SBC .500in End Rail Spac Kit

The Peterson Fluid SBC .500in End Rail Spacer Kit (Part No. 09-1064) is a versatile solution for small-block Chevrolet engine builders. This spacer kit is useful for both high-performance engine assembly and standard rebuilds, providing essential support during installation and operation. It addresses the need for proper clearance and alignment between the end rails and cylinder block.

With a .500-inch spacing specification, this kit compensates for manufacturing variations in block casting and rail dimensions, helping to prevent binding or excessive play. Manufactured by Peterson Fluid, a trusted name in precision engine components, this kit is designed to exacting tolerances to aid in assembly. Its compact and lightweight design—just 0.27 lbs—facilitates easy handling and installation.

This spacer kit is ideal for machine shops, engine builders, and DIY mechanics performing SBC rebuilds, especially when working with stock blocks or aftermarket decks. It is particularly beneficial in combination builds where tolerance stack-up is a concern, ensuring a reliable fit without interfering with adjacent components or gasket surfaces.
