6 Inch Lift Kit | Diesel | C/o Vertex | Ford F-250/f-350 Super Duty (08-10)

Built for Ford Super Duty owners who want maximum ground clearance and tire capacity without sacrificing factory ride quality — this 6-inch coilover conversion lift kit replaces the factory independent coil setup with adjustable Vertex Coilovers, letting you run 35–37 inch tires while preserving proper suspension geometry through precision-fitted radius arm drop brackets.

What's included

• Vertex 2.5" adjustable front coilovers (pair) — nitrogen-charged, 8-stage adjustable shocks with monotube design and external reservoir for 56% greater fluid capacity than standard shocks, delivering optimal damping control and handling.
• Vertex 2.5" rear coilovers (pair) — matched to the front for balanced suspension geometry and consistent ride quality across the wheelbase.
• Radius arm drop brackets — precision-fit to factory mounts to maintain correct caster angle, ensuring factory-like handling and driveability after the lift.
• Add-A-Leaf — rear spring supplement for load-carrying capacity and proper ride height.
• 3-inch block and u-bolt kit — rear suspension block for additional ground clearance.
• Installation hardware and fasteners — all bolts, brackets, and mounting hardware needed to complete the conversion.

Important notes

• Does not fit dually models.
• If your vehicle is equipped with factory rear overload leafs, they must be removed before installation.
• Gas models may require exhaust modification to clear the front driveshaft.
• Installation requires cutting and drilling — plan 6–10 hours for completion.
