The Rock Assault 9 Rear Roller Kit is now available. Get started on your build, or upgrade with greater savings. We have redesigned the Rock Assault 9 Axle Housing to allow for the use of both a 9.0 Inch and 10.0 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.
