6 Inch Lift Kit | Diesel | 4 Link | Vertex | Ford F-250/f-350 Super Duty (05-07)

Built for diesel F-250/F-350 Super Duty owners who want 6 inches of lift without sacrificing factory geometry, this 4-Link suspension kit from Rough Country delivers aggressive ground clearance while preserving the driveline angles that keep your truck handling like stock. Radius arm drop brackets maintain proper caster, and the adjustable lower control arms let you fine-tune your setup for balanced on and off-road performance. You'll fit 35–37 inch tires comfortably.

What's included

• 6-inch Up Arm Kit — precision-engineered upper control arms that bolt directly to factory mounts for a cleaner, faster install.
• 6-inch Lower Arms with caster adjustment — allow fine-tuning of suspension geometry after lift to maintain factory handling.
• Vertex 2.5 FR and RR shocks — four valved N3 series absorbers tuned for balanced on and off-road ride quality and daily-driver comfort.
• 6-inch D-Coil springs — lift the rear and maintain proper ride height across load cycles.
• 3-inch rear block and U-bolt kit — adds additional rear clearance and supports increased suspension travel.
