S&S CYCLE HVHP Oil Pump Kit - Universal 31-6302

Stock oil pumps struggle to handle the demands of modified engines—they under-deliver volume on the supply side while failing to scavenge adequately on the return, leading to excessive crankcase pressure and oil aeration. The S&S CYCLE HVHP Oil Pump Kit solves this with significantly wider supply and return gears that maintain proper oil circulation under high RPM and boost conditions, protecting your engine's internals and extending component life. This is a critical upgrade for any serious build where reliability matters as much as power.
