6 Inch Lift Kit | Diesel | Ford F-250/f-350 Super Duty 4wd (2005-2007)

Built for diesel Super Duty owners who want a commanding 6-inch lift without sacrificing handling or driveability — this coil-spring lift kit raises your F-250 or F-350 while leveling front-to-rear geometry and preserving factory caster angles. You'll clear 35–37-inch tires and gain the ground clearance you need for serious off-road or work duty.

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 engineered for balanced performance on and off-road, matched to your diesel Super Duty's suspension demands.
• 6-Inch D-Coil Springs — luxury-ride coil springs designed specifically for diesel motors, matching OE spring rates.
• Radius Arm Drop Brackets — maintain factory caster angles for proper steering geometry and driveability.
• Track Bar Relocation Bracket — centers the axle and matches steering angles created by the drop pitman arm.
• Add-A-Leaf — reinforces rear spring capacity under the lift load.
• 3-Inch Block and U-Bolt Kit — rear suspension blocks and fasteners for proper ride height.
• Steering Stabilizer Relocation Bracket — maintains steering control as ride height changes.

Important notes

• This kit is designed for diesel models only — does not fit gas-engine Super Duties.
• Does not fit dually models.
• If your vehicle is equipped with factory rear overload leafs, they must be removed before installation.
• Steering stabilizer upgrades recommended: a Rough Country single stabilizer suits 35–36-inch tires; a dual stabilizer is required when running 37-inch tires.
