4.5 Inch Lift Kit | W/o Overloads | Vertex | Ford F-250/f-350 Super Duty (08-10)

Built for F-250 and F-350 Super Duty owners who want maximum ground clearance without compromising factory ride quality and handling. This 4.5-inch lift kit pairs coil springs engineered for diesel powertrains with precision-engineered blocks, drop brackets, and geometry-correcting components that preserve the Super Duty's OE caster angles and steering response. You'll clear 33–35-inch tires while maintaining factory driveline geometry.

What's included

• Vertex 2.5 FR 6 In Shocks (qty 2) — Front dampers valved for N3 series performance, balancing on-road comfort with off-road capability.
• Vertex 2.5 RR 6 In Shocks (qty 2) — Rear dampers matched to the front for consistent suspension response across the platform.
• 6.5in Block U-Bolt Kit — Fabricated rear blocks that are stronger and longer-lasting than cast alternatives, engineered to resist common lift block failure modes.
• 6 Inch Coil Box — Luxury-rate coil springs specifically tuned for diesel engine weight and load characteristics.
• Kit Box — All fasteners, brackets, and hardware needed for a complete installation.

Important notes

• This kit does NOT fit V-8 gas engine models or dually configurations. Confirm your engine type before ordering.
• V-10 gas engine models require exhaust modification to clear the front driveshaft.
• If your vehicle is equipped with rear overload leafs, they must be removed prior to installation.
• Steering stabilizer relocation bracket is included. For tires larger than 35 inches, a Rough Country single or dual stabilizer upgrade is recommended or required (37-inch tires mandate the dual unit).
• Radius arm drop brackets and track bar relocation bracket maintain proper caster and axle centering — critical to preserving factory handling and driveability.

• Geometry-corrected installation — our techs set caster, steering angles, and track bar position during every lift, so your truck handles like OE even after the lift.
• Rough Country lifetime warranty backed locally; any issue gets resolved right here.
• Same-day installation by technicians who perform Super Duty lifts every week — no guesswork, no comebacks.
