4.5 Inch Lift Kit | C/O V2 | Ford F-250/F-350 Super Duty 4WD (2017-2022)

Take your 2017–2022 Ford F-250/F-350 Super Duty 4WD to new heights with Rough Country’s 4.5-inch Coilover Suspension Lift Kit (C/O V2). This all-inclusive upgrade is engineered to deliver taller stance, improved off-road capability, and a remarkably smooth ride that stays true to factory manners on everyday roads.

What sets this kit apart

• Vertex Coilover upgrade replaces the factory independent coil setup with a robust 2.5-inch piston, nitrogen-charged, 8-stage adjustable Vertex Coilover. Its monotube design with an external reservoir increases oil capacity and damping sensitivity for consistent performance from the trail to the highway.
• Geometry-preserving design features ultra-durable radius arm drop brackets that bolt directly into factory mounts, maintaining proper alignment and steering feel while delivering the lifted stance you want.
• Impressive fluid capacity Rough Country’s 2.5-inch piston design delivers ~56% greater fluid capacity than the typical reservoir shock, ensuring cooler operation and more predictable damping under demanding conditions.
• All-in-one convenience kit includes precision-fit components and hardware needed for the transformation, so you’re not hunting down parts piecemeal.
• Up to 35-inch tire potential capability lets you run larger tires while preserving a smooth, factory-like ride—if you choose, you can push the look and capability further without compromising daily drivability.

Why it matters for real-world use

The 4.5-inch lift isn’t just about height—it’s about how the truck handles tougher tasks. The Vertex Coilover system maintains control and comfort when you’re crawling over boulders, crossing washouts, or towing heavy loads. The external reservoir on the monotube design helps dissipate heat during long, technical climbs, so damping remains steady even after hours of use. And because the geometry is retained, steering feel, cornering predictability, and return-to-center effort stay closer to what you expect from a stock Ford, just with added capability.

Ideal use cases

• Off-road enthusiasts who want the aggressive stance of a larger tire with controlled, confident handling.
• Overlanders and trail runners who demand consistent damping on long days in rough terrain.
• Heavy-duty daily drivers that occasionally tackle worksite roads or challenging job sites without sacrificing ride quality.
• Owners aiming to improve approach/departure angles and overall ground clearance for gear and payload.

Installation notes

The lift kit is designed for a professional-grade upgrade experience. Expect cutting and drilling as part of the installation, with an estimated 6–10 hours to complete the full transformation. The kit’s precision-fit brackets and components are intended to bolt into factory mounts, enabling a straightforward upgrade for capable DIYers or shop installs. While the process is substantial, the end result is a reliable, long-lasting lift that holds its geometry under load and terrain.

Warranty and peace of mind

Rough Country backs this suspension upgrade with a Limited Lifetime Replacement Warranty against manufacturer defects. That means coverage for structural and workmanship issues from the date of purchase, giving you confidence to push the limits of your Ford F-Series with less worry.

Upgrade your Ford F-250/F-350 Super Duty 4WD with the 4.5-inch Coilover Suspension Lift Kit (C/O V2) and experience a purposeful blend of rugged off-road capability, controlled on-road behavior, and a towering, assertive presence. This isn’t just a lift—it’s a thoughtfully engineered system designed to preserve ride quality while unlocking new heights and tire options.
