Which Roadmaster Comfort Ride Suspension Kit for 2019 Grand Design Momentum 351M  

Updated 11/15/2021 | Published 11/14/2021

Question:

I am looking for a suspension upgrade for my 2019 Grand Design Momentum 351M Toy Hauler with 7K# axles. I am laid up right now and can not go look. Would you happen to know which kit is the best option for me? I run the unit pretty close, if not somewhat over its GVWR and it rides pretty rough on the stock system. If this isnt a good upgrade, can you also recommend one? Thank you,

Since your 2019 Grand Design Momentum 351M Toy Hauler has 7k axles which are 3 inches in diameter you'd have to stick with the Roadmaster Comfort Ride # RM-2460-2570 that was designed for the axle capacity and size you have. Going to the 8k capacity wouldn't work as that axle diameter is 3-1/2 inch.
