Upgrade your engine's lubrication system with the S&S CYCLE HVHP Oil Pump Kit, part number 31-6302, designed for maximum oil flow and efficiency. This high-volume pump features a new gear tooth profile with fewer but larger teeth, providing an increased oil volume for both supply and return sides. The supply-side gears are 9% wider than stock, while the return gears are 28% wider, ensuring that the additional oil supplied to the engine is effectively scavenged and returned to the oil tank. This design helps reduce oil in the crankcase breather, promoting cleaner operation and improved engine longevity. The kit is available in both universal and standard styles; the universal version offers multiple oil feed and return options for flexible installation, whereas the standard style is compatible with '92-'99 style oil line hookups, making it suitable for a range of applications. Included in the kit are essential components such as supply and return gears, drive shaft, drive shaft keys, snap rings, check ball and spring, pressure valve spring, cover screws with O-rings, hose fittings, plugs, gaskets, mounting hardware, and the necessary gears for the oil pump drive and pinion shaft, along with a breather gear and shim kit. These components work together to ensure a reliable and high-capacity oil supply tailored to high-performance engines. Constructed in the USA, this oil pump kit is an ideal upgrade for enthusiasts seeking enhanced lubrication and engine durability, whether for custom builds or performance upgrades. Proper installation guarantees optimized oil flow, reducing wear and maintaining consistent engine performance under demanding conditions.
