Hey Dave, the correct Hellwig helper springs you need for your 2017 Mercedes 3500 two wheel drive dually would be the part # HE47QR that you referenced. I'm not sure I've heard the crock pot saying that you mentioned but I think I am going to start saying it now too.

I installed the Hellwig Booster springs on my2024 Winnebago Vita on the 2022 Mercedes Sprinter chassis. I love this upgrade as you can tighten the springs differently side to side to even the load out. In my case the drivers side has a full length slide which makes that side heavier and before this upgrade was always lower. Now everything is level, ride is improved. I would also recommend Fox2.5 heavy shocks for the rear and 1000 lb Sumo springs for the front. 90% of the sway is gone, a pleasure to drive. Travel Safely!
