Rough Country's Vertex 2.5 Reservoir Rear Coilovers bring monotube damping technology and remote reservoir performance to the 2021-2026 Bronco, purpose-built for rigs running a 3.5-inch lift. Nitrogen-charged internals, a massive 2.5-inch piston, and a steel-braided remote reservoir line combine to deliver fade-resistant damping through repeated hard hits on the trail. Application-specific valving balances off-road capability with daily-drive comfort, so the Bronco stays composed whether the terrain is rock-crawling technical or highway miles home.
Monotube construction with remote reservoir cooling. The monotube design separates oil and nitrogen gas for consistent, cavitation-free damping. The external remote reservoir increases total oil volume, giving heat generated during sustained off-road use more fluid mass to dissipate through. The result is a coilover that resists fade run after run, rather than fading progressively as temperatures climb.
Heavy-duty internals built for punishment. An 18mm chrome-hardened piston rod resists bending and corrosion under lateral stress, while a honed steel body ensures smooth, consistent piston travel throughout the stroke. A 3-stage seal system locks out dirt, trail debris, and moisture to protect those internals from the outside in.
Corrosion protection engineered for long-term exposure. A zinc-plated finish topped with a double clear coat gives these coilovers over 400 hours of salt spray resistance, protecting the hardware on vehicles that see mud, saltwater crossings, or winter roads. CNC-machined billet aluminum accents and a laser-etched bracket system complete a finish that holds up as well as it looks.
