    Helical Cut design allows for quiet gear operation compared to straight cut!

    Top Speed increase : 5-7 MPH with 15 x 50, and 6-12 MPH with 14x42

This is an easy install, however, we would recommend  replacing the bearing at this time and make installation a breeze along with maximizing performance! You will probably need a new gasket too.
