S&S CYCLE HVHP Oil Pump Kit - Universal 31-6302 for High-Performance Engines

The S&S CYCLE HVHP Oil Pump Kit, Part Number 31-6302, is engineered to enhance oil flow and improve lubrication efficiency in high-performance motorcycle engines. Featuring a new gear tooth profile with fewer but larger teeth, this pump design provides increased oil volume for both supply and return sides, ensuring optimal engine protection and longevity. The supply-side gears are 9% wider than stock, delivering more oil to critical engine components, while the return gears are 28% wider, effectively scavenging and returning excess oil to the oil tank. This balance reduces oil in the crankcase breather, promoting cleaner engine operation and reducing maintenance needs. The kit is available in universal and standard styles, with the universal version offering multiple oil feed and return options for maximum installation flexibility, accommodating custom setups. The standard style is tailored for '92-'99 style oil line hookups, simplifying direct replacements for compatible engines. Each kit includes essential components such as supply gears, return gears, drive shaft, drive shaft keys, snap rings, check ball, check ball spring, pressure valve spring, cover screws with O-rings, hoses, plugs, screws, gaskets, mounting hardware, and detailed instructions, ensuring comprehensive installation support. Made in the USA, this oil pump kit is crafted from high-quality materials to withstand demanding riding conditions, delivering reliable lubrication and engine performance. Whether upgrading an existing system or building a custom high-performance engine, the S&S CYCLE HVHP Oil Pump Kit offers an effective solution for optimal oil flow and engine protection.
