Behold: The pinnacle of off-road performance and smooth ride quality in an affordable package has arrived with Rough Country’s 2.5 Vertex 8-Stage Adjustable Reservoir Shocks.

These high-performance reservoir shocks offer an elite ride-quality in every situation you face, with an 8-stage adjustable damping system that lets you perfectly dial-in your ride for whatever lies ahead. Whether you want a smooth ride for city streets or the ultimate damping for off-road mayhem, a quick spin of the dial lets you adjust each shock to the exact performance specifications you desire.

Rough Country’s Nitrogen-charged Vertex Shocks feature a monotube design with an external reservoir for increased oil capacity and damping sensitivity. Each shock features a massive 2.5in diameter piston and a high-flow 22mm chrome hardened piston rod that simply dwarfs the competition. When it comes to investing in a high-end shock, you’ll be pleased to find that Rough Country’s 2.5in piston design is beefier and offers an impressive 56% greater fluid capacity than the average reservoir shock.

A 3-stage, fortified seal system ensures your Vertex shocks keep kicking while the beautifully designed honed steel body offers a long lifespan of reliable performance and killer good looks. This shock is designed to be a true eye-catcher, with a beautiful silver finish, laser-etched RC logo, matching "Vertex" decals, and CNC-machined Billet Aluminum accents. Rear shocks feature a durable bracket system with laser-etched logo and a premium braided steel reservoir line.
