Which Rear SumoSprings Are Best for a 2020 Winnebago E-350 Motorhome?

Question

Question:

Greetings, Ive purchased several of your products and have been very happy with them. We have a 2020 25 ft E350 Super Duty Winnebago Motorhome, model WF325AR. It weighs 12,500 lb. I just purchased Sumo springs for the front of it. I have not installed them yet but I did put on the steering stabilizer and I really like it. My question is, which model of sumo Springs do you recommend for the back of the vehicle? Our goal is comfort, we get a pretty big jolt when we hit bumps. Thank you for your help! Kevin

Hi Kevin,

Thanks for writing in, and for the kind words! Sounds like you are getting things dialed in just right =)

Sorry for the delay on this one. I had to reach out to SuperSprings International because nothing was showing up in our fit guide for your specific setup, and I refuse to give up that easy. They confirmed that you will need the SumoSprings Maxim Custom Helper Springs for the Rear Axle # SSR-106-40-1.

I really like the Maxim for what you are trying to accomplish, especially since comfort is your main goal. The SumoSprings have a progressive design, so they get firmer as they compress. This helps give you the extra support when you need it while also helping absorb some of those bumps and jolts you're currently feeling through the rear of the motorhome.

Once you get the front SumoSprings installed and add the # SSR-106-40-1 to the rear, you should have a much more supported suspension setup all the way around. Of course, no suspension upgrade is going to make those rough roads disappear completely, but this is definitely the direction I would go for your setup.

And I'm glad to hear you're already enjoying the steering stabilizer! It's always nice when you can feel the difference an upgrade makes right away.

So where is the next great adventure once you get things installed?
