Compact Internal Reservoir Damping for the Rear of Your GM HD
The ICON 76552 is a rear VS 2.0 HD internal reservoir shock built for 2011-2026 GM 2500HD and 3500HD trucks running 0 to 1.5 inches of rear lift. Unlike the piggyback equipped 76552RP and 76552RD, the 76552 houses its nitrogen charge and oil reservoir inside the main shock body, giving a slightly more compact package that still delivers vehicle specific valving tuned around the GM HD chassis. It is a strong choice for owners who want the ICON V.S. 2.0 damping curve without the extra clearance needs of a remote reservoir hose and canister.
Key Features
- Vehicle specific valving tuned for the GM 2500HD and 3500HD rear suspension
- Internal reservoir design keeps the shock compact with no remote hose or canister
- 6061 aluminum shock body resists corrosion and reduces unsprung weight
- 7/8 inch chrome plated shaft built to handle heavy payload and towing cycles
- 100 percent rebuildable and revalveable for long term serviceability
- Direct bolt-on replacement for factory rear shock mounting points
