6 Inch Lift Kit | 4-Link | OVLD | M1 | Ford F-250/F-350 Super Duty 4WD (17-22)

Take your Ford F-250/F-350 Super Duty 4WD to new heights with Rough Country’s 6-Inch Lift Kit (4-Link) for 2017–2022. This is not a simple spacer lift—it’s a complete suspension upgrade that unlocks substantial wheel travel, enhanced stability, and an intentionally aggressive stance, all while preserving confident on-road manners.

What sets this kit apart

• True 4-Link suspension replaces fragile factory arms with a robust 4-Link setup that enhances articulation and control across rugged terrain, so you can tackle uneven trails with less bind and more predictability.
• Fixed upper arms + adjustable lower control arms optimize geometry and alignment, delivering consistent handling as the suspension flexes through rock-crawling, washboard, or high-speed whoops.
• Radius arm drop brackets maintain proper caster and steering geometry, a critical factor for factory-like stability at highway speeds and when towing or carrying heavy loads.
• Anti-wrap rear blocks prevent axle wrap and binding under heavy acceleration, keeping the drivetrain planted and reducing drivetrain stress on rough terrain.
• Stainless steel extended brake lines and brackets ensure safe, reliable braking performance with the lifted height and longer travel every time you hit the brakes.
• N2.0 nitrogen-charged shocks deliver a balanced ride that soaks up whoops off-road while remaining composed and smooth on the highway—road comfort without sacrificing off-road grip.
• All-in-one package includes lifted coil springs, radius arm drop brackets, and all necessary hardware, making installation more straightforward and predictable.
• Rough Country Lifetime Replacement Warranty quiets worry, so you can push the truck harder with confidence.

What’s included

• Lifted coil springs
• Radius arm drop brackets
• Ultra-durable fabricated anti-wrap rear blocks
• Stainless steel extended brake lines and brackets
• N2.0 nitrogen-charged shock absorbers
• All necessary mounting hardware and instructions

Performance and ride quality

With a 6-inch lift, you’ll gain noticeable ground clearance for challenging trails and more room for larger, capable tires. The combination of a 4-Link setup and caster-preserving radius arm drops keeps steering predictable as you traverse rutted lanes or slow-speed rock yards. Expect improved wheel travel, reduced axle binding, and a more planted feel when you’re maneuvering over obstacles. The N2.0 shocks are tuned to balance off-road damping with highway comfort, so daily driving stays smooth while off-road sessions feel controlled and confident.

Who this kit is for

• Ford F-250/F-350 Super Duty 4WD owners looking for substantial ground clearance and enhanced off-road capability without sacrificing highway stability.
• Adventurous drivers who routinely tackle washboards, rock fields, desert trails, or towing scenarios that demand better suspension articulation and reliability.
• Trucks used as work vehicles or overland rigs where durability, long-term warranty support, and predictable performance matter most.

How this kit compares to alternatives

Compared to spacer or coilover-only lifts, this 6-inch 4-Link system actively manages suspension geometry, caster settings, and anti-wrap behavior. The result is superior on-trail traction, reduced drivetrain strain, and more controlled handling at highway speeds—especially when carrying payloads or towing heavy trailers. The integrated hardware and quality components like stainless brake lines and nitrogen-charged shocks provide a more complete, reliable upgrade than piecemeal kits.

Installation and care

This is a comprehensive lift upgrade that benefits from professional installation or a qualified shop with experience in heavy-duty 4x4 suspensions. After installation, alignment is essential to maximize the benefits of restored geometry and caster. Regular inspection of suspension joints and bolts is recommended to maintain peak performance over time.
