6-Inch Super Duty Lift Kit, N3 Shocks, 4.5-In Blocks, 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.

Rough Country builds this 6-inch Super Duty lift in sixteen combinations, and the box is the only thing that tells them apart. This one pairs N3 series shocks with the 4.5-inch block and U-bolt set, the version listed without overloads, alongside a 6-inch coil box and a front CV drive shaft. Pick the damper first and the block second. The truck list is identical across all sixteen. Shipping weight: 228.35 lb.

Priced components are sold separately here, so a worn shock or arm can be replaced on its own later.

Rough Country shares subassemblies across kits, so individual package labels can carry broader application ranges. The complete 43731 kit fits the vehicles shown in the fitment section above.
