The Rock Assault 9 Rear Roller Kit is now available. Get started on your build, or upgrade with greater savings.
Roller Kits come with:

• Rock Assault 9 Axle Housing
• Unit Hubs (lug nuts included)
• Unit Bearing Pockets
• Rock Assault 9 inch Seal Housing Kit.
• Rock Assault 9 inch Fully Loaded Brake Kit

We also redesigned the Rock Assault 9 Axle Housing to allow for the use of both a 9 inch and 10 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.

An optional 1.5 inch diameter inspection hole kit can be installed to provide quick access for ring gear inspection and fluid filling. The threaded aluminum inspection cap uses a rubber O-ring for a tight seal.

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.
