Info

Looking for a budget-friendly, rock-solid foundation for your custom rear suspension? Look no further. Our fabricated steel Ford 9 inch axle housings feature all-new, USA-made components for maximum durability. It’s an evolution of the rugged and reliable 9 inch Ford platform.

Designed 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. Unlike factory stamped housings, these fabricated plate-steel center sections provide a wide, flat surface for easy bracket attachment. 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).

Improved Design for Greater Durability 

In addition to the heavy-duty bearing ends, the axle tubes are supported with bracing inside the large center housing. This reduces flex in the rear end housing, which is something you won’t find on stamped factory 9 inch housings. Plus, gears stay well-lubed and run cooler thanks to a large-capacity fabricated center (holds more gear oil than stamped housings). Axle is vented on the driver’s side.

Yet, with improved durability, our fabricated axle housing is on average 2 pounds lighter than stock style housings of the same size! Add your choice of axle shafts and third member (sold separately), and you are ready to roll. Equip your race car, hot rod or 4X4 with Ford 9 inch parts from Speedway Motors to ensure there are no weak links in your driveline combination. 

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" housing includes one 28-5/8" long axle and one 26-3/8" long axle. This housing includes (8) T-bolts for the axle bearing retainer plates and (10) studs for the third member.

Forged Steel Axles

Our improved axle housings deserve equally strong axles to drive your street machine. Two custom cut Currie axles made of heat-treated 1541 forged alloy steel have the strength to handle the horsepower. Axles are 31-spline, with pressed on bearings and include axle shafts, axle bearings, axle seals, and bearing retainers. Flanges are dual-drilled for both 5 on 4-1/2" Ford/Mopar and 5 on 4-3/4" GM wheel bolt patterns, and include two sizes of wheel studs (1/2"-20 Ford/Mopar and 7/16"-20 GM). 

  • Made in the USA fabricated steel center section
  • 3" O.D. axle tubes with 3/16" wall thickness
  • Axle tubes are internally reinforced for additional strength, less flex
  • Billet steel "New Big Ford" (Torino) style bearing ends

  • Housing measures 51" from flange-to-flange
  • Assembled rearend measures 56" from hub-to-hub (axle flange face-to-face)
  • Includes one 28-5/8" long axle and one 26-3/8" long axle
  • Improved housing design weighs approximately 2 lbs less than stock-style fabricated housings
  • Centered pumpkin w/ 1" offset pinion yoke for easy suspension mock-up
  • Greater-than-stock capacity center section holds more gear oil and runs cooler
  • Requires different length axle shafts, left/right
  • Includes vent on driver side axle tube
  • Includes studs for 3rd member and 3/8” T-bolts for bearing retainer plates

Notes

When utilizing an aftermarket axle with disc brake conversion kits, it may be necessary to reduce the diameter of the axle flange to a diameter necessary to adequately fit inside the required Clearance I.D. that the brake hat/brake rotor will require.  (see above diagram for illustration)
