Rock Assaultª 9 Rear Axle Housing
The Rock Assaultª 9 is now available as a complete welded assembly from flange to flange including the Unit Bearing Pockets. The new Rock Assaultª 9 is available in 3 great sizes to fit most 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.
Trail-Gear went one step further, redesigning the Rock Assaultª 9 Axle Housing to allow for the use of a 10" differential! This will give you the option to create an even stronger axle and to give you that piece of mind knowing you have the strongest axle under your rig.
We are so confident our Rock Assaultª 9 is the strongest on the market that we are backing the product with our legendary No Questions Asked Warranty.
Now Available in 3.5" O.D. axle tubing.
