Quick Ship SKU #: TB-GMRCK25D Timbren GMRCK25D SES Rear Suspension Bump Stops 11-23 GM 6.6L Duramax

Enhance the rear suspension of your 2011-2023 GM 6.6L Duramax 2500HD/3500HD 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 rear 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.
