Timbren has engineered hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down at 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, Timbren’s hollow rubber springs adjust robotically to keep the vehicle level always. This SES Suspension Upgrade replaces the jounce stop at the frame. Its unique design ensures superb ride quality – loaded or unloaded. (There must be a 1/2″ to 1 1/2″ gap between rubber spring and axle to verify unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the most efficient of both worlds.DR1500DQ replaces the bumpstops at the rear suspension of the 2009-2022 RAM 1500 2WD and 4WD pickup truck models with crew cab and quad cab. This kit is rated at 8600 lbs capacity. Despite the fact that you’re increasing the spring rate by adding this upgrade, this doesn’t increase the GVWR (Gross Vehicle Weight Rating). Please ensure that the load does not exceed the GVWR set by the manufacturer.
