ICON Vehicle Dynamics suspension systems for the 2014-UP 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. This kit is designed to only work with trucks that came from the factory with rear air ride suspension.
