We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs (weight from a snowplow or heavy aftermarket accessories – such as a steel bumper) the harder they work to prevent front-end sag.
FF350SDC* replaces the bumpstops on the front suspension of the 2005-2021 Ford F-350 2WD and 4WD pickup truck and cab and chassis models. *For a complete listing please refer to the FITMENT tab below.
This kit is rated at 3000 lbs capacity. Even though you’re 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.
