4.5 Inch Lift Kit | No Ovld | C/o V2 | Ford F-250 Super Duty 4wd (15-16)

Built for Ford F-250 Super Duty owners who want 4.5 inches of lift without sacrificing factory ride quality — this coilover conversion kit swaps the OE independent coil setup for Rough Country's Vertex 2.5-inch adjustable coilovers, opening up clearance for 33–35 inch tires while preserving suspension geometry through precision-fit 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

• 4.5 In Block U-Bolt Kit (No Overloads) — fabricated steel rear blocks engineered with anti-axle wrap geometry to maintain stock ride quality and eliminate common lift-block issues.
• Box Kit (Front) — mounting brackets and hardware for the front conversion assembly.
• 4.5" Coilover Conversion Box — complete front conversion system for the coilover swap.
• Vertex 2.5 Adj FR Coilovers (Pair) — nitrogen-charged, 8-stage adjustable monotube shocks with external reservoir, 56% greater fluid capacity than standard designs, paired with precision-fit radius arm drop brackets for proper caster correction and factory-like suspension angles.
• V2 Monotube Shock Pair (Rear) — application-valved N2.0 series absorbers tuned for balanced on and off-road performance.

Important notes

• Does NOT fit F-350 models, gas engine F-250s, or dually configurations.
• Trucks equipped with a 2-piece rear driveshaft require an additional carrier-bearing drop bracket.
• Installation requires cutting and drilling; plan 6–10 hours for completion.

Why customers pick this at Road Runner

• Radius arm drop brackets maintain proper caster — critical for factory handling and driveability after the lift.
• Coilover conversion preserves suspension geometry better than traditional block lifts, keeping your truck level and balanced.
• Rough Country's lifetime warranty backed locally — warranty service handled by the techs who install your kit.
• Professionally installed by technicians who perform these conversions every week — no guesswork on cutting angles or brake-line placement.
• Alignment performed in-house as part of every lift install, so your truck drives true from day one.
