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 the center section. Then we attached a 1/2″ face plate. Finally, we connected the DOM axle tubes to the center section with 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. Axle housing is shipped with inner axle seal and seal housing.
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 peace of mind knowing you have the strongest axle under your rig.
NOTE: This product includes (2) Axle Seal Housing Kits.
