6 Inch Lift Kit | Diesel | 4 Link | No Ovlds | Ford F-250/f-350 Super Duty (05-07)

Built for diesel Super Duty owners who want a 6-inch lift without sacrificing factory geometry, this 4-Link Suspension Lift Kit adds aggressive stance and ground clearance while preserving the driveline angles that keep your truck handling like it should. The 35–37" tire range pairs perfectly with the increased clearance, and radius arm drop brackets ensure proper caster correction for maintained factory handling.

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

• N3 Shock Kit — Application-valved shocks tuned for balanced performance on and off-road, delivering factory-quality ride without the factory ride height.
• 6-Inch Upper Arm Kit — Maintains suspension geometry as the vehicle rises, preserving handling and reducing component wear.
• 6-Inch Lower Arms with Caster Adjustment — Allows fine-tuning of caster angle after install to preserve factory handling characteristics and tire life.
• 6-Inch D-Coil Springs — Lifted coil springs engineered to work in concert with the shock package for balanced on and off-road ride quality.
• 3-Inch Block & U-Bolt Kit — Rear spring support that levels the truck with the front lift, maintaining proper weight distribution.
• Add-A-Leaf — Secondary rear spring element for additional load-carrying capacity and improved ride under payload.
• Radius Arm Drop Brackets, Track Bar Relocation, Drop Pitman Arm, and Brake Line Brackets — Complete geometry correction package that ensures all suspension angles stay as close to factory as possible, minimizing modification to driveline components and keeping alignment stable.

Important notes

• This kit is engineered for diesel F-250/F-350 Super Duty (2005–2007) only — does not fit gas engine models.
• Not compatible with dually configurations.
• Not compatible with factory rear overload springs — those must be removed before installation.
