Rock Assault 9" Rear Axle Housing With Shafts
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 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.
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
**MADE IN THE USA**
NOTE: WMS (Wheel Mount Surface Dimensions) reached using TG Unit Hub, TG# 144012-K, and 1/4"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.
Note: The differential bolt pattern on 9" Axle Housings are NOT universal. Please check before cutting or welding
We recommend the addition of our Axle Housing Inspection Hole Kit to allow for easy fluid level and ring gear visibility. Just select "With Inspection Hole Kit Installed" in the drop down menu above. The kit is also available in a DIY installation version (requiring drilling through the differential housing and welding on a threaded bung).
