The Hellwig Contact Helper Spring kit for 2017–2021 Ram 3500 models with factory contact overload springs supplies an additional leaf to increase load-rate support. The helper spring connects with factory contact pads sooner as the vehicle is loaded, reducing sag and improving level-load carrying capacity while preserving the factory ride when unloaded. It mounts directly to existing contact springs for simple installation.
