Passenger Front Control That Tames Nose Dive Under Braking
The ICON 76551RP is the passenger 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. Front shocks see more heat and cycling than the rear on a work truck, and the piggyback remote reservoir on the 76551RP adds the extra oil volume needed to resist fade during hard braking, plow work, or repeated heavy hauling. The valving is tuned specifically for the front geometry of the GM HD platform rather than adapted from a lighter duty application.
Key Features
- Vehicle specific valving tuned for the GM 2500HD and 3500HD front suspension
- Piggyback remote reservoir increases oil volume and resists fade under hard use
- 6061 aluminum shock body resists corrosion and reduces unsprung weight
- 7/8 inch chrome plated shaft built for heavy front axle loads
- 100 percent rebuildable and revalveable for long term serviceability
- Designed specifically for the passenger side front mounting position
