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.

Expert Reply:

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.
