Roadmaster or Hellwig

We chose the Roadmaster over the Hellwig for our Ram 3500 SRW because it mounted to the axle housing in a more outboard, OEM fashion, at the bottom of the shock mounts. The Hellwig mounts more inboard with a clamp around the axle making it less effective IMO. We also installed lower Stable Loads (stainless steel versions). They offered some improvement in sag, handling, and even reduced sway slightly (at highway speeds)—-nothing dramatic. They work especially well when used in conjunction with slightly pressurized airbags.
