Description

The Rough Country Vertex 2.5 Adjustable Reservoir Shocks are engineered to deliver exceptional off-road performance and a comfortable ride. These shocks feature an 8-stage adjustable damping system, allowing users to precisely tune their suspension for optimal performance on city streets or rugged trails. The monotube design, filled with nitrogen and equipped with an external reservoir, ensures increased oil capacity and enhanced damping sensitivity. Each shock boasts a robust construction, including a substantial 2.5-inch diameter piston and a 22mm chrome-hardened piston rod, designed to outperform standard reservoir shocks. The 2.5-inch piston offers a significant increase in fluid capacity, an impressive 56% greater than average reservoir shocks. A fortified 3-stage seal system guarantees longevity and consistent performance, while the honed steel body provides a durable foundation. For aesthetic appeal, the shocks feature CNC-machined billet aluminum accents, a silver finish, laser-etched logos, and matching decals. These front shocks are specifically tuned for each application and are designed to fit 4WD and 2WD models with 5 to 7.5 inches of lift. The product is compatible with Chevrolet Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD, and Sierra 3500 HD models from 2011 to 2024 (specific year/drive configurations apply). It is important to note that these shocks will ONLY fit with Rough Country NTD style lifts. The installation time is estimated at 2-3 hours. Backed by an industry-leading 3-year manufacturer's warranty, these shocks also feature a remote reservoir with a durable steel braided line and an exceptional >400-hour salt spray rating, ensuring resilience against harsh conditions.
