S&S Cycle HVHP Polished Billet Oil Pump Kit with Gears for Custom Big Twin Builds

Adequate oil delivery is the difference between an engine that thrives and one that fails, and that gap becomes critical as performance demands increase. This HVHP pump upgrades both supply and return capacity, ensuring the engine receives consistent flow at every rpm while scavenged oil returns efficiently to keep the crankcase clear.

Key Features

• High Volume/High Pressure (HVHP) design with a new gear tooth profile using fewer but larger teeth for increased oil volume
• Supply-side gears are 9% wider than stock for increased delivery volume
• Return gears are 28% wider than stock to ensure efficient oil scavenging and crankcase breather management
• Universal cover with multiple oil feed and return port options for maximum installation flexibility
• Complete kit includes supply gears, return gears, drive shaft, drive shaft keys and snap rings, check ball and spring, pressure valve spring, cover screws with O-rings, hose fittings, plugs, screws, gaskets, mounting hardware, oil pump drive shaft gear, oil pump pinion shaft gear, S&S breather gear and shim kit, and instructions
