The Peterson Fluid Systems R4 three-stage oil pump uses a twisted-lobe rotor geometry and all-aluminum rotors to lower weight and increase capacity in a compact unit. The internal scavenge manifold and low-profile screw-in fittings keep installation space minimal. This right-side, rear-drive unit provides 1.4" pressure and 1.2" scavenge, offering a higher-capacity option for race-oriented oiling systems.
