ICON 2.5 Series Piggyback CDCV Rear Shocks

Take your 2007-2018 GM 1500 suspension to the next level with ICON's 2.5 Series Piggyback shocks featuring Compression Damping Control Valve (CDCV) technology. These shocks are engineered to provide a plush ride on the street while offering the damping force required for aggressive off-road terrain.

Advanced Damping Technology

  • Piggyback Reservoir: Increases oil capacity and cooling efficiency to prevent overheating during high-speed off-road use.
  • Internal Bump Zone: A 6061 billet aluminum manifold provides an additional 20% of damping force in the final stages of compression to prevent harsh bottom-outs.
  • CDCV Adjustment: Externally adjustable valve allows you to fine-tune your compression damping to match your specific driving style or load.
  • Serviceability: 100% rebuildable and re-valveable design ensures these shocks will last for the life of your vehicle.

Whether you are towing, hauling, or hitting the desert trails, the ICON 2.5 Series shocks offer the versatility and performance needed to handle any situation. The combination of the piggyback reservoir and adjustable CDCV makes this one of the most capable rear shock upgrades available for your GM 1500 at GGCRACING.
