This purpose-built kit addresses every critical lubrication point your V-Twin drivetrain demands – delivering smooth shifting, quieter operation, and the lasting engine protection that experienced riders rely on between long hauls.
Key Features
- Covers all three drain points for a complete 3-hole service: engine, transmission, and primary chaincase – everything needed in a single purchase
- HiFlofiltro HF171 series oil filter included in black or chrome with a pre-welded hex nut for tool-assisted removal
- O-rings included where required – no additional hardware needed to complete the service
- Exclusive Bel-Ray anti-wear chemistry reduces bearing and valve train wear and prevents piston and ring scuffing
- Low-volatility formulation resists viscosity breakdown and prevents sludge and deposit buildup for extended drain intervals
- Advanced multi-grade formula enables safe cold starts and maintains protection across a wide operating temperature range
- Sportster kit includes Bel-Ray V-Twin Sport Transmission Fluid – services both the transmission and primary chaincase in a single compartment
Technical Specifications

Fitment Notes
- A dry fill of the primary chaincase on Twin Cam and M8 drivetrains requires one additional quart of primary chaincase lubricant beyond what is included in the kit
- The Sportster XL transmission and primary chaincase share a single oil compartment – no separate primary oil is required
- Riders with a 2017 model year should confirm their engine generation (Twin Cam or Milwaukee-Eight) before selecting a kit, as both were produced that year
- Please review the Fitment tab for the complete year and model compatibility breakdown
