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

These ICON 2.5 Series shocks are built 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. They're designed to give your truck a better ride on the street and more control when you're off-road. ICON tunes these shocks specifically for each application, meaning they're set up to work with your truck's weight and suspension geometry right out of the box.

What sets these apart is the combination of features for improved damping. The one-piece digressive piston works with vehicle-specific valving to offer a smooth ride and solid control. When the suspension compresses hard, ICON's internal "Bump Zone" kicks in, adding about 20% more damping force to prevent harsh bottom-outs. Plus, the external CDC Valve lets you dial in 10 levels of compression damping with a simple knob turn, so you can adjust the ride for different loads or terrain.

The shocks themselves are constructed with one-piece, impact-extruded aluminum cylinders that resist corrosion and maintain a consistent finish. They use premium 5WT shock oil for reliable damping across various temperatures, and the remote reservoir design helps dissipate heat, reducing shock fade during long runs or heavy use. All the CNC-machined components are made from 6061 aircraft-grade aluminum, and the 7/8-inch induction-hardened, chrome-plated shaft is built to last. These shocks are fully rebuildable and revalveable, meaning you can service them for years of dependable performance.
