The Rock Assault 9 is now available as a complete welded assembly from flange to flange including the Unit Bearing Pockets The new Rock Assault 9 is available in 3 great sizes to fit all applications. Designed for Wheel Mount Surfaces (WMS) of 60”, 65”, and 68”. We have made it easier for your axle upgrade or custom build. The assembly will also include the inner housing seals.
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 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.
Trail Gear 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.
