Rough Country's 4.5-inch lift kit transforms your 2017-2022 F-250 or F-350 Super Duty diesel into a more capable, more aggressive truck without the headaches of a complex build. Lifted coil springs, track bar, sway bar drop brackets, and a set of application-valved shocks ship together in one kit, so everything needed to clear up to a 35-inch tire arrives in a single order. Bolt-on installation keeps the job accessible for a capable DIY installer with common hand tools.
Leveled stance, maintained geometry. The kit raises the front to match rear ride height, eliminating the factory nose-down rake. Radius arm drop brackets correct caster to factory specification after the lift, preserving straight-line stability and steering feel. A track bar and sway bar drop brackets keep suspension angles dialed in so the truck drives cleanly on the highway as well as off it.
Lifted coil springs built for loaded trucks. The front coil springs provide the lift without sacrificing load-carrying ability or introducing excessive harshness. Super Duty owners who tow and haul regularly will find the ride character remains composed rather than choppy.
Shock absorbers tuned for this application. Rough Country's N3 shocks ship as the base configuration, featuring 10-stage variable valving, high-pressure nitrogen charge, an 18mm spring-loaded piston rod, and a 54mm shock body that dissipates heat faster on extended off-road runs. Upgraded shock options including M1 monotube, V2 monotube, and Vertex reservoir units are available at configuration to match the intended use of the truck. A front driveshaft can also be added at checkout to address driveline angles after lifting.
Fabricated rear blocks for lasting strength. The rear lift blocks are fabricated steel rather than cast, which resists cracking under the cyclic loads that heavy-duty trucks generate when towing, hauling, or traversing rough terrain.
