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

Take your Ford F-250/F-350 Super Duty 4WD (2017-2022) to new heights with Rough Country’s 4.5-inch Coilover Suspension Lift Kit, built around Vertex Coilovers for a performance upgrade that doesn’t betray your daily drive. This all-inclusive kit is designed to transform stance and capability while preserving the smooth ride you expect from a factory setup.

Why this lift stands out

• Vertex Coilovers with a 2.5-inch piston: nitrogen-charged, eight-stage adjustable, and monotube with an external reservoir. This design delivers precise damping, quick response, and substantial oil capacity to keep performance consistent under demanding conditions.
• Greater fluid capacity: Rough Country’s 2.5-inch piston design provides ≈56% more fluid capacity than the average reservoir shock, improving cooling, damping stability, and fade resistance on rough trails or long highway pulls.
• Factory-like geometry: Ultra-durable radius arm drop brackets bolt into factory mounts, preserving proper angles and steering feel. By maintaining geometry close to stock, you keep predictable handling and reduce wear on components.
• Broad tire compatibility: Enables running up to 35-inch tires, unlocking a commanding presence and enhanced off-road traction without compromising daily usability.
• All-in-one kit: Everything needed for a total transformation is included, streamlining the upgrade from lift to ride quality in one package.

Performance and ride quality

Replacing the factory independent coil/shock setup with a robust Vertex coilover system gives you the best of both worlds: a dramatic lift and a controlled, comfortable ride. The monotube design with an external reservoir optimizes damping sensitivity, so you experience consistent traction and confident handling on washboard roads, gravel trails, and paved highways alike. The geometry-conscious bracket design helps you maintain factory-like steering response and reduces the likelihood of binding or accelerated wear during articulation.

What you get and how it helps you

• Impressive lift height for a commanding road presence and increased off-road clearance.
• Compatibility and installation designed to bolt into place with proper alignment, though installation requires cutting and drilling, with an estimated 6–10 hours to complete—so you can tackle it as a weekend project or have a shop handle it for you.
• Durability you can feel from the high-grade components and reinforced brackets to sustain aggressive off-road use and daily driving alike.

Who this kit is ideal for

Ideal for serious off-road enthusiasts who want a dramatic lift without sacrificing ride quality on everyday roads. It’s a fit for Ford F-250/F-350 Super Duty owners focused on big tires, enhanced ground clearance, and controlled, predictable handling across varied terrains. If you’re upgrading from stock or a smaller lift, this kit delivers a noticeable upgrade in capability and presence.
