6 Inch Lift Kit | 4-Link | OVLD | Ford F-250/F-350 Super Duty 4WD (2017-2022)

Take your Ford F-250/F-350 Super Duty 4WD to new heights with Rough Country’s 6-Inch Lift Kit, designed around a 4-Link setup that delivers more wheel travel, sharper handling, and bold ground clearance. By replacing the factory arms with a durable four-link system, this kit unlocks true off-road potential while preserving confident on-road feel.

Why this 4-Link kit stands out

The heart of the design is a combination of fixed upper arms and adjustable lower control arms that let you dial in precise geometry for your specific driving style. Paired with radius arm drop brackets, the system maintains proper caster settings, which translates to predictable steering, stable highway performance, and improved steering feedback on rough trails. The forged, purpose-built components are matched to deliver consistent durability under harsh terrain, heavy loads, and long-days on the trail.

What’s included and how it works

• 6-inch front lift springs to increase ground clearance and accommodate larger tires
• 4-Link arms with fixed upper arms and adjustable lower arms for tunable geometry
• Radius arm drop brackets to preserve caster and maintain factory-like handling
• Fabricated anti-wrap rear blocks to prevent axle wrap and binding
• Stainless steel extended brake lines and brake line brackets for reliable braking travel at height
• Nitrogen-charged N2.0 shock absorbers to balance off-road capability with highway smoothness
• All necessary components included to install and set up the lift

Performance and use cases

This kit is ideal for enamel-on-rough-trail explorers, weekend warriors, and work trucks that demand both off-road capability and dependable highway manners.
