Do Front and Rear SumoSprings Need to be Installed on 2018 Ram ProMaster 2500 Near GVWR

Question

Question:

I will need Sumo springs for my 2018 Promaster 2500 chassis for a Class B RV which I will be loading almost to the max GVWR. Do you have a recommendation there? Not sure if I need both front and back.

Since you are loading your 2018 Ram ProMaster 2500 up to the GVWR I recommend starting off using the SumoSprings Solo Custom Helper Springs # SSR-313-54 for the rear axle. These are the heaviest duty option available which is what you need for your application.

If you had a passenger vehicle then I would say that the rear SumoSprings would be enough but since you have an RV I also recommend installing the Coil SumoSprings Custom Helper Springs # CSS-1195F. These will not only assist your suspension in carrying weight but they will also help to improve the body roll of your ProMaster.

Since you want comfort over additional capacity you'd want the lighter duty #SSR-313-40 since it wouldn't be as harsh.
