Level up your Super Duty stance
Give your fifth-generation Ford F-250/F-350 Super Duty the aggressive lift it deserves with Rough Country's 4.5" suspension lift kit. This premium kit eliminates factory rake, delivers front-to-rear leveling, and increases ground clearance, resulting in a bold, commanding presence on and off the road.
Strength meets precision with tubular radius arms
Ditch the weak factory setup. This kit features high-clearance tubular radius arms with a beefy 2-inch outer diameter design engineered for superior strength, durability, and optimized suspension geometry. These arms bolt directly into factory mounts for a straightforward, secure installation without the need for drop brackets.
Engineered for ride quality
Lifted front coil springs raise your stance while maintaining a smooth, controlled ride. Designed to preserve factory-like angles, this system includes sway bar drop brackets and a track bar relocation bracket to ensure proper geometry and predictable handling across any terrain.
Durability where it counts
Heavy-duty fabricated rear blocks outperform standard cast blocks with enhanced strength and longevity. Anti-axle wrap blocks help eliminate unwanted movement under torque, preserving your factory ride quality even under load.
Customize your ride performance
Dial in your preferred ride feel with configurable shock options. Go with Rough Country's nitrogen-charged N3 shocks for balanced on-road comfort and trail performance, or upgrade to V2 monotube shocks for premium responsiveness and heat dissipation during demanding off-road conditions.
Quick, bolt-on installation
No cutting, no drilling, just a simple bolt-on setup that gets you back on the road fast. This kit clears up to a 35" tire with proper wheel backspacing, unlocking your ideal stance without the headache.
