6 Inch Lift Kit | Vertex | Ford F-150 4wd (2015-2020)

Built for F-150 4WD owners who demand aggressive stance and trail-ready clearance, this 6-inch lift kit elevates your truck's capability and appearance. Gain up to 6 inches of ground clearance and the room to safely run 35-inch tires — all while preserving factory-like driveline angles and ride quality through engineered crossmembers, differential drop brackets, and a driveshaft spacer.

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

• Vertex 2.5" Adjustable Front Struts (left and right) — nitrogen-charged cartridges that deliver 6 inches of lift with the ability to fine-tune ride height and dampening for both on-road and off-road driving.
• Vertex 2.5" Rear Shocks (pair) — matched rear dampers that work with the anti-axle wrap blocks to level the truck and maintain stock ride quality under load.
• Lifted Front Knuckles — custom-engineered spindle carriers that provide the geometry correction needed to preserve caster and alignment after the 6-inch lift.
• Front and Rear Crossmembers — 1/4-inch plate steel fabricated frames that anchor the suspension and add structural support without compromising factory handling dynamics.
• Anti-Axle Wrap Rear Blocks — custom-designed lift blocks that prevent rear-axle wrap and binding, keeping your truck stable under acceleration and braking.
• Driveshaft Spacer, Differential Drop Brackets, Sway-Bar Drop Brackets, and Brake-Line Brackets — all geometry-correction hardware needed to maintain factory-correct angles and prevent drivetrain vibration or brake-line chafe.

Important notes

• This kit requires cutting and drilling for installation.
• Does NOT fit regular cab or standard cab F-150 models — extended and crew cabs only — due to pinion angle geometry that causes drivetrain vibrations in shorter wheelbase configurations.
• Factory wheel owners running this lift should stay at or below 11.5" tire width to avoid suspension bind and rubbing.
• Recommended tire range is 35"–37" for maximum tire clearance and balanced performance.
