Features
This kit is an aftermarket solution. It is not intended to be a direct installation or OEM replacement. Due to changes in production in certain years, your application may require modifications beyond the instructions for this kit to install properly. If your axle shaft flange or axle shaft register exceeds the diameter that clears the rotor dimensions, you will need to machine the axle flange and/or the rotor to clear the diameter required.
