4.5 Inch Lift Kit | FR D/S | C/O V2 | Ford F-250/F-350 Super Duty (17-22)

Raise your 2017–2022 Ford F-250/F-350 Super Duty to new heights with Rough Country’s 4.5-inch Coilover Suspension Lift Kit (FR D/S, C/O V2). This all-in-one upgrade transforms your truck’s stance and off-road capability while preserving the smooth, confident highway ride you expect from a modern Super Duty. With room for up to 35-inch tires, you’ll conquer rugged terrain without sacrificing daily drivability.

Why this kit stands apart

• Vertex Coilover suspension — Replaces the factory coil setup with a massive 2.5-inch piston, nitrogen-charged Vertex Coilover. The monotube design features an external reservoir that significantly boosts oil capacity and damping sensitivity for consistent performance across conditions.
• Unmatched fluid capacity — Rough Country’s 2.5-inch piston design delivers roughly 56% more fluid capacity than the average reservoir shock, providing smoother damping and greater resistance to fade on demanding terrain.
• Geometry that stays true — Precision-fit radius arm drop brackets bolt into factory mounts, preserving factory-like angles and keeping suspension geometry aligned with the vehicle’s original design. That means improved control, steering feel, and reduced wear compared to kits that alter angles dramatically.
• Comprehensive, ready-to-build kit — Everything needed for a total transformation is included, allowing you to upgrade without hunting for missing parts or incompatible components.
• Designed for real-world use — Upgraded damping and height give you confidence from the trail to the highway, with tire clearance for up to 35-inch tires for a bold, capable look and improved ground clearance.

What you get and how it helps

• 4.5-inch lift height dramatically increases ground clearance for off-road travel and allows larger tires without compromising stability.
• 2.5-inch Vertex Coilovers with 8-stage adjustable damping — customize ride firmness and control to match your terrain, load, and driving style.
• Monotube shocks with external reservoir — optimized heat dissipation and consistent performance under heavy use.
• Radius arm drop brackets — maintain near-stock steering geometry while your ride height increases, reducing alignment drift and component wear.
• All necessary hardware and adapters — a complete, install-ready package so you can upgrade with fewer trips to the parts store.

Installation at a glance

The upgrade is a substantial install that requires cutting and drilling to complete. Plan for an estimated 6–10 hours for a home installation, depending on your experience and tools. A dedicated workshop space, a basic set of hand tools, and follow-along notes or a current install guide will help you finish efficiently while achieving solid alignment and ride characteristics.

Who benefits most

• Off-road enthusiasts who want serious ground clearance without sacrificing ride quality on daily drives.
• Truck owners planning to run larger tires (up to 35 inches) for improved traction and approach/departure angles.
• Tow and haul users who need stable, composed handling under heavy loads and uneven terrain.
• DIY installers seeking a comprehensive, high-performance coilover system built for the Ford Super Duty platform.

Performance and long-term value

Beyond the initial transform, this lift kit is backed by Rough Country’s Limited Lifetime Replacement Warranty, protecting against manufacturing defects and providing peace of mind as you spend years enjoying enhanced capability. The combination of Vertex Coilovers, preserved suspension geometry, and robust construction translates to a more confident ride, better control in rugged environments, and a custom look that stands apart on the road and trail.
