Brand: Red Line Synthetic Oil
Red Line ShockProof Gear Oil has been well proven in many years of use in a variety of racing transmissions. Now that same protection is available for your American V-Twin transmission! The unique solid dispersion formula helps to cushion gear teeth to minimize wear. It even reduces the loud shifting "clunk" these transmissions are known for. Suitable for all OEM American V-Twin transmissions as well as aftermarket versions from Baker, JIMS, S&S, and others. Offers the protection of a 75W250 gear oil, but with the lower internal fluid friction of much lighter 75W90 oil. This results in better efficiency and more power at the rear wheel.
