6 Inch Lift Kit | Diesel | 4 Link | M1 | Leaf Springs | Ford F-250/f-350 Super Duty (05-07)

Built for diesel F-250/F-350 Super Duty owners who want 6 inches of lift without sacrificing factory handling, this 4-Link suspension lift kit raises your truck while preserving the geometry that makes it drive straight and predictable. Rough Country engineered radius arm drop brackets that preserve caster angle — the critical factor in maintaining factory-like steering feel and tire wear after a lift. Accommodate tires up to 37 inches and gain the aggressive stance you're after, all through a 100% bolt-on install with no cutting or welding required.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• 6-inch upper arm kit — precision-fit brackets that bolt to factory mounts for straightforward installation and preserved suspension geometry.
• 6-inch lower control arms — adjustable at the axle to dial in proper caster angle after lift, ensuring stable steering and even tire wear.

• M1 Monotube shocks (pair) — valved for balanced on and off-road performance, absorbing bumps without compromise.

• Brake line relocation brackets — routes brake lines safely to clear the lifted suspension.
