycles. Proper shimming prevents excessive valve stem wear, reduces unwanted rocker geometry angles, and ensures consistent valve opening and closing characteristics across the rpm range.

This kit is intended for small block Chevy and small block Ford engine builders, machine shops, and serious enthusiasts performing rocker arm assembly, valve train service, or engine blueprint work. Whether building a race engine, street performance engine, or restoring a classic small block, correct rocker arm stand shimming is non-negotiable for reliability and proper valve train function. T&D Machine shim kits are widely used in engine building shops and are recognized for consistent manufacturing tolerances.

Rocker arm shimming is a foundational step in any serious small block Chevy or Ford build. Unlike generic shim assortments, this purpose-designed kit provides the specific thicknesses most commonly needed for SBC and SBF rocker arm geometry correction, eliminating the need to source shims from multiple vendors or compromise on precision.
