    Will It Fit Your Vehicle?


    The Gear-X countershaft 1st gear requires that you use the Gear-X mainshaft and Gear-X 2nd gear in order to install this 1st gear.

    This gear will not work with an OEM mainshaft.

    The ratio is 2.3125 and is rated for up to 500 horsepower.

    This is the first gear from the Gear-X Drag Kit, Pro Spec I, Pro Spec II and Pro Spec III gear sets.
