Enhance the front suspension of your 99-04 Ford Powerstoke F-250/F-350 4WD with the Timbren SES (Suspension Enhancement System) to eliminate vehicle squatting and sagging and 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. Whether you’re pulling a trailer or carrying a heavy load in the bed of your truck, the hollow rubber springs adjust automatically to keep the vehicle level at all times.
