4 Inch Lift Kit | Rear Springs | Ford F-250/f-350 Super Duty 4wd (1999-2004)

Built for Ford Super Duty 4WD owners who want a level stance with serious ground clearance, this 4-inch lift kit raises the front of your truck to match the rear for that aggressive, balanced look. Rough Country's dual-spring system lets you run 33–35-inch tires while maintaining ride quality and factory-like geometry — no sacrifice required.

What's included

• 4-inch front leaf springs (pair) — engineered specifically for the Super Duty front end to deliver smooth ride height without compromising suspension articulation.
• 4-inch rear leaf springs (pair) — matched rear springs keep your truck level and stable under load.
• N3 shock absorbers (pair, front and rear) — Rough Country's 10-stage variable high-pressure nitrogen-charged shocks with 18mm spring-loaded piston rods and 54mm bodies deliver confident off-road control and smooth highway manners.
• Box kit with sway bar drop brackets and track bar bracket — maintains proper suspension geometry and driveline angles after the lift to preserve factory-like ride quality.
• Universal U-bolt kits (qty 2) — secure the springs to your axles with premium fasteners.
