While the factory rear bump stops do a satisfactory job of absorbing impacts on a street driven truck, ICON found that there was much room for improvement during spirited driving in rough, off-road terrain. The ICON Vehicle Dynamics 2021-2023 Ram 1500 TRX Rear Hydraulic Bump Stop System was designed to take the off-road capability of the truck to new levels by significantly improving the bottom-out control of the rear suspension and reducing rear end kick. Like all ICON hydraulic bumps stops, these feature both velocity and position sensitive technology which means that as the shaft speed increases and moves through the travel, the damping force increases exponentially to provide excellent bottoming resistance that won’t negatively affect articulation. This system features 2.5” diameter, one-piece impact extruded and hard anodized aluminum bump stop bodies with an internal reservoir design for improved damping and more consistent, predicable performance than 2.0” diameter, emulsion style bump stops. To compliment the larger body diameter, these bump stops also incorporate heavy duty 1.625” diameter hardened chrome plated shafts.
