Oil Restrictors Dart / Chevy SHP 1 Pair .030

The Allstar Performance Oil Restrictors for Dart and Small Block Chevy engines are precision-engineered aluminum components designed to regulate oil flow to critical engine components. This pair of .030-inch restrictors uses an allen-head design for secure installation and represents a direct-fit solution for high-performance engine builders and rebuilders working with Dart SHP blocks and Chevrolet small block platforms.

Oil restrictors serve a specific function in engine lubrication systems: they meter oil pressure to rocker arms, cam followers, and other components that require controlled flow rather than full system pressure. The .030-inch orifice size on these units is critical for proper bearing protection and component longevity. Constructed from natural aluminum, they integrate seamlessly into both stock and modified engine configurations. The allen-head fastening system ensures a tight, reliable connection without stripping concerns common to other fastener designs.

Engine builders selecting oil restrictors must match orifice diameter precisely to their engine's specifications and intended operating parameters. This pair is engineered specifically for Dart SHP block architecture and small block Chevy configurations, making it the correct choice for those platforms. Allstar Performance's focus on precision engine components means these restrictors meet industry standards for dimensional accuracy and material consistency. Whether rebuilding a stock engine or assembling a high-rpm performance build, proper oil metering is non-negotiable for preventing bearing wear and maintaining engine reliability.

Serious engine builders and machine shops rely on matched components from established manufacturers like Allstar Performance to ensure complete system integration. These oil restrictors are a critical detail that separates professional-grade engine work from incomplete builds.
