Vertex 2.5 Reservoir Front Shocks | 3.5" | Chevy/GMC 2500HD (20-26)

Unrivaled Ride Quality and Precision Tuning: Experience the pinnacle of off-road performance and on-road comfort with Rough Country's 2.5 Vertex Reservoir Shocks. Engineered for enthusiasts who demand elite performance without breaking the bank, these premium shocks deliver smooth handling and rugged durability across any terrain. Built to Dominate, Designed to Impress: Each shock features a massive 2.5-inch piston and high-flow 18mm chrome-hardened piston rod, offering unmatched shock control and fade resistance. The monotube design with external remote reservoir ensures superior heat dissipation and consistent performance, while Nitrogen-charged internals boost response and minimize shock fade in aggressive conditions. Durability That Goes the Distance: A 3-stage fortified seal system keeps out contaminants, extending the life of the shock even in the harshest environments. The honed steel body, paired with heat-treated alloy bearings, provides lasting strength, while a zinc-plated finish with double clear coat and over 400-hour salt spray rating ensures unbeatable corrosion resistance. Premium Styling with Rugged Substance: More than just performance, Vertex shocks stand out with CNC-machined billet aluminum accents, a laser-etched RC logo, and matching "Vertex" decals. Steel-braided reservoir lines and laser-cut brackets on the rear shocks elevate both form and function. Confidence Backed by Coverage: Rough Country backs the Vertex Shocks with an industry-leading 3-year manufacturer's warranty, so you can hit the trail or street knowing your suspension is ready for anything.
