Oil Pump 2 Stage L/S w/ Rear Drive

The Peterson Fluid Oil Pump 2 Stage L/S with Rear Drive (part number 04-2006) is a high-volume dry sump oil pump engineered for racing engines and high-performance applications requiring precise oil delivery and scavenging. This external two-stage pump combines both pressure and scavenge functions in a single compact unit, eliminating the need for separate pump assemblies and reducing overall system complexity.

The two-stage design delivers consistent oil flow across varying engine speeds while the rear drive configuration integrates seamlessly into existing engine block setups without requiring accessory mounting brackets. Left-side mounting orientation suits applications where belt drive systems or auxiliary gear arrangements benefit from this orientation. The high-volume capacity ensures adequate oil supply to bearings, valve trains, and other critical engine components during sustained high-RPM operation, while the scavenging stage actively removes oil from the crankcase to maintain optimal crankcase vacuum and reduce parasitic drag on internal components.

This pump serves dedicated racing programs, off-road competition platforms, and custom engine builders who prioritize reliability under extreme conditions. Dry sump configurations are standard in circle-track racing, road course competition, and vehicles experiencing sustained high-G maneuvers where conventional wet sump lubrication becomes unreliable. The external pump design allows for modular oil system architecture—users can locate tanks, coolers, and filters independently of engine position, optimizing weight distribution and thermal management.

Peterson Fluid specializes in dry sump and high-performance lubrication systems trusted across motorsports applications. This two-stage design is universal in mounting compatibility, allowing integration into diverse engine platforms with proper adapter selection. Weighing 6 lbs with compact dimensions of 9 x 11 x 12 inches, the pump balances robust internal components with space efficiency for tight engine bays.
