6 Inch Lift Kit | No Ovlds | C/o V2 | Ford F-250/f-350 Super Duty 4wd (17-22)

Built for Ford Super Duty owners who want to run 35–37 inch tires while preserving factory ride quality, this 6-inch coilover conversion lift kit replaces the factory independent coil-shock setup with Rough Country's durable Vertex 2.5-inch monotube coilovers. The radius arm drop brackets correct caster geometry, keeping handling smooth and driveability factory-like — a critical detail that separates this kit from casting-prone alternatives.

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" Lift Kit Box — structural frame and mounting hardware engineered for the fourth-generation Super Duty 4WD platform.
• 4.5 In Block U-Bolt Kit (No Overloads) — fabricated rear blocks that are stronger and longer-lasting than cast alternatives, with anti-axle wrap geometry to maintain stock ride quality.
• 6" Coilover Conversion Kit Box — hardware and brackets for the transition from factory independent coil-shock to aftermarket coilover suspension.
• Vertex 2.5 Adjustable Front Coilovers (Left and Right, 4.5–6 inch) — nitrogen-charged, 8-stage adjustable shocks with monotube design, external reservoir, and 56% greater fluid capacity than average reservoir shocks for superior damping control.
• V2 Monotube Shock Pair — paired monotube dampers optimized for the coilover system.
• Radius Arm Drop Brackets — precision-fit brackets that bolt to factory mounts and correct caster angle to preserve factory handling and driveability.
• Transfer Case Clocking Kit — specialized hardware for proper transfer-case geometry during the lift conversion.
• Universal U-Bolt Kit (3/4 x 4, 1 x 1/2 inch) — OEM-grade fasteners for secure suspension attachment.

Important notes
