ICON's 2014-UP RAM 2500 4WD 2.5” Stage 2 Suspension System is made up of dual rate front coil springs, necessary bracketry and hardware, as well as 2.5 Aluminum Series reservoir front and rear shocks. This system improves ride quality and performance both on and off road. The ICON stage 2 system is great for towing, rough construction site terrains, and country dirt roads all while keeping a smooth highway feel. ICON 2.5 Aluminum Series 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. With the endless hours ICON has spent testing and tuning our suspension components and shocks as a complete package, you can rest assured you have the best suspension solution on the market.
