Rock Assault™ 9 Rear Axle Housing w/Shafts
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 steel shell for the center section for increased strength. All of this is attached to a 1/2″ faceplate 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 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.
Also available in 3.5″ O.D. axle tubing
*Custom sizes available. Please call to place your order for a custom-size axle housing.*
**MADE IN THE USA**
NOTE: WMS (Wheel Mount Surface Dimensions) reached using TG Unit Hub, TG# 144012-KIT, and 1/4″Brake Hats. Using other components will vary final results. The pinion is offset 2.125 to allow for same size axle shafts for passenger, and driver side.
Note: The differential bolt pattern on 9″ Axle Housings are NOT universal. Please check before cutting or welding.
