Product Description
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. Rear Lifted Leaf Springs for Strength and Support: Engineered for dependability, the included rear leaf springs are double-tapered and feature Teflon pad inserts to improve ride comfort while offering consistent lift and added load support. 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.
