4.5 Inch Lift Kit | FR D/S | C/O Vertex | Ford F-250/F-350 Super Duty (17-22)

Elevate your Ford F-250/F-350 Super Duty (2017–2022) with Rough Country’s 4.5-inch Coilover Suspension Lift Kit, a true leap in capability that preserves ride quality while delivering serious off-road potential. This FR D/S kit features a Vertex coilover system designed to replace the factory setup with a robust, high-performance alternative that changes how your truck handles both daily driving and tough trails.

• 4.5-inch lift height delivers substantial ground clearance to tackle rough terrain while providing room for up to 35-inch tires, transforming the stance and capability of your Super Duty.
• Vertex Coilovers replace the stock independent coil setup with a 2.5-inch piston, nitrogen-charged coilover system. The monotube design includes an external reservoir for increased oil capacity and damping sensitivity, giving you precise control through demanding terrain.
• Enhanced durability and geometry features ultra-durable radius arm drop brackets that bolt into factory mounts, preserving factory angles and steering geometry for a more predictable, confidence-inspiring ride.
• Superior damping and fluid capacity with Rough Country’s monotube Vertex shocks paired with a design that delivers roughly 56% more fluid capacity than typical reservoir shock setups—meaning cooler operation, more consistent damping, and longer life under hard use.
• Factory-like ride on and off the trail despite the lift, thanks to the combination of geometry preservation and high-performance Vertex dampers, which balance comfort with controlled handling in all conditions.

This kit is engineered as an all-inclusive transformation for Ford F-250/F-350 Super Duty owners who want serious capability without sacrificing daily usability. It enables aggressive off-road performance while maintaining a smooth, road-friendly feel that you’ll notice every time you hit the highway or backroads.

Installation notes — this upgrade requires cutting and drilling for proper fitment. Plan for a typical installation window of 6–10 hours, and you can complete the project at home with basic shop tools. The payoff is a dramatically improved suspension geometry, stronger shock absorption, and a stance that commands attention.

Warranty and peace of mind — Rough Country backs this lift with its Limited Lifetime Replacement Warranty, giving you confidence in the durability and workmanship of the components long after installation.

Who this is for — ideal for truck enthusiasts who want to conquer rough terrain, carry heavier loads, or simply achieve a tougher, more capable appearance. If you’re upgrading from stock or a smaller lift, this 4.5-inch kit with Vertex coilovers is designed to deliver a noticeable upgrade in traction, control, and comfort over mixed terrain, without compromising everyday usability.

Choose the 4.5 Inch Lift Kit with Vertex coilovers for the Ford F-250/F-350 Super Duty (2017–2022) when you crave a purposeful, capable truck that performs exceptionally in both on-road comfort and off-road dominance. Your vehicle will sit taller, handle tougher terrain with ease, and maintain the ride quality you expect from a factory-calibrated suspension—only now it’s tuned for the adventures you actually pursue.
