Looking for a budget-friendly, rock-solid foundation for your custom rear suspension? Look no further. Our fabricated steel Ford 9 inch axle housing kit including two axles for maximum durability.

Fabricated with the Builder in Mind

This housing is pumpkin-centered with uniform-length axle tubes, side-to-side. So mounting suspension brackets, especially on triangulated 3-link and 4-link systems, is much easier. Note that the pumpkin-centered design will offset the pinion yoke about 1\" to the passenger side.

Axle tubes are 3” O.D. with a 3/16” wall thickness. Heavy-wall tubes, along with a larger center section, significantly reduce distortion during welding of rear-link brackets or spring pads. Billet steel “New Big Ford” (Torino) style bearing ends are fixture-welded (3.150” O.D. bearing, with 2.50” axle flange offset).

Total wheel-to-wheel mounting surface width is 56\" (from hub-to-hub). The pumpkin is centered in the housing, which puts the pinion 1\" offset from center, requiring different length axle shafts. This 56\" rear end housing kit includes two 31 Spline 29.5\" cut-to-fit axles The housing includes (8) T-bolts for the axle bearing retainer plates and (10) studs for the third member.
