- Supply gears are 9 percent wider than stock and standard S&S® oil pumps 28 percent wider than stock return gears ensure proper crankcase scavenging, reduce drag on the flywheels, and eliminate oil carryover
- Gears with fewer, but larger teeth provide increased oil volume for both supply and return sides of the pump
- Increased scavenging capacity results in less oil in the crankcase and less oil carryover
- Excess oil from pressure control valve is filtered & longer pump life
- Equipped with a stock length oil pump drive shaft
- Polished Billet Finish
Upgrade your Harley Davidson with the S&S Cycle Part Number 31-6302 high volume, high pressure oil pump kit designed for 1992 to 1999 Harley models including FLHS Electra Glide Sport, FXDB-D Dyna Glide Daytona, FXR Super Glide II, and FLSTN Heritage Softail Nostalgia. This universal cover maintains a slim profile, no thicker than a stock pump, ensuring a precise fit with minimal modification. The kit features supply gears that are 9 percent wider than stock and return gears that are 28 percent wider than standard S&S® oil pumps, providing enhanced crankcase scavenging while reducing drag on the flywheels. These larger gears with fewer teeth increase oil volume on both supply and return sides, promoting better lubrication and engine cooling.
The increased scavenging capacity results in less oil residing in the crankcase and minimizes oil carryover, contributing to cleaner operation and improved engine performance. Excess oil from the pressure control valve is filtered efficiently, extending the pump's lifespan and maintaining consistent pressure. The kit includes a stock-length oil pump drive shaft for seamless installation and features a polished billet finish, adding durability and a premium appearance to your engine. This high-performance oil pump kit is an ideal upgrade for riders seeking increased oil flow, better engine scavenging, and extended component longevity, ensuring your Harley runs smoothly and reliably under demanding conditions.
