Each laser cut piece of steel is precision bent and powder-coated to verify a quality fit. 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, hollow rubber springs adjust mechanically to keep the vehicle level always. This SES Suspension Upgrade replaces the jounce stop at the frame. Its unique design provides 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 productive of both worlds. FR1504E replaces the bumpstops at the rear suspension of the 2015-2021 Ford F-150 2WD and 4WD pickup truck models. This kit is rated at 6000 lbs capacity. Even supposing 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.
