Product Details

ICON Vehicle Specific (V.S.) 2.5 Series rear shocks are engineered to deliver exceptional off-road performance and comfortable on-road ride quality for 2019-2023 GM 1500 trucks with 0-2" lift. These premium piggyback reservoir shocks feature ICON's advanced CDC Valve (Continuously Damping Control) technology and internal Bump Zone design for superior suspension control in all driving conditions.

Key Features:

  • 10-Level Adjustable Damping: ICON's CDC Valve technology provides high-resolution compression adjustability with a simple knob turn, allowing you to fine-tune your ride for any terrain
  • Internal Bump Zone: Unique 6061 billet aluminum manifold design increases damping by 20% near full compression to prevent harsh bottom-outs and control high-velocity impacts
  • Piggyback Reservoir Design: Remote reservoir configuration improves heat dissipation and reduces shock fade during extended off-road use or towing
  • Nitrogen-Charged Monotube: Advanced monotube construction with nitrogen charging ensures consistent performance and fade-free operation
  • Vehicle-Specific Valving: One-piece digressive piston with application-specific valving tuned specifically for GM 1500 trucks
  • 100% Rebuildable and Revalveable: Serviceable design ensures long-term performance and value

These shocks are precision-configured for 2019-2023 GM 1500 applications with 0-2" of lift, providing optimal length and damping characteristics. The CDC Valve externally adjustable compression system restricts oil flow into the reservoir, creating 10 distinct compression damping force ranges to match your driving style and load conditions. Sold as a pair for rear axle installation.

  • Application: 2019-2023 GM 1500 (0-2" Lift)
  • Position: Rear
  • Shock Type: 2.5" Monotube with Piggyback Reservoir
