Updated 08/07/2018 | Published 08/05/2018



Question:

Hi I have a itasca viva motorhome built on a Ram Promaster 3500 chassis, which would you recommend for the rear. 313-40, 47 or 54?

Expert Reply:

All three SumoSprings kits fit your 2018 Ram Promaster 3500. The difference is the capacity of each. The # SSR-313-54 is the highest rated at 2,800 lbs, the part # SSR-313-47 is 1,500 lbs, and the # SSR-313-40 is 1,000 lbs.

Due to the weight of your motorhome I'd recommend the highest capacity kit # SSR-313-54 which will make the biggest difference.
