SBC.250in End Rail Space Kit

The Peterson Fluid SBC.250in End Rail Space Kit (MPN 09-1062) is a precision aluminum manifold end seal spacer designed for Small Block Chevy engine builds. This 0.250-inch thick spacer is engineered to maintain proper port alignment and seal integrity on manifold-equipped SBC applications. The kit includes roll pins for secure fastening and features raised port head design to ensure optimal fluid dynamics across the engine block's end rails.

Constructed from natural finish aluminum, this spacer kit delivers the exact dimensional control required in high-performance and competition SBC engine assembly. The 0.250-inch thickness is a critical specification—it establishes proper standoff distance between the manifold and block, preventing compression issues and flow restriction that compromise cooling efficiency and pressure distribution. The included roll pins provide fail-safe mechanical retention without welding or high-temp adhesives, a proven standard in race engine assembly. Compact dimensions (2.85 x 0.5 x 6.4 inches) and lightweight construction (0.15 lbs) ensure this spacer kit adds negligible weight while solving fundamental assembly requirements.

This kit is essential for engine builders, performance shops, and serious enthusiasts rebuilding small block Chevy engines where manifold-to-block interface precision cannot be compromised. Whether assembling a street performance build, off-road engine swap, or competition-grade SBC platform, proper spacer thickness prevents coolant bypass, maintains seal pressure, and extends overall engine reliability. The Peterson Fluid SBC.250in End Rail Space Kit represents the OEM-level component specification that professional engine shops rely on for repeatable, accurate builds.
