Product Details

The ICON Vehicle Dynamics 77727P 2.5 Series Vehicle Specific shocks deliver exceptional off-road performance and smooth on-road handling for 2001-up GM HD trucks with 6-8 inch rear lift applications. This pair of piggyback shocks is engineered with application-specific length and damping tuning to maximize suspension performance for your specific vehicle setup.

Key Features:

  • Vehicle-specific valving and length optimized for GM HD trucks with 6-8 inch rear lift
  • 2.5 inch shock body with piggyback reservoir design for enhanced cooling and performance
  • Integrated Bump Zone technology uses a 6061 billet aluminum manifold to create 20% additional damping force during high-velocity compression
  • Bump Zone helps prevent harsh bottom-outs and controls suspension during aggressive off-road driving
  • 100% rebuildable and 100% revalveable design for long-term serviceability
  • Precision-engineered for balanced performance across street driving and off-road terrain

Built with ICON's commitment to quality and performance, these shocks provide the perfect balance of comfort and control for lifted GM HD applications. The piggyback design allows for increased oil capacity and thermal management, ensuring consistent performance even during extended off-road use. For applications requiring more adjustability, ICON offers Compression Damping Control Valve (CDCV) equipped shocks and Omega Series bypass options.
