Product Details

ICON Vehicle Dynamics 2.5 Series Vehicle Specific (V.S.) shock absorbers deliver exceptional off-road performance and smooth street driving for GM HD trucks and full-size pickups. These rear shocks are precision-engineered with application-specific length and damping tuning to optimize suspension performance for your specific vehicle platform.

Key Features:

  • Piggyback reservoir design increases fluid capacity and cooling efficiency
  • 6061 billet aluminum manifold creates internal Bump Zone for 20% additional damping force during high-velocity compression
  • Bump Zone technology prevents harsh bottom-outs and improves high-speed control
  • 100% rebuildable and revalveable construction for long-term serviceability
  • Application-specific valving tuned for GM 2500/3500 HD and 1500 platforms
  • Sold as a pair for complete rear axle coverage

These shocks are compatible with 0-1 inch lift on 2001-up GM HD trucks and 4 inch lift on 2007-2018 GM 1500 pickups. The piggyback reservoir configuration provides superior heat dissipation compared to traditional monotube designs, making these shocks ideal for demanding off-road use while maintaining excellent on-road comfort. For users seeking additional tuning flexibility, ICON offers optional Compression Damping Control Valve (CDCV) upgrades or Omega Series bypass shocks.
