Need more rear-end control and a smoother, more controlled ride out of your GM HD truck? The ICON 2.5 Rear Shock Set is built to replace the weak factory damping and deliver a much more composed, predictable feel in both loaded and unloaded driving conditions. Stock rear shocks on these trucks tend to fade quickly under heat and struggle to keep the rear end settled over rough roads, washboard terrain, or when towing. This setup tightens everything up, giving you better stability, improved traction, and a noticeably more planted ride.
Built around ICON’s V.S. 2.5 aluminum shock platform, it uses a monotube design with a piggyback/remote reservoir system to increase oil capacity and reduce heat buildup under sustained use. This added thermal capacity helps prevent shock fade and keeps damping performance consistent during towing, off-road driving, or long highway runs. The design also includes ICON’s internal “bump zone,” which increases damping force as the shock approaches full compression to help prevent harsh bottom-outs.
Each shock is fully rebuildable and revalveable, making it a long-term performance upgrade rather than a disposable component. Built with 6061 aluminum components, a hardened chrome shaft, and high-quality internal valving tuned specifically for GM applications, this setup is designed for durability, corrosion resistance, and consistent performance in demanding conditions. The result is a rear shock package that improves control, comfort, and confidence across daily driving, towing, and off-road use.
