About the 4.5 Inch Lift Kit | Radius Arms | Ford F-250/F-350 Super Duty 4WD…

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.

Rough Country Has You Covered: Every Rough Country 4.5" Suspension Lift Kit is backed by our Limited Lifetime Warranty, lift confidently and drive boldly.
