6 Inch Lift Kit | 4-link | No Ovld | Vertex | Ford F-250 Super Duty (11-14)

Built for F-250 Super Duty owners who want maximum ground clearance without sacrificing factory handling — this 6-inch 4-Link lift kit replaces your factory radius arms with a custom geometry setup that keeps proper caster angles while supporting 35"–37" tires. You get travel, clearance, and the aggressive stance without the driveline geometry headaches.

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

• Block U-Bolt Kit (No Overloads) — fabricated blocks that replace factory equipment with stronger, longer-lasting components designed to prevent axle wrap and binding.
• Box Kit — mounting structure that ties the rear suspension geometry into the frame for consistent load distribution.
• 6" Upper Arm Kit — fixed upper control arms positioned to maintain proper caster and suspension geometry at full lift height.
• 6" Lower Arms — adjustable lower control arms that let your technician dial in caster correction during installation for factory handling feel.
• Vertex 2.5 Front Shocks (qty 2) — nitrogen-charged N2.0 series absorbers tuned for balanced on and off-road performance.
• Vertex 2.5 Rear Shocks (qty 2) — matched N2.0 dampening for smooth highway ride and controlled off-road articulation.
• 6" Coil Springs — lifted springs that work with the new arm geometry to deliver the full 6 inches of height.
• Radius Arm Drop Brackets and Extended Brake Lines — critical geometry and hydraulic components that allow proper caster setting and ensure your brakes function correctly at lift height.

Important notes

• Kit is designed for 2011–2014 F-250 Super Duty models without rear factory contact overload springs. Does not fit F-350, dually, or gas-engine models.
• Proper caster correction through radius arm drop brackets is essential to maintain factory handling — this is set during professional installation.
• Fabricated anti-wrap rear blocks replace the factory lift block and are engineered to eliminate common binding and axle-wrap issues.

Why customers pick this at Road Runner

• Radius arm drop brackets and adjustable lower control arms allow our technicians to achieve proper caster angles — corrected geometry means your truck handles like it did stock, just taller.

• Our techs install these kits every week; they know the geometry inside out and perform alignment in-house as part of every lift installation.
• Nitrogen-charged Vertex shocks tuned for your truck mean you're not choosing between highway comfort and trail performance — you get both.
