Bel-Ray Semi-Synthetic 3-Hole Complete Oil Change Kit Fits Harley-Davidson
Service day stops being a parts hunt. One pre-bundled kit drains the engine, transmission, and primary in the same session, leaving the bike with platform-matched oils in every sump and a fresh filter spun on. Sharp shifts, quiet clutches, and the kind of clean dipstick that tells a rider everything was done right.
Key Features
- Pre-bundled oil-change kit covering the engine sump and the separate (or shared) transmission and primary cases in one box, sized per platform variation
- Bel-Ray V-Twin Semi-Synthetic 20W-50 engine oil built on a synthetic ester base blended with select synthetic and petroleum stocks, rated API SN and JASO MA2 for V-twin wet-clutch compatibility
- Platform-matched transmission fluid: Bel-Ray V-Twin Sport Transmission Fluid for the Sportster shared trans/primary compartment, or Bel-Ray Big Twin Transmission Oil 85W-140 (API GL-5) for Evolution, Twin Cam, and Milwaukee-Eight separate gearboxes
- Bel-Ray V-Twin Primary Chaincase Lubricant included on Big Twin and Milwaukee-Eight variants for the separate primary chaincase
- HiFloFiltro HF171 racing-style oil filter included in Black (HF171BRC) or Chrome (HF171CRC) finish, both with a pre-welded 17 mm hex nut for easier removal
- Drain-plug O-rings supplied for every drain plug the variation services, two for the Sportster, three for Big Twin and M8
