4.5 Inch Lift Kit | Radius Arm | V2 | Diesel | Ford F-250/f-350 Super Duty (23-26)

Built for diesel Super Duty owners who want a commanding lift without factory rake, this 4.5" Suspension Lift Kit delivers front-to-rear leveling, increased ground clearance, and an aggressive stance on and off the road. Tubular radius arms with 2" outer diameter design maintain improved suspension geometry while bolting directly into factory mounts — no cutting or drilling required. Supports up to 35" tires with proper wheel backspacing.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

• Does NOT fit dually models.
• Supports up to 35" tires with proper wheel backspacing; verify offset and backspacing before tire selection.
