Recommended Suspension Upgrade For A 2021 Newmar Bay Star 3626 Class A Motorhome That Leans

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?

@Terry SumoSprings offer load-leveling support with a progressive resistance for a smoother ride. Essentially you have a soft spring that gets stiffer as it compresses and tries to force the weight back up so it can expand back to its original shape. This means that every time your motorhome leans to one side the spring will try to force it back up so the motorhome isn't leaning. The capacity of the spring versus the weight coming down on it is a major factor here so too low rated of a spring obviously wouldn't give you the results your looking for. That being said you also don't want to go too high in capacity because then the spring won't want to compress and you'll get a bumpy ride. I put some Sumo's on my truck while the shocks and coil springs were pretty much toast just to see what kind of improvement it would make prior to me replacing them and the first thing I noticed just driving around the parking lot was that my truck no longer leaned wildly to the side when making turns. I kind of forgot what it felt like not sliding around in my seat at that point so it was a major improvement in my book. I think I went a little too heavy though because while unloaded my ride quality is a bit bumpier. Adding SumoSprings isn't going to fix the problem 100% but it can definitely make the experience better. We'll just want to make sure we're picking out the right capacity for your specific model. Can you tell me which Newmar model you have and I can start looking into fits?
