Likely the best upgrade we’ve made to our RV. Easy install, with great benefit. No more rocking when going over uneven surfaces.

My 2016 Thor gas RV on a Ford F-53 chassis did a lot of swaying and rocking around on uneven roads. Many videos online suggested installing a set of Sumo Springs to reduce the sway. The videos looked easy enough and even gave me the part numbers I would need to order. I ordered them and there were here in 3 days! crawled on my back under my RV to remove original Ford sway bumpers. Discovered I didn't have the tools for the job. Hired a local shop to do it. They got the old bumpers out and informed me I had ordered Sumo Springs too small for my RV. Returned the old ones (easy to do at Amazon) and ordered the correct ones. The correct ones arrived in 2 days!! Installed them per instructions. They do a very good job of reducing the front sway. So good that I ordered rear springs too.

We have a 2020 Georgetown 369xl. Just put these on (after putting over 17K miles on), and wish I did it a long time ago! Wow, so nice. Ride is a little stiffer, BUT the handling is so much better! I can now drive with 1 hand. 2 lane hwy truck wind not even noticeable. 4 lane passing trucks barely noticeable. Cross winds, certainly better. I can now feel comfortable in higher winds, and no longer over steer. Well worth it! Easy to install yourself. I am amazed at how much better it is!

I purchased the front and rear sets for my 2020 Class A Thor Outlaw 38MB. It's 40' long, 13'3" tall, and 26,000 GVW.The install - This was a simple install with the correct tools. I had to call tech for help with the rear install but they were easy to deal with.The ride - OMG! THIS IS HOW IT SHOULD HAVE DRIVEN FROM THE FACTORY!It drives like a work truck now. Got rid of the sway, and rocking. Took out road noise. Best $1000 spent

I've added all kinds of things to our 35' RV to improve the ride. New shocks, tires, anti-sway bars, a steering suppressor among others. There has been no single improvement I've made that had as large an impact as the Sumos! They immediately and significantly reduced body roll and bounce. The difference was especially pronounced when loaded.They were easy to install (front more so than back), not a huge investment and made a difference coming out of the driveway the first time. Defiantly worth the investment.

I am very happy with the performance of the Sumo Springs. It has helped a lot to reduce sway and has made the ride more positive and comfortable.However double check you have ordered the correct springs to suit your chassis. It took several attempts for me to place the order and on the last attempt somehow the order changed from 18000 lb chassis (which is the model I have) to 22000 lb chassis and didn't realise the change when order was placed and accepted.The 2 x chassis have completely different mounting brackets. I had to fabricate new mounting brackets to suit my 18000 lb chassis and all has worked out in the end.

If you are on the fence about purchasing do yourself a favor and buy them. Makes a world of difference in ride. Easy install once you get off the front wheels. Installed on my 2019 Baystar 24k chassis.
