Upgrade the ride on your 2011-2026 GM HD with ICON 2.5 Series shocks. Vehicle-specific valving delivers better damping, less body roll, and a more planted feel on any surface. Remote reservoirs keep operating temps low during extended off-road sessions. CDCV lets you adjust compression damping externally for the perfect setup.

Features
  • Compatible with 0-3.5" of front lift over stock
  • Extended travel length requires aftermarket front upper control arms and provides maximum wheel travel
  • ICON’s internal “Bump Zone" increases damping by 20% to provide more control as the shock approaches full compression
  • Nitrogen charged monotube design with remote reservoir
  • Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
  • ICON's CDC Valve technology allows for 10 levels of high-resolution compression adjustability with the turn of a knob
  • Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
  • One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
  • 7/8" diameter induction hardened, chrome plated shock shaft
  • Press in, bonded rubber bushing/bar pin assembly damps road vibration and provides OE factory type fitment
  • 6061 aircraft grade aluminum CNC machined components
  • One-piece, hard anodized, impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish
Important Notes

  • Shocks Are Fully Serviceable. Lift Heights Indicated Are For A Stock Equipped Vehicle.
  • Compatible with 0-3.5" of front lift on most Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD submodels. Compatible with 0-2" of front lift on Chevrolet Silverado 2500 ZR2 and GMC Sierra 2500 AT4X.
Manufacturer Description

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all ICON shock absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON’s unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal “Bump Zone" that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. ICON's exclusive Compression Damping Control Valves are included for precisely dialing in your suspension performance. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle.

The must do service package. This is a "fits multiple" kit so youll have some extras. The kit also includes the lower unit gear oil seals, which is awesome. I always trust quicksilver to be durable and a great value for the money.
