Rock Assaultª 9 Axle Housing

After years of competition testing and engineering, we are confident that The Rock Assault 9ª Axle Housing is the strongest 9" axle housing on the market. This housing has been tested in W.E. Rock, CalRocs, and King of the Hammers, so we know it will stand up to the toughest terrain on earth. We are so sure that this is the best axle housing in the industry, we are backing it up with our world famous no questions asked warranty.

We started with a 1/4" formed shell for the center section made out of A572 Grade 50 Steel for increased strength. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 50,000 psi! All of this is attached to an equally strong 1/2" face plate for anchoring the DOM axle tubes. The axle tubes are secured by the industry's first 3-Point Attachment Systemª, 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 also redesigned the Rock Assaultª 9 Axle Housing to allow for the use of both a 9" and 10" differential! This will give you the option to create an even stronger axle and give you that piece of mind knowing you have the strongest axle under your rig..
