Trail-Gear Fabricated Toyota 8.4" Axle Housing, 3.5" OD Tube

Years after releasing Trail-Gear's successful Rock Assault 9 Axle housing, they decided to add a Toyota 8.4” version to the Rock Assault lineup. This housing is built to the same specifications as the Rock Assault 9 axles, however, they are built to accept the popular Toyota 8.4” differential. These housings will stand up to the toughest terrain on earth.

Trail-Gear started with a 1/4" thick formed shell for the center section made out of 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 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. Trail-Gear also face the center section to ensure your differential mounts flush against the axle housing to prevent any leaks.

The Rock Assault Fabricated 8.4" Housings are offered with 3.5” OD axle tubes with your choice of 1/4” or 3/8” wall thickness.
