GMC Sierra 1500 Shock Absorber Set - Rear - ICON - 2.5 Series VS PB CDCV, 2019–2021. This vehicle-specific piggyback shock pair delivers confident off-road control with a composed ride on pavement.

Engineered for GM 1500, these nitrogen-charged monotubes use piggyback reservoirs to shed heat and reduce fade. The CDC Valve offers 10 levels of compression tuning, while ICON’s internal Bump Zone adds about 20 percent damping near full compression to help resist bottom-outs. Hard-anodized aluminum bodies, a 7/8 in shaft, PTFE-lined bearings, and premium 5WT oil deliver durability and consistency. 100 percent rebuildable and revalveable. Fits most 2019–2021 Sierra 1500 with 0–2 in rear lift; not recommended with added rear lift on Sierra AT4; not compatible with 2019 Sierra 1500 Limited or Adaptive Ride Control; may require minor rear mount mods.
