GMC Sierra HD Suspension Shock Absorber Set - Front - ICON - 2.5 Series VS PB - 11-16. Front piggyback shocks for 2011-2016 Sierra HD with 6-8 in lifts, tuned for confident off-road control and composed street manners.

ICON Vehicle Specific 2.5 Aluminum Series uses a nitrogen-charged monotube and piggyback reservoir for heat control and fade resistance. A 6061 billet manifold forms ICON internal Bump Zone, adding 20% damping near full compression to help curb bottom-outs. Vehicle-specific digressive valving, a 7/8 in induction-hardened chrome shaft, and PTFE-lined bearings deliver durable, repeatable performance. 100% rebuildable/revalveable; CDCV upgrade available.
