The rear Maxim kits (part numbers ending -1) cannot be used on Sprinters with a 2″ lift block (I will add a note to the Application Guide as it does not specify this). A lot of the motor homes are built on Sprinters that have this block. The most popular SumoSprings for coach Sprinters is the SSR-338-47 (works with or without the block). If your coach does not have the 2″ block, you could use the SSR-336-47-1. I would not use the -54 unless it was for commercial use, or you had a lot of extra weight and something in tow. For the front, I would use the -40 blue kit, SSF-106-40. Hope this helps; let me know.
Hi T.J., Sorry, I’m still confused. I also have a Winnebago Navion/View, which (along with most Class C Sprinter RV’s) is generally near maximum GVWR for a Sprinter 3500 Chassis when packed for travel (including any tow hitch weight). That would indicate to me that the yellow SumoSprings would be the most appropriate for Class C Sprinter RVs. Are there other considerations that are factored in other than weight of the vehicle? You mention “commercial use”? Not sure what that means. Is there a downside (other than maybe a firmer ride) to installing the yellow rather than the black? Like, could it increase roll or sway? Thanks for your insights.
