ICON 01-19 GM HD 0-1in Rear / 2007+ GM 1500 4in Rear 2.5 Series Shocks VS PB - Pair

The 6061 aircraft grade aluminum construction of these ICON 2.5 Series shocks means they're built tough and resist corrosion, while also keeping weight down. These shocks are specifically tuned for a range of GM trucks, including the 2001-2022 Silverado/Sierra 2500 HD and 3500 HD, as well as the 2007-2018 Silverado/Sierra 1500 models. They are designed to give your vehicle outstanding performance off-road and a smooth ride on the street, with a damping tune configured specifically for each application.

ICON's unique internal Bump Zone feature adds an extra 20% of damping force as the shock approaches full compression. This helps prevent harsh bottom-outs and provides better control during high-velocity suspension movements. The nitrogen-charged monotube design with a piggyback reservoir improves heat dissipation, reducing shock fade during extended use. Plus, these shocks are 100% rebuildable and revalveable, meaning you can service and tune them for years to come. The one-piece digressive piston design works with vehicle-specific valving to offer excellent performance both on and off the pavement.

Included with these shocks are PTFE lined spherical bearings and application-specific mounting hardware to ensure a proper fit. For those looking to fine-tune their suspension further, these shocks can be upgraded to ICON's Compression Damping Control Valve (CDCV) system. The premium grade 5WT shock oil ensures consistent damping across a wide temperature range, and the impact-extruded aluminum cylinders provide a durable finish.
