Setting up a rear axle for the best performance is fleeting. Track or street conditions, weather, and noise are all elements that require changes. Winters 10-spline quick-change helical gears are an excellent choice for normal driving at highway speeds due to their reduction in gear noise. Although stronger than straight cut gears, these helical units are not recommended for racing due to the excessive axial loads. Simply install Winters 10-spline quick-change helical gears, keep endplay limited to .010 max, add sufficient oil to the differential, and enjoy a quiet ride till your next trip to the track.
