Description

The Rough Country Vertex 2.5 adjustable reservoir shocks are engineered to deliver superior off-road performance and exceptional on-road comfort. With an eight-stage adjustable damping system, you can precisely control your vehicle's ride characteristics, from smooth city driving to aggressive off-road excursions, simply by turning a dial. These shocks boast a robust monotube design enhanced by a nitrogen-charged remote reservoir, which significantly increases fluid capacity and improves damping sensitivity, thereby reducing fade during demanding maneuvers. Constructed with a massive 2.5-inch diameter piston and a high-flow 22mm chrome-hardened piston rod, these shocks offer superior performance compared to standard reservoir shocks, providing an impressive 56% greater fluid capacity. A fortified three-stage seal system ensures durability, while the honed steel body and CNC-machined billet aluminum accents contribute to a long lifespan and aggressive aesthetic. The shocks also feature a zinc plate finish with a double clear coat and have undergone over 400 hours of salt spray testing for enhanced corrosion resistance. Installation is estimated to take 2-3 hours and is designed to be straightforward. These shocks are sold in pairs and are specifically tuned for each application to ensure optimal performance. They come with a three-year manufacturer's warranty covering leaks, diminished damping, and breakage. These shocks are designed for 2020-2024 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD models, fitting both 2WD and 4WD variants equipped with 3.5 inches of lift.
