6 Inch Lift Kit | Gas | 4 Link | No Ovlds | C/o Vertex | Ford F-250/f-350 Super Duty (05-07)

Built for first-generation Super Duty owners who want a modern coilover conversion with ride height adjustability and killer geometry — this 6-inch 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with adjustable Vertex 2.5-inch monotube coilovers, giving you a 6-inch lift, proper caster correction through radius arm drop brackets, and the capability to run 35–37 inch tires. The monotube design with external reservoir delivers 56% greater fluid capacity than standard shocks, preserving factory handling and driveability while adding serious off-road damping control.

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

• 6in Up Arm Kit — fixed upper control arms engineered for the 4-Link conversion geometry.
• 6in Lower Arms — adjustable lower control arms allow fine-tuned caster and camber correction.
• Vertex 2.5 Adjustable Front Shocks (Left & Right, 4.5–6 inch) — nitrogen-charged monotube coilovers with 8-stage damping adjustment and external reservoir for superior ride quality and off-road control.
• Vertex 2.5 Rear Shocks (Pair, 6 inch) — matched rear coilovers maintain balanced suspension geometry front to rear.
• Radius Arm Drop Brackets — steel mounts that preserve proper caster angle, critical to maintaining factory handling characteristics.
• Add-A-Leaf — rear leaf spring add-on for load-carrying capacity and stance leveling.
• 3 Inch Block & U-Bolt Kit — rear suspension block and fasteners for rear lift geometry.
• Kit Box & Hardware — all brackets, fasteners, and installation components.

Important notes

• Does not fit dually models.
• Requires exhaust modification to clear the front driveshaft during installation.
• Installation involves cutting and drilling — an estimated 6–10 hours is recommended. Professional installation at Road Runner ensures proper alignment and caster setup.

Why customers pick this at Road Runner

• Caster correction is dialed in during installation — radius arm drop brackets maintain factory handling geometry, so your truck drives true after lift.
• Vertex coilovers are mounted and bench-tested by techs who perform these conversions every week — no guesswork on damping or ride height.
• Rough Country's limited lifetime replacement warranty is backed locally — any manufacturer defect is covered, and we honor it on the spot.
• Professional alignment performed in-house as part of every lift install — your suspension geometry is verified and corrected before you drive off.
• Exhaust modification managed in-house — we coordinate cutting and clearance so driveshaft and exhaust work together.
