Enhance the rear suspension of your Ram 6.7L 4500/5500 Cab & Chassis 2WD/4WD with the Timbren SES (Suspension Enhancement System) to provide improved vehicle handling. This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality – loaded or unloaded.
Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. Timbren engineered their hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag.
