6 Inch Lift Kit | 4-Link | D/S | Vertex | Ford F-250/F-350 Super Duty (17-22)

Elevate your Ford F-250 or F-350 Super Duty with Vertex’s rugged 6-inch 4-Link lift kit. Designed to maximize travel and improve on-road and off-road handling, this system transforms your truck’s stance and capability without compromising factory geometry. By replacing the factory arms with a robust 4-Link setup, you gain meaningful articulation, better control, and a bold, aggressive profile that turns heads wherever you go.

What makes this 4-Link kit different

• 4-Link suspension design replaces the stock arms with a purpose-built 4-Link layout for improved axle control, better traction, and enhanced ride quality over rough terrain.
• Fixed upper arms + adjustable lower arms ensure precise alignment and easy fine-tuning of pinion angle and caster for dependable street manners and confident off-road performance.
• Radius arm drop brackets preserve factory geometry and caster settings, which helps maintain predictable steering and steering feedback after the lift.
• Heavy-duty components include lifted coil springs, ultra-durable fabricated anti-wrap rear blocks, and stainless steel extended brake lines with brackets to complete the install and maintain brake feel at height.
• Nitrogen-charged N2.0 shocks deliver a balanced blend of off-road compliance and highway comfort, reducing fade and preserving control as terrain changes beneath you.
• Lifetime replacement warranty provides long-term peace of mind, so you can push your truck harder with confidence.

Why Vertex 4-Link delivers real benefits

• Greater travel, better articulation means plush ride over whoops, whoa-worthy rocky sections, and rutted trails without losing traction.
• Improved ground clearance lets you fit larger tires or clear obstacles that would previously pinch the undercarriage, expanding your adventure envelope.
• Enhanced highway stability thanks to calculated caster and geometry control, so your daily drive remains predictable and safe at speed.
• Reduced axle wrap and binding with purpose-built anti-wrap components, keeping drivetrain angles stable under power and during articulation.
• Seamless integration with factory braking and steering systems through extended lines and properly engineered brackets, preserving OEM feel and reliability.
