ICON 0-1" Lift 2.5 Series Rear Shock With CDXS 01-26 GM 2500HD/3500HD LB7/LLY/LBZ/LMM/LML/L5P

Looking to get the rear of your GM HD truck under control without giving up ride quality? The ICON 2.5 Rear Shock Set is built to replace the weak factory rear damping and give you real control, whether the truck is empty, loaded, or towing. Stock rear shocks tend to fade quickly and can’t keep up with heat, weight, or rough road conditions, which leads to bounce, instability, and a loose-feeling rear end. This setup fixes that by delivering consistent damping and a much more planted, confident feel in all conditions. The real upgrade here is adjustability. With CDCV compression tuning, you can fine-tune how the rear suspension reacts depending on how you use your truck. Softer settings smooth out daily driving and washboard roads, while firmer settings help control squat and body motion when towing or hauling. The result is a rear end that feels controlled instead of unpredictable, no matter the load. Built around ICON’s V.S. 2.5 aluminum shock body, these shocks use a monotube design paired with a piggyback reservoir to increase oil capacity and improve heat dissipation. That added fluid volume helps prevent shock fade during long drives, heavy loads, or repeated suspension cycles, keeping performance consistent when the truck is working hard. Internally, it features ICON’s precision valving with a “bump zone” that increases damping force near full compression to help control bottom-outs and maintain stability under aggressive use. The CDCV adjuster gives multiple compression settings without opening the shock, while the aluminum body, hardened shaft, and rebuildable design ensure long-term durability and serviceability. It’s built for trucks that see real towing, hauling, and off-road use.
