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 (Choice of tubing 3” ¼” Wall, or 3” 3/8” Wall)
• Unit Hubs (lug nuts included)
• Unit Bearing Pockets
• Rock Assault 9” Seal Housing Kit.
• Rock Assault 9™ Fully Loaded Brake Kit

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.

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.
