Trail GearSKU: 300084-KIT



Rock Assault Nine Rear Axle Housing with bearing pockets 3.5 Inch x 1/4 Inch x 60 Inch Length WMS.

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 most applications. Designed for Wheel Mount Surfaces 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 Assault 9 Axle Housing to allow for the use of a 10 Inch 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 Assault 9 is the strongest on the market that we are backing the product with our legendary No Questions Asked Warranty. 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.
