Improves suspension, handling and safety. Progressive spring rate. Provides additional support as needed so you always have a smooth, comfortable ride.My order arrived quickly and correct. I appreciate the tracking emailed to me. The helpers went on easily and just like the video. My only modification was to remove the band on the rear spring. (A five minute task) The RV sits about 1 1/2 inches taller. I prefer this to flipping the axle in order to maintain a low center of gravity. In the picture, the springs actually are vertical when the RV is put back on the ground.
Glenn E - 08/04/2022Worked really well, definitely smoothed out the ride. We are finding significantly less chaos with the equipment in the trailer.
The only complaint I would have is trying to use the Sumo Spring for very small enclosed trailers. The STEEL MOUNT was too tall, to meet the relaxed position height, so we cut 1" out of the mount and re-welded together, and repainted. But other than the additional modification it worked great.
I just installed the SumoSprings on a KZ Sportsmen Classic 160QB and it makes a big difference in stability. I also ordered Part number TSS-CTP (contact plate) from SumoSprings since the travel trailer frame is slightly offset and the Sumospring makes only 60% contact. Always great service and useful info from etrailer.
Easy install on my 2012 Wolf Pup Travel Trailer. I am yet to take it out but the squeak from the leaf springs is gone and it feels much more stable walking around inside. I can’t wait to get it in the road! I gained about 1.5 inches of wheel well space to fender as noted by some other reviewers but my camper is near empty so loaded it will be perfect and I don’t mind having a bit more clearance as I have a low trailer to begin with. No spacers we’re needed for my camper. I would say also I have about .75-1 inch preload vs instructions which say recommended range is 1/4-.5 inches… again I felt OK installing and have used sumo springs in the past with good results.
The Sumo springs for our dual axle 25' camper made it more stable esp on windy days and on bad roads. The stuff didn't get thrown from the cabinets.
Installation was easy after taking off the wheels.
Well-manufactured and designed product. I'm 74 and it took me about two hours to install on my travel trailer, but there were no problems and it seemed to fit perfectly and do the job I wanted it to do, which was support the leaf springs. Shipping was fast and free, and the follow-up is clear and honest. Great job, etrailer!!
Great product, using on a single axle camper with a gross of about 4,800. Had an OEM spring snap before so wanted to ensure the new springs had some assistance for future wear prevention. Trailer is more sturdy to tow for sure. Not a world of difference, but definitely noticeable. Mostly on turns and when larger trucks pass, I can feel the camper shift and sway less, a very welcome feeling. Also, feels slightly sturdy when in trailer. Lastly, it sits a hair higher when fully loaded. Overall, a product I am very pleased with. Price seems a little high for the product you receive (material wise). But, it is a low cost investment for the future.
Worked beautifully on homemade trailer with axle/leaf springs from old Rambler station wagon that easily bottomed out. Needed to do a wacky installation with added spacer, so probably invalidated warranty, but still works like a charm.
Great price, great service, and lightning quick shipping that arrived sooner than expected. Thanks etrailer!
I can't say as yet how they will perform as I haven't got them installed. I just received the springs today
These were a great addition to my creaky dual-axle boat trailer. The banging and clanging on bumps is gone, and swaying on bumps/corners is reduced as well. An excellent investment!
My SumoSprings definitely help with trailer sway on windy days. They were not hard for me to install with standard tools.
Got it and installed last week. Works for the trailer and I am happy with result
httpsThank you Etrailer.
Perfect fit for trailer with axle over leaf springs
the mounting bracket should be shorter
Got the wrong product, BUT I called and explained to Jeoff. I didn’t know if I explained it the right or the person didn’t hear me correctly? It really doesn’t matter, I just needed the right part. They are sending me a return label. Then I ordered the correct part. I’ve ordered from eTrailer before and been very happy. I very happy today, all is well
Already installed on my Toy Hauler trailer! Super happy with them! Thank you!
Only one on market
