ICON 71707P: Aluminum-Body Front Shocks for Your GM HD
The ICON 71707P pairs two Vehicle Specific (V.S.) 2.5 Aluminum Series remote-reservoir front shocks for 2011-2026 GM 2500/3500 HD trucks running 0-3.5in of lift. Each shock is length- and damping-tuned specifically for this application, with a lightweight aluminum body and remote reservoir featuring a 6061 billet aluminum manifold "Bump Zone" that adds up to 20% more damping force to control the suspension at high-velocity compression. This non-adjustable version delivers ICON's factory-set tune; for a user-adjustable option, see ICON's CDCV, CDXS, or CDEV-equipped shocks.
