4.5 Inch Lift Kit | Ovld | C/o Vertex | Ford F-250 Super Duty 4wd (15-16)

Built for F-250 Super Duty owners who want a commanding lift without sacrificing ride quality — this 4.5-inch coilover suspension lift kit replaces the factory independent coil setup with a massive 2.5-inch piston Vertex coilover system. You'll gain up to 37-inch tire clearance while maintaining factory-like suspension geometry through precision radius arm drop brackets.

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

• 6.5-inch block U-bolt kit — secures the rear axle housing with factory-strength fastening.
• Box kit (front) — structural support for the coilover conversion mounting points.
• 4.5-inch kit box (coilover conversion) — adapts the factory mounting to accept the new Vertex coilover system.
• Vertex 2.5-inch adjustable front shocks (left and right, 4.5–6-inch range) — nitrogen-charged, 8-stage adjustable monotube design with external reservoir for 56% greater fluid capacity than standard shocks; delivers balanced on-and-off-road performance.
• Vertex 2.5-inch rear shocks (pair, 6-inch) — matched rear coilovers with the same monotube, high-capacity design for coordinated damping control.

Important notes

• Does not fit F-350 models, gas engines, or dually configurations.
• Trucks equipped with a 2-piece rear driveshaft require a carrier-bearing drop bracket (sold separately).
• Installation requires cutting and drilling; plan 6–10 hours for completion.
• Radius arm drop brackets correct factory caster angles to preserve handling and driveability after the lift.
• Fabricated blocks offer superior strength and lifespan over cast alternatives; anti-axle-wrap design maintains stock ride quality.
