Recommended Suspension Upgrade For A 2021 Newmar Bay Star 3626 Class A Motorhome That Leans
Products Featured in This Question
Question:
I have a 2021 Newmar Baystar 3626 Class A that leans to the passenger side in the rear when just sitting still. Im looking to upgrade the suspension to hopefully take away the lean and have been looking at the SUMOsprings. Is this the best product or should I b looking at something else? Thanks,

Expert Reply:
Typically if your motorhome is leaning one way it just means either the manufacturer or you have it too much loaded on one side, but this could also be an indication that there's an issue with your suspension so I highly recommend everything is is in good shape and that nothing is damaged before adding on anything.
Once you know your suspension is in good working order then yes, I definitely recommend installing some SumoSprings. These will give you a much smoother ride over the Timbren's and work independently to help level out your lean. We install these on motorhomes every week and they are definitely worth every penny.
For the front of your 2021 Newmar Baystar 3626 Class A Motorhome you'll need the SumoSprings Rebel Custom Helper Springs # SSF-173-40-2 and for the rear you'll need the SumoSprings Maxim Custom Helper Springs # SSR-183-54-1.
I've attached installation videos for both below to help walk you through the installation process if you choose to complete it yourself.

Kevin, I spoke with the manufacturer because I have a 2023 Newmar that is leaning on the passenger side as well They told me that adding Sumo Springs would NOT solve the leaning issue but, would make the ride smoother???? So what's the real story / truth?
