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.. This hydraulic bump stop system was developed as an OEM replacement, making installation a simple and straightforward bolt-on affair. Simply installing on top of the rear coil springs with the included mounting brackets, you have the option to return the vehicle back to its stock form. The factory rubber bump stops have a limited energy absorption capacity and a rapid release of this energy upon rebound – This translates into a harsh ride and poor handling in rough terrain. ICON hydraulic bump stops absorb and release this energy in a much more controlled manner due to the digressive rebound piston valving, resulting in predictable handling and vehicle dynamics.. Internal reservoir design provides more consistent and predictable performance than emulsion bump stops. Vehicle specific bump stop tune provides smooth engagement and excellent ride quality. Velocity/position sensitive technology exponentially increases bottom-out resistance. Semi-gloss black powder coat finish on brackets for corrosion resistance. Heavy duty 1.625" diameter hardened, chrome plated steel shafts. Impact extruded, hard anodized aluminum bump stop bodies. 100% bolt-on installation on top of rear coil springs. 2022-2023 TOYOTA TUNDRA REAR HYDRAULIC BUMP STOP KIT. 21-23 RAM TRX REAR 2.5" BUMP STOP KIT 2.25" TRAVEL. 2.5” diameter bump stops with 2.25” of travel.
