This SES Suspension Upgrade fits the rear suspension of a 2021 to 2022 Ford F-150 Raptor 4x4 pickup truck. Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. We have engineered our 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 are pulling a trailer or carrying a heavy load in the bed of your truck, our hollow rubber springs adjust automatically to keep the vehicle level at all times. This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality-loaded or unloaded. Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds. This kit is rated at 3,000 Pound capacity. Even though you are increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
