Product Details

The ICON Vehicle Dynamics 78725 is a complete suspension upgrade system for 2011-2019 GM 2500HD/3500HD trucks with 0-2" of lift. This integrated system combines tubular upper control arms with 2.5" Vehicle Specific (V.S.) shocks featuring remote reservoirs and ICON's proprietary CDC Valve (Compression Damping Control Valve) technology for adjustable performance.

Delta Joint Technology:

The tubular upper control arms feature ICON's patented Delta Joint, a revolutionary high-angle ball joint that combines the durability of a traditional ball joint with the performance characteristics of a uniball. The Delta Joint features a zinc-plated corrosion-resistant housing with an integrated grease seal to protect against the elements. The greaseable, metal-on-metal design ensures long service life and noise-free operation while providing greater angularity than standard ball joints and superior weather resistance compared to traditional uniballs.

Upper Control Arm Construction:

  • CNC-bent 1026 DOM steel tubing for maximum strength
  • Semi-gloss black powder coat finish for corrosion resistance
  • Built-in caster correction for optimal alignment and handling
  • Nearly 50% increased wheel travel when paired with ICON shocks

2.5 Series VS Shock Features:

  • Vehicle-specific valving and length configuration optimized for GM 2500HD/3500HD applications
  • Remote reservoir design improves heat dissipation and reduces shock fade during extended use
  • CDC Valve provides 10 levels of externally adjustable compression damping force
  • 6061 billet aluminum manifold creates internal Bump Zone with 20% additional damping force to prevent harsh bottom-outs
  • One-piece digressive piston design for superior on-road and off-road performance
  • 7/8" diameter induction-hardened, chrome-plated shock shaft
  • Premium grade 5WT shock oil for consistent damping across wide temperature ranges
  • 100% rebuildable and 100% revalveable construction

This complete system delivers outstanding off-road capability while maintaining smooth on-road ride quality. ICON now requires GM 2500HD/3500HD upper control arms to be purchased as a complete system with matched shock absorbers to ensure proper compatibility and performance.

Application: 2011-2019 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with 0-2" lift
