Driver Front Damping Engineered for GM HD Duty Cycles
The ICON 76551RD is the driver side front VS 2.0 HD piggyback reservoir shock built for 2011-2026 GM 2500HD and 3500HD trucks running 0 to 3.5 inches of front lift. As the companion to the passenger side 76551RP, this shock carries its own remote piggyback reservoir to add oil volume and fight fade during hard braking, plow use, or heavy front axle loading. The internal valve stack is tuned specifically for GM HD front geometry, delivering controlled, predictable damping instead of a generic aftermarket curve.
Key Features
