Rock Assault™ 9 Axle Housing
After years of competition testing and engineering, we are confident that The Rock Assault 9™ 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 started with a 1/4" formed shell for thecenter section made out of A572 Grade 50 Steel for increased strength. This isa high-strength, low alloy, structural steel plate witha minimum yield strength of 50,000 psi! All of this is attached to an equallystrong 1/2" face plate for anchoring the DOM axle tubes. The axle tubesare secured by the industry's first 3-Point Attachment System™, giving thetubes superior support and engagement into the center section. We also face thecenter section to ensure your differential mounts flush against the axlehousing to prevent any leaks.
We also redesigned the Rock Assault™ 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..
