Oil Pump 4 Stage R/S w/ Drive

The Oil Pump 4 Stage R/S w/ Drive by Peterson Fluid is a high-performance engine lubrication component designed for serious hot rodders, circle-track racers, and high-RPM street builds where reliable oil delivery under extreme conditions is crucial. This four-stage pump is engineered to maintain consistent pressure and flow at elevated engine speeds, making it a valuable addition for naturally aspirated performance engines and supercharged applications.

The four-stage design utilizes multiple gear chambers to supply oil at varying pressures simultaneously, which is beneficial in complex engine oiling systems where different components require different flow rates. The R/S designation indicates this pump features a right-side mounting configuration with an integrated drive shaft, allowing for direct installation onto compatible engine blocks without needing external drive coupling adapters.

This pump is particularly advantageous for competition engines and those upgraded for reliability and longevity. Its construction minimizes cavitation and maximizes volumetric efficiency across a wide RPM range, helping to prevent oil starvation during hard acceleration and sustained high-speed operation while maintaining proper pressure at idle.
