Recommended Front SumoSprings for a 2026 Thor Vegas on Ford E450 Chassis  

I added Sumo Springs on My 2018 Thor Vegas. WOW, what a difference ride. Went to South Dakota, Wy, Colorado from South Texas. MotorHome handle very well on some rough roads I also added Koni shocks and Steering stabilizer. Will be adding front and rear sway bar soon.

I have a Jayco Greyhawk 29 MVP. I took etrailer’s advice and put both front & rear summo springs on my Class C Motorhome. I wish I had done it sooner The ride has increased along with the handling. I tow a Highlander on an American Tow Dolly. My wife noticed the smoother ride immediately & asked what had I done. This was money well spent. I also replaced the Ford steering stabilizer dampener with the Bilsten dampener to pair up with my shocks , that was a smart replacement as well. I installed everything in about an hour. It took longer getting things set up than it took for the R&R of the summo springs & Bilsten shock. Thanks again to etrailer’s advice & videos.

The SumoSprings do work as advertised. I installed both front and rear on my 32’Forrest River Forrester class C motorhome mounted on a FordE-450. They did help a lot with body sway. However the camper was still somewhat of a white knuckle driving experience. So if you can afford it I strongly reccomend going with new springs that are made to handle the load of your motorhome. The factory springs are not rated for this much weight. Do yourself a big favor and check out Weldtec designs website before spending a bunch of money on spring helpers and just get the proper springs.

We have a 2009 Itasc Navion Motorhome built on a Sprinter 3500 Series chassis. Over the years I have upgraded the front/rear shocks, installed a larger rear sway bar and installed rear Sumo Springs, all of which has been a big improvement over the standard suspension components. Never thought we needed front Sumo Springs as our motorhome doesn't have a bed/storage compartment above the cab. Last summer prior to our third cross country trip I decided to add a set of front Sumo Springs the same ones you are considering. What a big difference they made Overall a much smoother ride with little to no dive when entering driveways that I didn't realize had a steeper angle than I realized. Currently with just over 90,000 miles since new, I wished I would have installed the front Sumo Springs years ago when I instelled the rear Sumo Springs. For the price it's a no brainer. Hope you enjoy your new motorhome!

I did buy front and rear "bump-stops" for my Sprinter van as well as the largest rear anti-sway bar available. I have only installed the sway bar and front stop as the rear stops are extremely rigid and I am afraid of the rig coming down on me if I really try to force it. That being said, these 2 additions alone have made a tremendous amount of positive difference, with sideways wind gusts being hardly noticeable and potholes and ripple road handling markedly improved. Can hardly weight to have the rear stops put in, as well as adding leaf-helper springs. (not a paid endorsement!)
