    DIFFERENTIAL

    Differential Gears

    From our many years of building the ford 9" centres we have decided on the Richmond or Strange US gear brand of diff gears with their proven strength and reliability in both street and strip application. A wide range of ratios are available from 3.00 to 1 through to 7.00 to 1 in 28 and 35 spline.
