Axle Details

The Ford 9 Inch axle may have been discontinued by Ford in the 80's but thanks to its large 9" ring gear, drop out style 3rd member, 35 spline axle shafts, and easy maintenance, it has continued to grow in popularity and now has more aftermarket support than any other axle. Filthy Motorsports has got you covered with everything from OEM replacement parts to upgraded gears, axle shafts, and lockers, all the way up to custom fabricated housings and complete axles built for drag racing or professional desert racing.
