Allstar Performance Oil Restrictors are designed for Dart SB Chevy SHP engine blocks. These restrictors are compatible with the priority main oil system and regulate oil flow to the upper part of the engine. This helps prevent oil starvation in the crankcase during continuous high-RPM operation. The kit includes five restrictors, an additional O-ring, and instructions for installation.
