Built for F-250/F-350 Super Duty owners who want 6 inches of lift without sacrificing factory handling — this 4-Link lift kit pairs a true 4-Link front suspension with adjustable lower control arms, radius arm drop brackets for proper caster geometry, and rear fabricated anti-wrap blocks to eliminate axle wrap and maintain ride quality. Run 35"–37" tires safely with level stance and improved ground clearance.

What's included

• 6.5 In Block U-Bolt Kit — secures the rear blocks to the axle housing with reinforced fasteners.
• Box Kit — structural reinforcement brackets for the frame and suspension mounting points.
• 4.5–6" Upper Arm Kit — fixed upper control arms engineered to maintain suspension geometry through the lift range.
• 4.5–6" Adjustable Lower Arms — allows fine-tuning of caster and camber after installation for factory-like handling.
• CV Front Driveshaft — diesel-rated driveshaft for proper CV joint angles and vibration-free operation at lifted height.
• Vertex 2.5 Front Shocks (qty 2) — nitrogen-charged dampers tuned for both highway comfort and off-road performance.
• Vertex 2.5 Rear Shocks (qty 2) — matched rear units for balanced suspension behavior across all terrain.
• 6" Coil Springs — lifted front coils that level the vehicle while preserving factory ride characteristics.
• Radius Arm Drop Brackets — allow proper caster alignment and prevent binding throughout suspension travel.
• Fabricated Anti-Wrap Rear Blocks — stronger than cast alternatives; special design eliminates axle wrap and binding during acceleration or towing.
• Stainless Steel Extended Brake Lines & Brackets — ensure brake system geometry remains correct after lift installation.
