Fabricated 8.4 Inch Housing Years after releasing our successful Rock Assault 9 Axle housing, we decided to add a Toyota 8.4 Inch 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 Inch differential non-Elocker.
These housings will stand up to the toughest terrain on earth. We started with a 0.25 Inch 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 0.5 Inch thick faceplate for anchoring the DOM axle tubes. Faceplate is machined after welding to ensure that the differential mounts flush. 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. The Rock Assault Fabricated 8.4 Inch Housings are offered with 3.5 Inch Outer Diameter axle tubes with your choice of 0.25 Inch or 0.375 Inch wall thickness. Includes two seal housing kits.
