GMC Sierra 3500 HD Shock Kit - Rear - ICON - VS 3.0 Remote Reservoir w/ CDEV - ’11–’26. A purpose-built rear shock package that adds control and consistency for work, tow, and trail.

The 3.0 in. body ups oil volume and piston area for consistent damping. A nitrogen-charged monotube and remote reservoir manage heat to cut fade. ICON’s internal Bump Zone adds up to 20% more compression near bottom-out. CDEV enables in-cab compression adjustment when paired with ICON Intelligent Control (IIC). Vehicle-specific valving, premium 5WT oil, a one-piece linear compression/digressive rebound piston, and a 7/8 in. induction-hardened shaft target durability and traction.
