6 Inch Lift Kit |4-link | No Ovld | Vertex | Ford F-250 Super Duty 4wd (15-16)

Built for F-250 Super Duty owners who demand serious lift with factory-level handling — this 6-inch 4-Link lift kit replaces your factory control arms with Rough Country's fixed upper arms and adjustable lowers, then adds lifted coil springs, radius arm drop brackets, and anti-wrap rear blocks. You'll gain 6 inches of ground clearance, properly corrected caster geometry, and the ability to fit 35"–37" tires while preserving the truck's drivability and ride quality.

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 rear blocks that eliminate axle wrap while maintaining stock ride quality — stronger and longer-lasting than cast alternatives.
• 6" Upper Arm Kit — Rigid fixed upper control arms that maintain precise geometry under load.
• 6" Lower Arms — Adjustable lower control arms that allow fine-tuning of suspension geometry during installation.
• 589 Box Kit — Structural reinforcement specific to your model year.
• 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 rear dampers for consistent suspension response.
• 6" Lifted Coil Spring — Front spring that works with the radius arm drop brackets to achieve proper caster correction.
• Radius Arm Drop Brackets — Set the correct caster angle to preserve factory handling and driveability — critical to maintaining steering feel and tire wear.
• Extended Stainless Steel Brake Lines — Prevent tension and damage as the suspension articulates through its new range of travel.

Important notes
