This kit is paired with Cognito 2.0 Remote Reservoir Aluminum shocks, engineered specifically for GM HD trucks to deliver exceptional ride quality, control, and durability in a direct bolt-on package. The external reservoirs increase oil capacity and improve heat dissipation to help maintain consistent damping performance under demanding conditions while adding a clean, aggressive appearance. Eliminates oil aeration allowing maximum performance from the factory-tuned, precision valving. They're easy to install and provide a comfortable on-road ride and predictable off-road handling in even the toughest conditions. The result is a complete suspension system designed to enhance the appearance, capability, and performance of your truck while maintaining everyday comfort and drivability.
