Product Details

The ICON Vehicle Dynamics 77738P are Vehicle Specific (V.S.) 2.5 Series piggyback front shocks designed for GM HD trucks lifted 6–8 inches. Each shock is engineered and tuned specifically for this application — matching the correct travel length and damping calibration for optimal performance both on and off the road.

At the core of ICON's V.S. 2.5 Series design is a 6061 billet aluminum manifold positioned just below the top cap. This manifold creates an internal Bump Zone — a proprietary feature that delivers an additional 20% increase in damping force during high-velocity compression events. The result is improved resistance to harsh bottom-outs and superior suspension control when the terrain demands it most.

Key Features:

  • Vehicle Specific (V.S.) length and damping tune for GM HD 6–8" lift applications
  • 2.5 Series piggyback reservoir design for increased fluid capacity and heat dissipation
  • Extended travel construction for lifted suspension fitment
  • Internal Bump Zone via 6061 billet aluminum manifold — adds 20% damping force at compression
  • Prevents harsh bottom-outs and controls high-velocity suspension movement
  • 100% rebuildable and 100% revalveable for long-term serviceability
  • Sold as a pair (2 shocks)

ICON Vehicle Dynamics V.S. 2.5 Series shocks are built for enthusiasts who demand professional-grade suspension performance on and off the trail. The rebuildable and revalveable construction ensures these shocks can be maintained and recalibrated over the life of the vehicle, making them a long-term investment in ride quality and capability.
