6 Inch Lift Kit | 4-link | No Ovld | D/s | Vertex | Ford F-250/f-350 Super Duty (17-22)

Built for F-250 Super Duty diesel owners who want serious ground clearance and controlled suspension geometry, this 6-inch 4-Link lift kit replaces your factory control arms with a fixed upper-arm and adjustable lower-arm setup, paired with Vertex shocks and fabricated anti-wrap rear blocks. You'll gain the clearance for 35"–37" tires while maintaining proper caster angle and factory-like handling.

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

• Box Kit — Structural base for the 4-Link conversion on your F-250/F-350 Super Duty.
• Upper Arm Kit — Fixed upper control arms engineered for the 4.5"–6" lift range, maintaining proper suspension geometry.
• Lower Arms — Adjustable lower control arms allow fine-tuned caster correction after installation.
• Block U-Bolt Kit (No Overloads) — Fabricated rear lift blocks stronger and more durable than cast units, with anti-axle wrap design to eliminate binding and preserve ride quality.
• CV Drive Shaft (Front, Diesel) — Updated front driveshaft accommodates the increased suspension angle and maintains proper driveline geometry.
• Vertex 2.5 FR Shocks (qty 2) — Nitrogen-charged front shocks tuned for balanced on- and off-road performance.
• Vertex 2.5 RR Shocks (qty 2) — Nitrogen-charged rear shocks that work with the anti-wrap blocks to maintain stock ride comfort while handling the lifted chassis.
