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

Upgrade your Ford F-250/F-350 Super Duty (2017–2022) with Rough Country’s 4.5-inch Coilover Suspension Lift Kit and discover a new standard of capability and control. This all-inclusive package adds serious ground clearance, enabling up to 35-inch tires, while preserving the smooth, factory-like ride you expect from a modern Super Duty. Built to handle real-world tasks—from daily highway cruising to off-road adventures—the kit is engineered to keep your geometry as close to stock as possible, even with substantial lift.

Why this kit stands apart

What sets this 4.5-inch lift apart is Rough Country’s focus on maintaining precise suspension geometry. Instead of a generic reconfiguration, the kit employs ultra-durable radius arm drop brackets that bolt directly into factory mounts, preserving angles and ensuring predictable handling. The centerpiece is the Vertex Coilover system—a 2.5-inch piston, nitrogen-charged, 8-stage adjustable coilover with a monotube design and external reservoir. This configuration delivers heightened damping sensitivity and a larger oil capacity, resulting in a more controlled ride over rough terrain while maintaining comfort on pavement. With a remarkable 56% greater fluid capacity than the average reservoir shock, you’ll notice steadier body control and improved heat dissipation during demanding use. A dedicated monotube shock is paired with each kit to optimize damping across conditions.

Installation and practical notes

Prepare for a hands-on project with an estimated 6–10 hours for installation. The process does involve cutting and drilling to accommodate the new geometry, so a careful, measured approach is essential. After installation, a professional alignment is highly recommended to maximize tire contact, steering response, and overall ride quality. While this is a DIY-friendly upgrade for experienced hobbyists, the results are best enjoyed with precise setup and proper tuning.
