Bold stance, better clearance
Transform your Ford with Rough Country's 4" suspension lift kit, delivering a more aggressive, leveled look from front to rear. This system eliminates the factory rake for a balanced stance while improving ground clearance to take on uneven terrain and off-road challenges with confidence.

Performance-driven components
The kit includes a set of durable front coil springs for enhanced ride height without sacrificing comfort or performance. Application-specific 7-degree c-bushings and a track bar drop bracket maintain proper geometry and alignment, ensuring a factory-like ride quality even after lifting.

Premium N3 shock absorbers
This kit features Rough Country's nitrogen-charged N3 shocks, precision-tuned with a 10-stage variable valving system, 18mm piston rods, and fast-cooling 54mm shock bodies for enhanced off-road handling and smooth highway ride quality.

Ready for 35-inch tires
Gain the clearance needed to run up to 35" tires, giving your truck a more aggressive profile and increased off-road capability, all with proper wheel backspacing.

Built to last
Backed by Rough Country's limited lifetime replacement warranty, this 4" Ford suspension lift kit combines rugged durability with confidence-inspiring performance, on and off the road.
