4,600-lb Capacity. Upgrade your rear suspension by installing these helper leaf springs above your Coachmen Leprechaun Motorhome's factory leaf springs. They significantly reduce sway and prevent sagging, which is perfect for those who often tow or haul heavy loads.
Features:
Specs:
These additional leaf springs add support and sway control to your existing OEM suspension. Just bolt on SuperSprings over your existing factory springs, and they automatically work when you need them. As the factory spring flexes, a roller at each end of the beefy helper spring reacts to engage the helper spring and to provide extra support. The springs help to better distribute cargo weight throughout your existing suspension, channeling that weight to the points on the frame that are designed to support heavy loads.
Placing these leaf springs above your factory springs helps to keep your OEM springs from twisting, so the SuperSprings act like a sway bar, reducing the body roll that makes driving more difficult and dangerous. With these helper springs, driving is safer and easier when it's windy, when your vehicle is rocked by a passing semitruck and when cornering. The springs help to reduce sway by up to 30 percent. SuperSprings also allow more wheel travel in the rear suspension when they are under load, so they maintain traction and ride comfort better than rubber or polyurethane bumpers. That means they're great for drivers who frequently tow.
You can also customize the level of support provided by SuperSprings. For most models, the shackles that attach the helper leaf springs to your existing leaf springs have several installation options:
SuperSprings are a maintenance-free, low-cost alternative to air spring systems, which require constant monitoring and air pressure adjustment. These helper leaf springs respond automatically to the load you carry, so there is no crawling under your truck to adjust them. You'll also reduce wear and tear on your suspension, brakes and tires, which saves you money. The bolt-on installation means that they are easy to fit - no drilling required. For some models with factory springs located above the axle, the kit includes poly spring pads. These dense polyurethane blocks seat between the top of the factory springs and the underside of the SuperSprings to prevent shifting.
This suspension stabilizer kit is perfect for trucks towing fifth wheels, campers and gooseneck trailers.

I installed Sumo Springs on our 06 Xterra right after we bought our Casita 17' trailer. The back of the X squatted a bit more than I liked. I had also noticed before some tendency to bottom out if the car was full of people and stuff. These ingenious devices are a perfect solution for me! They are about 3/4" clear of being engaged with the axle when unloaded, so the ride is not overly affected, but progressively take up some of the weight when the back end starts coming down with load. It now sits very nicely with the trailer connected, no weight distributing hitch and stuff in the back, and no more bottoming. We've put a good number of miles on the X in the last year, towing and not towing, and they are still doing the job.
I should note, the back of my Xterra is lifted about an inch with AAL springs. If that were not the case, the Sumo Springs would be engaged all the time. That will vary with vehicle.
I will also note that they are non-adjustable, unlike airbags. I kinda like that, I didn't want to mess with adjusting air pressure and such. But once they do start kicking in as one or both wheels travel, they do stiffen it up quite a bit. I mean, there's no way around that; you can't take load without stiffening the suspension. As such I think they inhibit upward axle articulation a bit when 4-wheeling, but for us that's not a big deal. Since they do not connect to the axle, they don't affect downward articulation at all.
The pics are shortly after installation, one with the car unloaded, and two with trailer and gear loaded up.
I believe it’s going to be a great addition to my truck when pulling our RV. Looking forward to a smoother, more even ride. I left the 2x4 blocks in overnig8ht and drove around to ensure a good seat for the springs.
Very easy installation in about 20 minutes. Very ingenious concept as opposed to bolt on leaf style helper springs
These Sumo Springs were easy to install, even for a 70 year old guy. I tow a 7,000lb camper and even tho I have a nice WDH I still had som sag on my Tundra. These helped level it out when towing and got rid of “some” of the bounce. They were really a godsend when I overloaded the bed with about 2,000lbs of pavers. That weight squished the Sumos significantly but the truck drove and rode great. Better and less expensive than air bags.
The SumoSprings Solo came to the RV Resort today. I installed them on my Titan SV today in less than an hour. Only drove 10 miles with them and they are what I was looking for. In my opinion it was a needed upgrade and thumbs up!
I have had these on my Jeep Gladiator for over a year now and I still like them. Sumo Springs really help with sag when towing my Scamp camper trailer and when the truck bed is loaded with stuff. When it is cold outside they are stiffer and I can feel when they hit the stops on hard bumps. Sumo Springs are a very easy overload spring option with factory lift.
Gave it 5 because of ease of install - note they use SAE threads 9/16, truck frame and oem is metric 15mm wrench. Makes no difference but don't use oem nuts on spring. I installed all shims supplied and this left about 3/4" gap so hoing its the best for my needs. Easy to reduce if needed.
While these worked great for the first few months and helped level the load, they have now become deformed and squished out of shape permanently. We have a slide in camper that is on the truck for only for trips otherwise the truck is unloaded and off the bumps. I did not expect them to deform so much, and so easily after only a year of use.
Fairly simple to put on but need to work around the brake lines and bed cross beams. I haven’t tried it yet with weight. I have enclose pic of drivers side. Maybe can’t tell from the pic but there is space and flexibility around the lines around bolt.
Straight forward, simple, replacement for OEM springs. These springs make contact with the lower arms all the time and definitely help dampen the bounce effect from a heavier steel bumper. Any rolling effect from uneven roadways and turning is also reduced, it feels the vehicle is more stable. For my situation, this is the first step to take before considering replacing shocks, etc., and is very economical. I'll give it more time, but I believe this is all I'll need to do. Thanks etrailer! Quick shipping!
Very impressed. Stopped the Tacoma lean. Also helped with the trailer. I do use a distribution hitch I bought from etrailer. Just bought the sumo spring for other applications. Those little bitty factory bumps where junk. These help with lean, and off road hard bounce.They are great.
First off, these won't fix worn out suspension components, they are designed to improve ride quality by reducing sag/porpoising, especially on heavier vehicles.
Our 2010 Roadtrek 210P (75k miles) is a great rv but essentially a big heavy tub going down the road. Has the tendency to lean and wallow front to back. New shocks and all suspension is good, as mentioned make sure that stuff is all in good shape.
Pics show the oem stops vs the SS stops. Big difference - you may assume ride gets harsh but not the case. The oem stops were very tired and didn't do much. The preload on the new SS stops is just about perfect - any weight changes are very progressive which takes the harshness out of the ride. I didn't really see any change to ride height either.
Road manners are improved, there's a bit more resistance to lean, but the main difference is that the front end doesn't try to change height as readily with the back end.
Not a big deal to install. Youbdont need to pull the wheels, just turn them side to side to get to the stops. Pop out the old stops and clean the retaining cups with a wire brush and some brake clean. I used syl-glyde on the new stops to help get them into place. I also used a crowbar under the stop to push it into the cup while making sure the 4 tabs captured the top of the stop. Final step was to lower the van and give it a drive, then check to ensure the fit was good. The key here is to clean the cup first and use a bit of lube on the new stop.
Very pleased and I'll be installing SS on the back end soon. Yup, they're pricey but they are good quality with a limited lifetime warranty.
Great upgrade from the oem jounce. Easy to install with 2 people but follow the install video and use a 1/2" deep socket with a long extension. Took about 30 minutes.
So glad I found these! Best upgrade for my Winnebago Era Touring Van. Simple to install. I only needed a floor jack to get it done. Van doesnt ride like a boat in a storm anymore. Highly recommend for Sprinter vans.
These springs are amazing! They helped tremendously pulling my landscape trailer with all my mowers. I picked up a tractor impliment that I would normally bring a trailer for, but decided to put these springs to the test. Couldn't believe how good my truck rode and handled with 780lbs at the rear of my bed! These springs have exceeded all expectations.
I will say that I initially put the spacer, but found it effected my ride to much so I pulled it. Afterwards it rides like stock.
These do not fit a 2006 ram 2500. As you can see in the
Photo the bolt holes are WAY off. It also does not sit over the axle tube. My only option at this point to use them is to make a 2nd bracket to bolt the helper too. Very disappointed.
We pull an off-road teardrop camper with our 2013 Toyota Tacoma and were looking for a little help with the rear end sag when we have that hitched plus putting some weight in the back of the truck (firewood, water, etc). Our Tacoma is lifted (2.5") but the lift kept the stock springs with an added Deaver leaf to help with the notoriously soft Toyota springs. However, with the shell and ~300 pounds of weight in the back, it still sagged, especially with another 250 lbs of tongue weight from the trailer. The Sumos have eliminated that sag, even with bigger loads in the bed, eliminated body roll (also notoriously bad with Tacomas) and didn't destroy the ride for day to day driving. There might be a slight bit more stiffness when hitting speed bumps, but definitely not bad at all. If anything, I would say it IMPROVED the ride and handling.
The springs themselves were simple to install, less than half an hour start to finish. Some reviews have said they were bumping the frame after installing but we had about 1/2" gap on both sides. The only "specialty" tool would be a torque wrench capable of 90 lbs to get it to spec.
We considered Firestone air bags but after talking with the reps at e-trailer, we decided on these and couldn't be happier. Reasonably priced (half the price of air bags), no maintenance, great customer service...can't argue with anything at all.
2015 Frontier Crew cab Desert Runner (purchased the yellow Sumo Springs). Easiest install ever! 18mm deep socket and long breaker bar for breaking nuts loose. Removed factory bumpstop, install sumo bracket and retighten U bolts to 58 foot pounds. After installing both brackets, lifted back of truck up 4 inches to install sumo spring with blue lock tight on bracket bolt, tighten sumo spring onto bracket and lowered truck off the jack. Overall it raised the back of my truck bed 1 inch. Ride is stiffer with no bed roll in the turns. Loaded my 24 foot travel trailer with load leveler- equalizer bars and gained 3 inches (less “squat”.) Truck is level now vs nose high (without the sumo springs). Definitely an upgrade that was needed in 2015 when I first bought the truck!!!
After a year, very good suspension enhancement. The initial install was a pain only because I sheared the factory bolt in the original bump stop trying to remove it. Had to drill out and re-tap for new Sumo spring bolt.
Just installed the Sumosprings on my 2022 Tacoma,easy install, took about a hour.Truck rides the same with no load on it and will see how it does next time I tow the trailer.Shipping was fast and well packed.
These springs work great.
Pros: Towing feels so much more stable, controlled and secure. No more extreme bouncing over large bumps. Makes towing ride feel more comfortable.
Cons: Does make unweighted travel a bit more active and rough. Small bumps normally absorbed by suspension tend to become more pronounced. This might be fixed by medium duty jounce spring, but there could be a potential loss of usefulness with a heavier load. Minor drawback compared to the pros.
Very straight forward installation. Simple. very noticeable difference under load. Towing with the gooseneck also an improvement, looking forward to the longer road trip test. So far pleased with the product and results
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.
This is what was needed to keep the truck level when the 5th wheel camper is attached. Works great better ride. 22Chevrolet HD DURAMAX. Camper is a 40 ft. 5th wheel
