6 Inch Lift Kit | Diesel | No Ovld | M1 | Ford F-250 Super Duty 4wd (11-14)

Built for F-250 Super Duty diesel owners who want more ground clearance and better trail capability, this 6-inch lift kit levels your truck's stance while maintaining factory handling geometry. You'll gain up to 37-inch tire clearance and restore proper caster angles that keep your rig driving true on and off the road.

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 D-Coil springs — lifted coil springs engineered to raise your front end while maintaining suspension geometry and ride quality.
• Radius arm drop brackets — preserve factory caster angles for correct handling and driveability after the lift is installed.
• Fabricated anti-wrap rear blocks — stronger and longer-lasting than cast alternatives; specially designed geometry prevents axle wrap and binding under load.
• M1 MONOTUBE shock absorbers (front and rear pair) — nitrogen-charged N2.0 series shocks deliver balanced performance for highway driving and off-road use.
• Extended stainless-steel brake lines and brackets — ensure proper brake-line routing after the lift to maintain safe stopping power.
• Installation hardware kit — all fasteners and U-bolts needed for a complete bolt-on install.

Important notes

• This kit is designed for diesel F-250 Super Duty models without rear factory contact overload springs (2011–2014, 4WD). It does NOT fit F-350 models, dually models, or gas-engine F-250s.
• Maximum tire size supported is 37 inches. Staying within the 35–37 inch range preserves drivetrain geometry and suspension performance.
• Fabricated blocks and anti-wrap design eliminate common lift-block problems — your rear suspension will maintain stock ride quality without binding.
