Fabricated 8.4" Housing
Fabricated 8.4" Housing
Years after releasing our successful Rock Assault 9 Axle housing, we decided to add a Toyota 8.4” version to the Rock Assault lineup. This housing is built to the same specifications as our 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.
We 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. We also face the center section to ensure your differential mounts flush against the axle housing to prevent any leaks.
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).
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.
