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

Built for Super Duty owners who want a commanding 6-inch lift with factory-corrected geometry and tire clearance for 35–37 inch rubber. This kit pairs OE-rate coil springs tuned for gas motors with caster-correction radius arm brackets, a track bar relocation system, and application-valved N3 shocks — everything needed to raise your F-250 or F-350, level the stance, and preserve the truck's stock handling and driveability.

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 absorbers engineered for balanced on and off-road performance on your Super Duty.

Important notes

• Does not fit dually configurations.
• If your truck is equipped with factory rear overload leafs, they must be removed before installation.
• Steering stabilizer upgrade recommended with 35–37 inch tires; a dual stabilizer is required if running 37 inch tires.
