The Hellwig Contact Helper Spring kit for 2016–2021 Ford F-250 pickups with factory contact overload springs adds two extra leaves to boost support under load. The contact helper engages earlier, stiffening the overload springs to reduce sag and improve level-load capacity while maintaining the factory ride when empty. The bolt-on kit is intended to increase payload carrying stability without altering unloaded comfort.
