Fabricated Axle Housing Builder Kits Known for their strength, light weight, and simplicity, Toyota axles are the perfect fit for many custom off-road projects. Factory Toyota axle housings are available in a narrow range of widths which may not fit your crawler well. Trail-Gear Fabricated Axle Housings allow you to use Toyota axles in nearly any width from the narrowest of moon buggies to full-size trucks.

Trail-Gear’s Fabricated Axle Housings Builder Kits are available for Toyota 8.0 Inch, 8.0 Inch E-locker, or 8.4 Inch differentials and feature all of the same specifications as our Rock Assault 9 axles. Fabricated Axle Housing Builder Kits include a 75-Inch wide Trail-Gear axle housing and two housing ends. You can cut the axle length to size and weld your axle tube flanges where you need them.

We started with a 0.25 Inch thick formed shell for the center section made out of ASTM A36 steel. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 36,000 psi! All of this is attached to an equally strong 0.5 Inch thick faceplate for anchoring the 3.5 Inch OD DOM axle tubes.

The axle tubes are secured by the industry’s first 3-point attachment system, giving the tubes superior support and engagement into the center section. We also face the center section to ensure your differential mounts flush against the axle housing to prevent leaks.

We offer two different axle tube wall thickness options. The 0.25 Inch wall tube version saves weight while the 0.375 Inch wall tube version provides even greater durability. We also include seal housing kits for both sides. Flanges are CNC machined from Billet steel and work with all factory axle and brake components.
