Rock Assault Nine Rear Axle Housing with bearing pockets 3.5 Inch x 3/8 Inch x 60.0 Inch WMS with Shafts Detroit.
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 of 60, 65, and 68. We have made it easier for your axle upgrade or custom build.
We started with a 1/4 Inch 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. All of this is attached to an equally strong 1/2 Inch 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.
We have redesigned the Rock Assault 9 Axle Housing to allow for the use of both a 9 Inch and 10 Inch 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.
We are so confident our Rock Assault 9 is the strongest on the market that we are backing the product with our legendary No Questions Asked Warranty.
Note: Wheel Mount Surface Dimensions reached using TG Unit Hub, TG Number 144012-K, and 1/4 Inch Brake Hats. Using other components will vary final results. Pinion is offset 2.125 to allow for same size axle shafts for passenger, and driver side. The differential bolt pattern on 9 Inch Axle Housings are NOT universal.
