1,500-lb Capacity. Upgrade your Winnebago Sightseer Motorhome's front suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
A heavy front load can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your rear axle, your rear tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your Monaco Monarch Motorhome's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.
The springs can also compress by as much as 80 percent to support a heavy front load and to help your factory suspension bear up under the load. This evens out the weight, which levels your Monaco Monarch Motorhome and ensures that your rear tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.
The springs work independently from one another to support each side of your Monaco Monarch Motorhome. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.
These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).
SumoSprings compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.
The helper springs are custom designed to fit your Monaco Monarch Motorhome, and they install easily - no drilling required.

they work as they should . handles much better when towing my trailer.
Easy installation and definitely helped with front sway to some degree. Excellent product and support from E-Trailer.
Purchasing SUMOSPRINGS from etrailer.com made it easy,
Kennika C. ensured that the product was the right one for my RV. Installation was easy took me and my wife (my hands would not fit to reach the bolt) an hour to install, took the RV for a test ride and I notice the difference right away, limiting sway, and the harshness of road bumps. If your having issues with hard road bumps shaking your RV, why wait purchase SUMOSPRINGS.

I had severe vibration on my Right side front tire of RV, now with the new sumosprings I dont have that issue any longer easy to install and they continue to meet my satisfaction. Buy them!
2007 Workhorse W22 chassis, easy install, slight KJ knuckle busting on drivers side, but patience works.

Most Excellent, great ride
Competitive price. Quick shipping
Finished installing somo springs and rear antiswaybar couple of days ago. Products seem to be of excellent quality and installation was relatively easy. Have not been able to get out on the road due to Covid-19 but hopefully will be able to travel in a couple of weeks.
Made a big difference, would recommend this product. Much more stable ride. Was so satisfied with the front, did the back too and it really helped. Do both ends, you won't regret it.
Adding the SumoSprings to the front of my W24 motorhome improved the ride over some of the worst roads I have seen in PA. and NY.

The Sumo Springs on my W-24 chassis have given me a much softer ride during the last 10,000 miles. When you are sitting right over the front axle in a motorhome, you feel every bump in the road. Sumo Springs help smooth out those bumps.
While is was a bit of a struggle to get to the bolt location, I am glad I installed these SumoSprings Solo Custom Helper Springs - Front Axle. Overall, these help to make the RV ride quite a bit more stable and bounce less. The more stable ride allows to drive around corners a bit faster and with less sway.
I installed a pair of these on my Newmar Kountry Star a year ago and I am really impressed with the improvement they made. After installation my motorhome is barely affected when I am passed by tractor trailers. Before the installation of the SumoSprings I was always fighting the wheel when I was being passed by large trucks.
Ordering is always simple at etrailer.com with a very helpful product fit guide. Received product in about a week which fit my plans well. I installed the Sumo front springs and just finished a 200 mile trip from Southern CA to Central CA over our well funded and maintained highways....NOT! We have made this trip more than 20 times and this time we really noticed a difference in ride quality. I can’t wait to get the rear springs next.
These were super easy to install. Not sure they are to thank for the improvement while driving, pretty sure that would be the rear Sumo Springs that I added at the same time. But they are most likely what improved controlling the rocking in and out of driveways.
I put these up front on my Class A RV and it reduced the harshness at the bottom of the suspension stroke. I can go a bit faster with confidence on rough roads or over bumps. E trailer earned my business.
Bought these for my previous RV etrailer always ships promptly and they're great people to deal with give them a try you'll be happy you did

They were easy to install made the ride much more comfortable I think youre a great invention especially for such a low price
One year and 8,000 mi since I installed the Sumo's on the front of my 34 ft Coachmen class A motorhome with a W-22 chassis. Still one of the best suspension modifications I have done to my coach. Great improvement on bridge joints and small pot holes.
Got my spring helpers and they really helped a lot. Just took 1/2 a day to install them. Just took a short test drive and everything was much quieter, with fewer rattles and no big bangs when hitting rough road. We are very pleased.
Very happy with this products and what a great difference on my Holiday Rambler 2006 now i have to buy the rear one as well and the shipping was fast as well highly recommend this product and the dealer as well
