Pump 1 Stage L/S Std. Vol. 1.2in Body

Part #: 04-1004

Peterson Fluid Systems is proud to make one of the best performing and most versatile oil pumps available in motorsports. The R4 Oil Pump is the result of more than 50 years of fluid engineering and racing experience. Peterson pioneered the twisted lobe rotor design to deliver solid oil pressure, even in high temperature low viscosity oil set-ups. Its scavenge sections pull serious vacuum too. Peterson provides heavy-weight performance without the heft: shallow depth screw-in fittings, profile machining, and aluminum rotors makes the R4 one of the lightest pumps available. The pump's steel drive shafts are 5/8 in. diameter with a 3/16 in. keyway to receive an appropriately sized pulley or machined with a 3/8 in. male hex for cam or accessory drives. R4 pumps have a rear drive provision which allows for the direct mounting of many popular drive accessories like fuel pumps, vacuum pumps, or power steering pumps with the appropriate adapter. The most decerning engine builders trust the R4 Oil Pump to protect and extend the working life of their engines by having the proper pressure with the proper volume at the right time. Maximizing horsepower with the pump's ability to create crankcase vacuum as it scavenges and reduces windage in the oil pan. Equally at home on a 5 second drag car, endurance racing at Le Mans, punishing deserts of Baja or even at the local dirt track, Peterson has an R4 oil pump to ensure a first-place finish in any race. Proudly made in the USA, all pumps are machined, assembled, and tested in house, in Longmont, Colorado. Custom configurations are available, contact the Peterson Fluid Systems sales and customer service team for additional options.
