Product Details

The ICON Vehicle Dynamics 77727CP rear shock set delivers exceptional off-road performance and on-road comfort for 2001-Up GM 2500/3500 HD trucks with 6-8" lift kits. These Vehicle Specific (V.S.) 2.5 Aluminum Series shocks feature piggyback reservoir design with ICON's advanced CDC Valve technology, providing 10 levels of high-resolution compression damping adjustment with a simple turn of the knob.

Key Features:

  • One-piece impact extruded 6061 aluminum cylinders for superior corrosion resistance and consistent finish
  • Nitrogen charged monotube design with piggyback reservoir for enhanced cooling and performance
  • Internal "Bump Zone" technology increases damping by 20% near full compression to prevent harsh bottom-outs
  • Premium grade 5WT shock oil maintains consistent damping across wide temperature ranges
  • CDC Valve provides 10 levels of externally adjustable compression damping force
  • 100% rebuildable and revalveable for long-term serviceability
  • Application-specific length and damping tune for optimized performance

Each shock utilizes a billet aluminum manifold positioned below the top cap to create the internal Bump Zone, delivering an additional 20% damping force during high-velocity compression events. This advanced design helps control suspension movement and prevents harsh impacts when navigating extreme terrain. Sold as a pair for rear axle installation.

Specifications:

  • Shock Body: 2.5" diameter aluminum monotube
  • Configuration: Piggyback reservoir with CDCV
  • Warranty: 1 Year
