Very easy to install plan taking big trip in a few months can’t wait to see how they handle. Update to follow.
by: Philip H01/05/2024
Only 4 stars since I have only used them on one RV trip so far. I installed these in conjunction with an equalizer upgrade (Morryde SRE 4000) on my 2019 Grand Design Reflection TT. For the one trip I have been on, I liked how these helped cushion the ride of the trailer. I would certainly buy them again.

2020 Cyclone 3 axle toy hauler. Can definitely tell a big difference in how quick the trailer settles down over large bumps like bridge transitions. Things inside seem to travel better.
by: Rod05/09/2023
My toy hauler when loaded maxes out the 2 8000# axels. These Sumo Springs stop the over travel of the suspension and stops the spring sag that these trailers are noted for. The ride is more under control and there is less effect on the contents.
by: John 11/20/2022
We have a Grand Design Reflection 5th wheel with the refridgerator on the rear wall, and we kept having issues with the fridge doors coming open during bumpy travel, so we installed the Sumo Springs based on a number of other reviews that indicated it would restrict the trailers bouncing. Total success, we have not had the doors open since the install, and generally feel less bouncing as we travel. The trailer also has less bounce when stationary, an added benefit.

No problems at all, everything I said in first review remains, the refrigerator doors stay closed, despite some very bumpy roads, and we travel about 6 month each year in 5th wheel!

@John We're happy to hear that, thank you for checking back in!

We purchased these SumoSprings for our 2019 Heartland Fuel 250 knowing that they would not fit our leaf spring top plates, but I knew I could modify the mounting bracket to accommodate our RV. For anyone who has Dexter axles with shocks, you most likely have a 5-1/2” wide leaf spring top plate. If you are handy and have an acetylene torch or map gas you can simply heat and bend the inside bracket, drill a 1/2” hole and through bolt it to an existing hole in the top plate. I actually think this is a more secure install. Overall, it would be nice if there was an exact fit for our Rv, but it was an easy fix. Great product.
by: Steven 03/27/2024
Delivered on time and all the parts were there! They were easy to install and give the leaf springs the leaf springs the help they needed. Our camper has less felt recoil on bumps and pot holes which makes for an easier day traveling.
by: Larry 02/12/2024
Easy to install only a couple hours for both axles. A more stable ride and haven’t broke any leaf springs on these great American highways, by the way I installed them on a 38’ 5th wheel rv.
by: Silva01/22/2023
Installed on 2022 Jayco NorthPoint 310RLTS. Took them on their maiden voyage east on 138, south on 15 and 215 into Santee Lakes, Ca. Appears they have mitigated some of the rebound caused by springs, however don't expect it to eliminate all. There was still at times significant "bouncing" when transitioning bridge gaps or wonderful LA / San Bernardino Freeways.
Having had Timbren springs on my last truck and really enjoying the support, wondering now if I should have gone with them?
Bottom line, they WORK, just less than I would of expected. But then again, my expectations might have been too high.
by: Gary12/15/2022
etrailer provides quality products you can trust. Sumo springs made a big difference in the ride quality of my fifth wheel going down the road. It helped with chucking and takes some of the roughness out of the roads. Items in the cupboards are still a mess when we get to our destination, but less of a mess. Highly recommend!!
by: Cenvalleysteel11/04/2022
Very easy to install. The rough and uneven road and ride on our fifth wheel is vastly improved.

The SumoSprings work great made my trailer roll smoother down the road
by: Lynn10/19/2023
The springs do work I'm not sure how much they help. I take a trip across the USA every year. (10K miles) The roads are rough. I might be expecting too much, still have cabinet doors come open. I do feel they support the suspension.
by: JD05/14/2024
They were very easy to install and seem to provide additional stability on turns and over rough spots on the road. So far I would say they work as advertised. As usual etrailer is great to work with and shipping is fast.
by: Dan 11/14/2023
A must have for additional support for the leaf springs and makes the towing experience much smoother
by: Matt 12/18/2023
Installing the products went about as well as hoped. The hardest parts were keeping them on the desired location on the springs.
by: Christopher09/07/2023
I bought these believing I needed them for the leaf springs. I had set them aside so I could return them. Naturally, I forgot about them and a year later I contact the company and they tell me they won’t return them and suggest I sell them on social media. I have bought two leaf spring kits and due to my recent interactions I will never buy another set or recommend them to anyone. Very disappointed.
by: Timothy 10/20/2023
Installation was very simple. I didn't need to relocate a gas line which made the job even easier. It took me longer to crawl under the trailer than it took to install them. I have not towed yet, but I'm confident they will make a huge improvement on the trip from Michigan to Texas.
by: Dale 09/07/2023
If you own a camper, and you are planning on towing it on the crappy roads in America, you need these springs to cushion the ride and protect your investment. Install is fairly simple and straight forward. Just take your time and don't rush it.
by: Steve05/23/2022
So far so good. Easy install. Used trailer jacks to give me the 1/2-1” of lift required to install these. Definitely feel the difference in stability/lean when going around corners and hitting bumps. Will be putting a few thousand miles on this summer and these will provide some peace of mind knowing the suspension system isn’t taking as bad of a beating. A little pricey for rubber springs especially since I need four, but sometimes peace of mind comes at a price.
by: Thomas 04/16/2024
Service was great and product delivered on time as promised
by: Cameron11/17/2023
They came scratched up and worn like they’ve already been used…

Only used them for one trip
ended up installing larger slipper spring set up

I love my SumoSprings they work and they were easy to put on

Couldn't believe the difference in the ride of the trailer. I would highly recommend this product

- Spacing Required Between the Spring Plate and Trailer Bottom for the SumoSprings Trailer SpringsThe SumoSprings Trailer Helper Springs item # SS26MV require 5-5/16" - 6-1/2" of clearance. This is from the top of the spring plate to the bottom of your trailer. Since you are right at 5" you should be ok once you jack your trailer up and get the weight off of the springs. They are designed to be constantly engaged when you are using your trailer.
view full answer... - Comparing SumoSprings and Shocks for Trailers with Tandem 8K AxlesI really like the SumoSprings Trailer Helper Springs, part # SS33HR for underslung or part # SS26MV for overslung axles. The springs do a great job of adding stability to the trailer by absorbing road bumps more as well as reducing sway. A good example of this is when you get passed by a semi and a large gust of wind hits the trailer. This would normally cause the trailer to rock side to side creating sway but with the springs, they will compress when the trailer leans to one side which...

view full answer... - Will Using Leaf Springs With A Different Amount Of Leaves Be Okay On My 2018 Vanleigh 5TH Wheel? The number of leaves on a leaf spring is not the only determining factory in the amount of weight it can handle. The thickness of each leaf as well as what the leaf is made out of can affect the weight rating and performance of the spring. The Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 does use 5 leaves that are 3/8" thick. Each spring is rated for 3,500lbs which is 7,000lbs per axle. This kit upgrades your suspension by allowing the axles to act independently of...

- Trailer SumoSprings For Grand Design Reflection w/ 5k Axles & Leaf Springs Over AxleWe do have the trailer SumoSprings for your Grand Design Reflection with 5,080 lb GAWR axles and with leaf springs over your axles. What you need is the following: - SumoSprings Trailer Helper Springs # SS26MV The # SS26MV are for 5k to 8k overslung axles (the leaf spring is over the axle) like yours. This is a single axle kit so for a tandem axle like your Grand Design you would need a quantity of two.
view full answer... - SumoSprings For 2017 Forest River XLR Thunderbolt Your 2017 Forest River XLR Thunderbolt should have 3 inch diameter axles, though I do recommend verifying that. If so, there are SumoSprings you can use, with the correct option simply depending on if your toy hauler's leaf springs are underneath the axle or over the axle. If you're not sure you can just take a look under your trailer and it will be easy to spot if the leaf springs are sitting over or under the axle beam. - Leaf Springs Underneath Axle: SumoSprings Trailer Helper Springs...
view full answer... - Will SumoSprings Trailer Helper Springs Increase Space Between Frame and AxleThe SumoSprings Trailer Helper Springs typically install compressed so they do tend to provide more space between the frame and axle in most cases but not by much and this is not really the goal of the system. If you don't have enough space between the frame and axle then this may be due to worn out leaf springs so I recommend checking this but I have attached the SumoSpring options below which are based on axle type and capacity.

view full answer... - SumoSprings Suspension Enhancement Kit for Trailer with Tandem 5,200 lb Lippert AxlesThe SumoSprings kit part # SS26MV would work great on your tandem axle trailer that has 5,200 lbs and cushioned equalizers. This will give you additional support and smooth out the ride quality as well. This kit is also listed as TSS-107-47 which might be where some of the confusion comes from.
view full answer... - Will SumoSprings Trailer Helper Springs for 5-8K Axles Work with Triple Axle TrailerYes, the SumoSprings Trailer Helper Springs for 5-8K Axles part # SS26MV for overslung or part # SS33HR for overslung will work on a triple axle trailer. You'll need one kit per axle for a total of three kits. There would be no difference between the single, tandem, or triple axle installs. These springs will do a great job of absorbing road shocks while makes for a smoother haul. They will also work to increase stability by reducing side to side sway. .
view full answer... - Correct SumoSprings Trailer Helper Springs for a Alliance Valor 42V13The correct SumoSprings Trailer Helper Springs for a Alliance Valor 42V13 is part # SS26MV if your leaf springs are over the axle or part # SS33HR if they are under. I don't know if you have underslung or overslung axles so you'll just need to take a quick peek under the trailer before ordering.

To verify if the SumoSprings Trailer Helper Springs # SS26MV will fit your 2022 Dutchmen Astoria 3173RLP you will need to measure the distance from your spring plate to the trailers frame. You will need between 5-5/16" and 6-1/2" for them to fit and work properly. As I have no way to see exactly what parts are installed on your Astoria I would need photos and measurements for any components you wish to replace such as the hangers.

There are two sets of SumoSprings that will work with your Coachmen Freedom Express 257BHS which one you need will depend on the orientation of your axles and springs. These are sold as a pair so you will need one set per axle. I have listed both options below: If your axles sit below your springs you will need the SumoSprings Trailer Helper Springs - Overslung item # TSS-107-40.

They do a great job of absorbing road shock while also working to increase stability by reducing side to side sway.

The only equalizers available for slipper springs are just standard setups unless you're looking at a complete overhaul with the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks # RM-2470-2580. Aside from changing out the equalizers we also have the SumoSprings...
view full answer... - Suspension Enhancement for Toy Hauler OptionsWhile we don't have add-a-leaf kits for your trailer we do have suspension enhancement options that will do a great job providing additional suspension support. If you have an overslung axle setup we have the SumoSpring part # SS26MV for if you have a 5k to 8k axle, part # TSS-107-40 for 3k to 5k. If instead you have an underslung option you would want the part # TSS-106-40 for 3k to 5k or part # SS33HR for 5k to 8k. Underslung means the spring is under the axle and overslung is opposite.

Plus, Andersen couldn't say if their weight distribution system was compatible with the Gen-Y hitch as they haven't been tested together. I'd concentrate on the suspension of the trailer itself. To improve the ride of the trailer,...

The kit includes a line relocation kit in case there's a wiring harness, water or gas line in the way that would interfere with the installation.

To determine the correct kit for your trailer you'll need to know the axle capacity and whether or not your axles are overslung or underslung. If your leaf spring stack sits above your axle then you're overslung, and if your leaf spring stack sits below the axle you're underslung. The axle capacity can be found on the axle tag that should be stuck directly to the tube of the axle. If not...

Ok it’s been a year and I have to say this product is definitely worth the investment. After taking it on a month long journey from Oklahoma to California I noticed improved handling especially along winding narrow roads. The trailer tracked well and I noticed less jolting. I also noticed the body roll diminished when in high winds or being passed by bigger trucks. Great product definitely recommend if you do allot of long hauls.
