Has the rear of your vehicle started to sag, or are you looking to add a bit of lift height? Whatever the case maybe we have you covered at Rough Country. Upgrade your rear suspension with Rough Country's vehicle-specific block and u-bolt kit! Rough Country's rear block and u-bolt kits provide a simple remedy to an age-old problem that simply happens over the span of your vehicle lift. Each kit offers two rear blocks that are tapered to reduce driveline angles, and are much stronger than the standard cast block option. These heavy-duty replacements feature a single pin measuring in a 9/16-inch to snuggle fit into your factory axle pad. Also included is a set of e-coated corrosion-resistant steel u-bolts. Our u-bolts offer four inches of thread ensuring that you have plenty of length to securely install this kit to the rear of your vehicle in no time flat. Best of all, Rough Country's vehicle-specific kits are backed by Rough Country's Satisfaction Guarantee!
