Enhance the front suspension of your 2011-2023 GM Duramax 2500HD/3500HD 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 front end sag.
