4.5 Inch Lift Kit | R/a | C/o Vertex | Ford F-250/f-350 Super Duty (23-26)

Built for fifth-generation Ford Super Duty owners who demand adjustable ride height, superior handling, and up to 35-inch tire clearance without sacrificing everyday comfort. This 4.5-inch coilover lift kit combines fully adjustable Vertex 2.5-inch monotube shocks with tubular radius arms and heavy-duty fabricated blocks to level the truck front-to-rear, correct caster geometry, and preserve factory-like suspension angles — all while eliminating axle wrap.

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

• 4.5 In Block U-Bolt Kit — Heavy-duty fabricated rear lift blocks engineered to outperform cast alternatives and resist axle wrap while preserving factory ride quality.

• 4.5"–6" Radius Arm Kit — Tubular radius arms with 2-inch outer diameter, precision-fit to OEM mounts, maintaining proper caster correction and factory-like suspension geometry.
• Radius Arm Pass & Driver Upgrade Boxes — Reinforced radius arm assemblies for both sides, ensuring durability and consistent suspension performance across the front axle.
• Vertex 2.5" Adjustable Front Coilovers (pair) — Nitrogen-charged, 8-stage adjustable monotube shocks with external reservoirs offering 56% more fluid capacity for cooler, more consistent performance and fine-tuned ride height.

• V2 Monotube Shock Pair — Dual secondary front shocks that enhance stability, control, and damping across varied terrain and driving conditions.

Important notes

• This kit does NOT fit models equipped with a gas engine — diesel Super Duty only due to motor-weight variances.
• Does NOT fit models equipped with the Tremor Off-Road Package, which come with approximately 1.5 inches of factory lift.
• Does NOT fit dually models.
• Front-to-rear leveling corrects factory rake, aligning front suspension height with the rear for a more aggressive, balanced stance.
• Precision caster correction via tubular radius arms preserves factory-like handling and steering response.
