Transform your fourth-gen Ford Super Duty with Rough Country's 3-inch Coilover Conversion Kit, swapping the factory setup for massive 2.5-inch Vertex Coilovers with external reservoirs for 56% more fluid capacity and superior damping. The ultra-durable radius arm drop brackets bolt right into factory mounts, keeping your geometry dialed for smooth, factory-like handling while clearing up to 35-inch tires.

This all-inclusive kit levels the front with the rear, boosts ground clearance, and comes with fabricated blocks that outlast cast alternatives—all backed by a limited lifetime replacement warranty.
