Oil Pump 2-Stage R4 w/ Rear Drive

The Oil Pump 2-Stage R4 w/ Rear Drive from Peterson Fluid is a high-performance lubrication system component engineered for serious engine builders and performance enthusiasts who demand reliable oil delivery under extreme conditions. This pump is purpose-built for applications requiring dual-stage pressure regulation and rear-mounted drive configuration, making it ideal for custom engine swaps, circle track racing, and high-RPM competition builds where factory oil circulation proves inadequate. When you're running elevated boost levels, aggressive cam profiles, or extended track sessions, proper oil flow becomes critical to bearing longevity and overall engine survival.

The 2-stage design delivers progressive pressure response—ramping output as engine speed and demand increase while maintaining consistent film strength across the entire RPM band. Peterson's proven engineering minimizes pressure spike shock and prevents oil starvation during transient conditions, a common failure mode in heavily modified engines. The rear-drive configuration integrates seamlessly into custom oiling systems where conventional front-mount installations conflict with header geometry, turbo placement, or tight engine bay layouts. Precision-manufactured internals and robust construction ensure reliability through thousands of heat cycles and high-load operation.

This pump suits enthusiasts building LS, small-block Chevy, big-block, or import engine combinations where independent oil management takes priority over stock-location constraints. Whether you're designing a dedicated road-race platform, street-strip hybrid, or bracket-racing engine, the Oil Pump 2-Stage R4 w/ Rear Drive accommodates custom manifold configurations and alternative belt-drive arrangements. Verify drive coupling compatibility with your specific engine block and accessory mounting arrangement before purchase; this pump integrates with standard Peterson fluid system components and aftermarket oiling kits commonly found in performance engine packages.
