Description

Experience enhanced off-road control and a customizable ride with the Rough Country Vertex 2.5 Adjustable Reservoir Coilovers. Engineered for the 2019-2024 Chevrolet Silverado 1500 and GMC Sierra 1500 4WD models, these coilovers are designed to deliver superior performance on any terrain. The core of the Vertex system is its 8-stage adjustable damping, allowing you to fine-tune the suspension for optimal comfort or aggressive off-road performance with a simple dial adjustment. The monotube design, filled with nitrogen and featuring an external remote reservoir with a durable steel-braided line, ensures consistent damping, increased oil capacity, and superior heat dissipation, preventing fade even under extreme use. Construction includes a massive 2.5-inch piston and a 22mm chrome-hardened piston rod for maximum durability in harsh conditions. Durability is further enhanced by a 3-stage seal system to prevent leaks and contaminants, a honed steel body, and heat-treated alloy bearings for extended longevity. The coilovers boast a premium zinc-plated finish with a double clear coat, offering over 400 hours of salt spray resistance for exceptional corrosion protection. Aesthetic appeal is provided by CNC-machined billet aluminum accents and laser-etched branding. It is important to note that these coilovers are designed exclusively for vehicles already equipped with a lift for optimal fitment and performance. Due to variances in motor weight, they do NOT fit diesel models. Furthermore, they are not compatible for installation with a strut spacer, as this could compromise proper fit and functionality. An adjustment wrench is sold separately.
