About this kit
6-Inch Super Duty Lift Kit, N3 Shocks, 4.5-In Blocks & U-Bolts, fitment-checked
One of Rough Country's 6-inch Super Duty kits, and the kit contents are what separate them: this one carries N3 series shocks with the 4.5-inch block and U-bolt set listed without overloads. Vehicle coverage and exclusions are common to the whole group.
A third axis runs through this group beyond the damper and the block: some kits add a universal U-bolt kit and some do not. This one does, on top of N3 series shocks and the 4.5-inch no-overload block set. That extra hardware is the reason it weighs more than the otherwise identical build without it. A 6-inch coil box and front CV drive shaft are also included. Shipping weight: 254.35 lb.
