RTS offers Ford 9" Fabricated Rear Axle Housings in a variety of configurations, RTS rear axle housings are designed and manufactured to be more rigid and stronger than OEM housings. Depending on the application, they are either fabricated from Mild Sheetmetal or regular Mild steel depending on the look you require, fixture-welded to ensure proper alignment, slotted for full tube engagement, and reinforced at critical areas to reduce center section and axle tube flex. Whether your car is headed for the street, the track, or the drag strip, customize your car's rear-end with a RTS rear axle housing so it will meet or exceed your expectations
