Need a rear shock setup that actually keeps up with how you use your truck? The ICON 2.5 Rear Shock System with CDCV is designed to eliminate the instability, bounce, and fade you get from factory shocks, especially when towing, hauling, or driving rough roads. Stock rear damping just can’t manage heat or weight effectively, which leads to a loose, unsettled feel. This setup fixes that by delivering consistent control and a planted, predictable rear end in every condition.

What really makes this system stand out is its ability to adapt. With externally adjustable CDCV compression tuning, you can dial in ride quality based on how the truck is being used. Run it softer for daily driving and comfort, or firm it up to control squat and body movement under load. It’s a noticeable difference in both ride quality and confidence, giving you a truck that feels controlled instead of reactive.

Built around ICON’s V.S. 2.5 aluminum shock platform, this system uses a monotube design paired with a piggyback reservoir to increase oil volume and improve heat dissipation. That added capacity helps prevent fade during long drives, towing, or repeated impacts, keeping damping performance consistent when it matters most.

Internally, the shock features ICON’s precision valving along with an integrated “bump zone” that increases damping force near full compression to help control bottom-outs and maintain stability under aggressive use. The aluminum construction, hardened chrome shaft, and fully rebuildable design ensure long-term durability and serviceability. Combined with multi-level CDCV adjustment, this is a rear shock system built for real-world use, towing, off-roading, and everything in between.
