Rugged and reliable, the Ford 9-inch is the axle of choice for many racers, off-roaders, and performance enthusiasts. Named for its 9-inch diameter ring gear, the Ford 9-inch rear end accepts a wide variety of gearset ratios and features a drop-out third member for easy ring and pinion swaps right on your workbench. You can even carry multiple center sections for quick bolt-in ratio changes to get the most out of any track or trail conditions. Plus, the units came factory-equipped with 28- or 31-spline axles and differentials.

Rugged and reliable, the Ford 9-inch is the axle of choice for many racers, off-roaders, and performance enthusiasts. Named for its 9-inch diameter ring gear, the Ford 9-inch rear end accepts a wide variety of gearset ratios and features a drop-out third member for easy ring and pinion swaps right on your workbench. You can even carry multiple center sections for quick bolt-in ratio changes to get the most out of any track or trail conditions. Plus, the units came factory-equipped with 28- or 31-spline axles and differentials.
The Ford 9-inch rear end was introduced in 1957 and discontinued in 1986. The good news is you don’t have to scour the junkyard or prowl a swap meet to equip your ride with the famous 9-inch rear end. You can choose from an extensive selection of aftermarket Ford 9-inch assemblies that feature performance enhancing improvements such as stronger alloys, reinforced pinion bearing supports, and disc brakes. If you have an original Ford 9-inch housing you have lots of options for upgrades, too. From ring and pinion sets, to fully assembled third members, differentials, spools, bearings, axles, and more, Summit Racing has everything you need to build an unstoppable Ford 9-inch rear end.
