Rough Country's 4.5-inch coilover conversion lift kit transforms your 2023-2026 4WD diesel F-250 or F-350 Super Duty into a capable off-road machine without surrendering everyday drivability. The bolt-on system clears up to 35-inch tires, corrects factory rake with front-to-rear leveling, and delivers a noticeably smoother ride than a standard block-and-spacer lift. No cutting and no drilling keeps installation straightforward from start to finish.
Vertex coilovers elevate damping performance significantly. Each unit uses a 2.5-inch piston inside a nitrogen-charged monotube body with an external reservoir that carries 56% more fluid than a standard shock. That extra capacity dissipates heat faster during sustained off-road use, keeping damping consistent lap after lap or trail after trail.
A secondary V2 front monotube shock adds a dual-shock front setup. The added damping from two front shocks improves stability on rough terrain and high-speed dirt roads, giving the front axle more control than a single-shock configuration can provide. Rear shock compatibility extends to optional V2 or Vertex units for a full four-corner performance upgrade.
Radius arm drop brackets maintain proper caster geometry. Lifting a solid-axle truck shifts caster angles, which can cause wander and premature tire wear. The included brackets restore factory caster settings so the Super Duty tracks straight and handles predictably after the lift.
Heavy-duty fabricated rear lift blocks outperform cast alternatives. Built from thicker material than typical cast blocks, they resist cracking under load and feature an anti-axle-wrap design that prevents the rear end from squatting and binding under acceleration, preserving ride quality over the long term.
