ICON Vehicle Dynamics suspension systems for the 2014-2018 Ram 2500 4WD were designed with exceptional performance and ride quality in mind. This Stage 1 system includes ICON-engineered 4.5” dual rate coil springs, high-strength laser cut bracketry, billet bump stop spacers, fabricated rear coil spacers, and all hardware necessary for a complete install. Vehicle-specific ICON 2.0 Aluminum Series shocks help deliver balanced performance front to rear, making it the perfect suspension system for any 2014-UP Ram 2500 4WD that's tasked with daily driving, towing, and light off-road use. This suspension system has been designed specifically by ICON engineers to retain the functionality of factory rear air ride components while also allowing for rear ride height adjustability.
