6 Inch Lift Kit | Diesel | 4 Link | Vertex | Ford F-250/f-350 Super Duty (08-10)

Built for Ford F-250/F-350 Super Duty diesel owners who want 6 inches of lift without sacrificing factory-like handling, this Rough Country 4-Link Suspension Lift System combines aggressive ground clearance with precision geometry correction. The radius arm drop brackets maintain proper caster angles — crucial for preserving factory drivability — while the adjustable lower control arms let you dial in suspension geometry precisely. Supports 35"–37" tires.
