Fabricated Front Axle Builder Kit
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”, 8″ E-locker, or 8.4″ 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 Knuckle balls. You can cut the axle length to size and weld your knuckle balls where you need them. The included knuckle balls are brand new so that you no longer need to source 30 year old knuckle balls. Our knuckle balls are forged from 1035 steel, making them much stronger than stock, eliminating closed or bent knuckle balls.
We started with a 1/4″ 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 1/2″ thick faceplate for anchoring the 3.5” 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 1/4-inch wall tube version saves weight while the 3/8-inch wall tube version provides even greater durability. We also include seal housing kits for both sides. Set screw holes for seal housings can be plug welded if using Toyota inner axle seals in the knuckle balls.
We recommend the addition of our Axle Housing Inspection Hole Kit to allow for easy fluid level and ring gear visibility. Just select “With Inspection Hole Kit Installed” in the drop down menu above. The kit is also available in a DIY installation version (requiring drilling through the differential housing and welding on a threaded bung).
