Best RVC Vehicle Suspensions

Happy Camper.

The SumoSprings Helper springs have too much clearance between the spring and the axle. Probably because I have helper springs on the rear axle which raises the Sprinter somewhat.

Super easy install. I used my auto-leveling to lift front wheels to make room - you will need to take weight off of the axle to make room to install. Smoothed out the ride and body roll. Installed front and back Sumo's on my 2020 Jayco Redhawk 29 in about an hour.

Together as a set of front and rear sumo springs and the Hellwig anti-swaybar the ride in my Leisure Travel van is like night and day, improvement and handling!

Front and rear Sumo Springs installed. Have not had a chance to hit the highway as yet. Locally a very good ride. Thanks to Joanne K. for all of her help.

These springs made a big difference in the handling of my Newmar Baystar 31' motorhome. Much improved ride compared to the factory suspension.

Installed on my 2020 Jayco Redhawk 29XK. Easy install. Front and back took about an hour. Worth it! Initial feel is the ride is smoother, haven't gotten out on a longer road trip - I will update when I do. Just the fact the Sumos make continuous contact with the axle where the OEM jounce bumper was there only when the suspension bottomed out means it should have a smoother ride

After adjusting the “helpers” Moreride put on before Jayco build which were a challenge to get information to do these were added Soft feel while absorbing dynamic loads Aided the sway bars handling curves very well Have blue set on my PU as overloads - nice

Hello, i installed the Sumo springs on my 2020 M/B 2500 pleasure Way camper van 19.5 foot, if you do not want to go in for the full suspension upgrades for 5 to 6 thousand dollars the Sumo spring is a decent up grade to help with sway, we aren’t off roaders campers but they work nice in unimproved campsite. I have about 4500 miles on my camper since I installed them which took about a hour. It did raise the camper by about 1/4”. I just used a floor jack and big flat screw driver for the back and deep well socket for the front ones. Sorry I didn’t take a video or picture. But so far I would recommend the sumo springs it is better then stock bump blocks. And thanks to etrailer for getting me the right setup for my camper.

I had to loosen the stabilizer bar in order to install the springs. The stabilizer bar is very tight to the springs. I will be able to see after some driving how much stabilzer bar rubs on the springs. The install was on a 2022 Sprinter 2500.

Received the air shocks in a timely manner. Had them installed yesterday and they make the rv ride much better

Package had been torn open, and the box was empty except for bolts. I have cameras and they were not stolen from my house, so they must have come up missing during the delivery process

The system is working great. The only problem I had were the included bolts. They weren't threaded long enough and, therefore, couldn't be used. I had to use the old bolts and nuts to finish the installation.

Wow, what a difference. Installed on a 2005 Allegro Open Road 30 ft motorhome that has a 2004 Ford F53 chassis. It raised the front ride by an inch or two, so it looks less "saggy" up front. Also took the chatter out of a lot of small bumps in the road. MH feels much more stable on the road and has less roll/lean when corning. Install was pretty straight forward. Only have about 40 miles on them to date, but will give them a good test on a 1200 mile trip in a few weeks.

The installed system works great. The installation was WAY harder then the video suggests because of the limited space to work. Maybe a bit misleading

Installation was a snap! Everything fit with the factory parts that I replaced and was able to do all the work myself. I Leisure Travel van now has a much smoother and less mushy ride. Together with the Hellwig anti-sway bar and front sumo springs this upgrade has really changed the way she handles and feels on the road. Thank you, e-trailer For providing such a fine product line For my van.

Wow! Skeptical to say the least. Researched and You Tubed for weeks before I spent the money. Didn’t think something so simple could help so much, but it did! Huge difference in overall ride and handling quality on my Entegra Qwest motorhome with a Mercedes Sprinter chassis. Spend the money. You won’t be disappointed.

Much harder to I stall than the front units. You need a strong jack, jack stands and a powerful drill. Be very careful about the wires and brake lines inside the chassis. Be prepared to remove the rear wheels, which is a challenge on a dually. It can be done at home, but you need to be pretty handy and very careful. It took me about 2 hours per side, being careful as I went. However, combined with the front helpers they work superbly. The vastly reduce body roll and pitch and make the ride much better. They make the camper much easier to steer as well. Consider having them installed professionally if you are not mechanically adept, but they are well worth the purchase price.

I am sure these are very good, the only reason for the low rating is to get attention so no one makes the same mistake like i did. These DONOT FIT on a 2018 Jayco Greyhawk equipped with the JRide suspension. The Heliwig helper springs are in the way. etrailer application guide needs to be updated, the picture attached show the Heliwigs are in the way.

The sumosprings make a noticable improvement in handling of my RV.

As always, I needed a host of devices to set up our new Toad, and etrailer was the perfect choice! Lot of product, in stock, for a decent price, and shipped quickly! HIGHLY recommend

Just finished installing Timbren's in the rear of my Ford E-450 motorhome. The installation was very easy. The hardest part was lifting up the motorhome so the rear tires were off the ground. I always install Timbren's on all my pickup trucks, and have always been extremely happy with them, so when I bought a motorhome, that was one of the first things I did. Because my motorhome came from the manufacturer with helper springs which increased the height or clearance, the Timbren's were not in constant contact, so I purchased and install a 1" spacer (part number A25723-90AH00). Now the Timbren's are in constant contact and will maintain the correct height and not sag under load. I love Timbrens!

I have a 2022 E450 Sunseeker 2850. Timbren are the way to go. Progressive unlike sumo. I emailed the folks at Timbren and they suggested the heavier duty ones. 12,500 lbs I needed a 1” spacer. My buddy gave me his that we ended up not using on his 3/4 dodge short bed. My goal was to have these barely touching when unloaded. On pick ups you want that 1” space however, motorhomes are heavy and I wanted them to work all the time. My goal was correct. The ride is fantastic. It takes 90% of the hard jolts away. I believe these will make everything last in my motorhome longer. Things don’t rattle like a normal suspension. Not a hard install. It took me a hour. Longer to get out the tools than to get it done.

I installed these front Sumos on my 2023 Ford F53 chassis Class A Tiffin for several reasons. The factory bump stops had fallen out so something needed to be installed. I decided to invest in the Sumos to provide suspension support and get all the benefits of Sumos. I installed them, test drove the coach and am pleased with the results. They help cushion the front end and provide anti roll assistance. They work well with the Konis to soften the natural harshness of leaf springs. I’m very pleased with this addition.

A friend and I installed these, if was not difficult to figure out and was a big savings. My wife noticed the difference without knowing it. On a trip to a frequent location she would complain the entire trip after installation on the same trip she did not complain at all. Success!

These work great. Stops body rolling my loaded Promaster van when cornering. 15 minute install.

I wish I installed these earlier on my Ram Promaster converted into a camper van, the improvement in stability, feel and peace of mind. No longer blown around in high wind, better towing for my boat, firmer feel just driving normal. Hard to describe all the benefits but for how reasonable they are priced and ease of installation certainly wish I had these day one when I bought the van. 100% will install these again on future vehicles and would definitely recommend this to any and everyone

They are great. The leveling rams don’t drag when going over church holes or pulling in or out of parking lots. Vehicles still rides good.

They do work well for helping to control body tilt side to side on our Motorhome. About 2 hours to install all four myself.

The kit got here and it was in good shape and everything that was supposed to be there was there. Haven't tried it out yet but I have no doubt that it's going to work perfectly. The staff was very friendly and a very helpful in picking out the right system for my motorhome, I will add more photos when I get the project done plus a video.

The kit works very well, the driver side install took 4/5 hours with all the extra hoses gas lines, vent tube mount in the way. Had to cut a extra bracket which was under the bump stop and went up the side of the frame, wouldn't let the air bag bolt move over far enough to align with the old bump stop hole. Once that was removed everything was great. The driver took just over an hour. Finding a good location for the airlines still haven't they are in the fender area tucked away for now. They work great, now just seeing what is the best psi for my van. Didn't install a compressor maybe in the future I carry a compressor for work anyway so not hard to add air if needed. Thanks would recommend using these. Plus cheaper and easier that buying new springs and replacing them.

Great product and great company to deal with. Highly recommend Etrailer.

2017 Newmar Canyor Star: We installed the front & rear SUMO springs and the side-to-side sway improved a lot. Total installation time was less than 4 hours.

Made the ride much smoother and steady

I've had these Sumo Springs on my 2018 Thor 26HE Class C with standard sway control for over a year and immediately after I installed them I noticed a huge difference, like night and day. I installed them myself, it was easy but took some time because I had to use a floor jack and blocks for the rear, the front went in very easy. A definite must have. I'm not sure I even need to upgrade my sway control like I originally planned.

Great suspension system, I have had them on all four Ford Transits great stability and load balancing and I haven’t had a failure, excellent for towing, the new pair I bought for my T350 HD has 2 spacers to adjust ride hight. I started out with one spacer and it looks normal and rides smoothly with a 3,500 lb. trailer.

Fell off after 1st drive. Load not that heavy maybe 2000 pounds. Had on last truck no problems. FORD Transit 250 seems to not work and fell off. Bolt stayed tight rubber part came off bolt and washer.

Awesome product and even better customer service.

Great fast service as always
