Overview:

The 2011-UP GM 2500HD / 3500HD requires significant shock damping to comply with the massive spring rate of the factory torsion bar system. ICON Vehicle Dynamics has developed a range of suspension systems with optimized vehicle specific shock damping. These systems offer excellent on and offroad driveability. While driving the construction site or trails to your favorite dirt bike location, ICON wants you to get there in comfort just like your drive to work. ICON's Stage 3 system is comprised of V.S. 2.5 Series piggyback front & rear shocks, and tubular uniball upper control arms. The ICON vehicle specific tuned 2.5" shocks are the key to attaining optimum ride quality and getting that desired comfort with the 3/4 & 1 ton working capability. Reservoir shocks ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. Additionaly uniball upper control arms add strength and durability, with the ability to use a longer extended length shock offering 25% more droop travel.

Key Features:

• Vehicle specific tuned 2.5" reservoir front and rear shocks for superior shock damping and control

• Improved ride quality over stock with no change in towing capacity

• 100% Bolt-on system - no drilling, cutting, or welding necessary for install

• 6061 Aircraft grade aluminum CNC machined components

• Corrosion resistant plated shock bodies

• Made in the USA
