Rough Country Rear Block & U-Bolt Lift Kit – Add Rear Height & Eliminate Sag

If the rear of your Ford F-150 or Lightning is sagging or needs a bit of extra height, this kit from Rough Country delivers the reliable solution you’ve been looking for. Whether you're hauling, towing, or just trying to level out your suspension, this rear block and U-bolt kit restores ride height and reduces driveline stress for a better overall driving experience.

Unlike weak cast blocks, these fiberglass-reinforced nylon blocks are built for durability and tapered to help correct pinion angles. The included U-bolts feature a corrosion-resistant black e-coating and extended thread length to ensure a secure, lasting installation.
