Built for F-150 4WD owners who want aggressive stance and tire clearance without losing factory handling geometry, this 6-inch Rough Country lift kit delivers the ground clearance to run up to 37-inch tires while preserving track width consistency and steering feel. The kit pairs lifted knuckles and M1 monotube struts with fabricated rear blocks engineered to eliminate axle wrap — so you get both the look and the composed ride.

What's included
- M1 Loaded Strut Pair — Nitrogen-charged premium monotube struts paired with spacers for the front 6-inch lift and optimized suspension geometry.
- M1 Monotube Shock Pair — Rear shocks tuned for control and ride quality on and off the trail.
- 6-inch Rear Block and U-Bolt Box — Fabricated steel blocks engineered with anti-axle-wrap geometry to preserve stock ride characteristics while lifting the rear axle.
- Lifted Knuckles (Driver and Passenger) — Maintain factory steering geometry and track width while providing the necessary caster correction for the 6-inch front lift.
- Front and Rear Crossmembers — 1/4-inch plate steel construction for added strength and proper suspension-component geometry.
- Differential Drop Bracket, Sway-Bar Drop Bracket, and Brake-Line Brackets — Ensure all driveline and brake components stay at factory angles after the lift.
Important notes
- Does NOT fit 2004 Heritage models or trucks equipped with the Heavy Duty Payload Package (seven-lug models).
