Bel-Ray Synthetic 3-Hole Complete Oil Change Kit Fits Harley-Davidson
Full-synthetic protection, ready in one box. The engine, transmission, and primary all get drained, filtered, and refilled in the same service, with platform-matched Bel-Ray fluids that hold their viscosity through long highway pulls and stop-and-go heat. The bike pulls cleaner, shifts crisper, and goes longer between intervals.
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 Synthetic Engine Oil 20W-50, a full-synthetic blend built on a polyalphaolefin (PAO) and synthetic ester base, 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

- 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

I haven’t actually used it yet . I’ve been running Redline oil for several years and heard that Bel-Ray is comparable and has certain qualities that I wanted to see if were true. Good experiences so far though.
