When your bed or trailer weight makes the rear sag, these helper leaf springs pick up the slack. The SuperSprings Custom Suspension Stabilizer and Sway Control Kit adds up to 1,500 lbs of rear suspension support by bolting above your factory springs. As your stock springs flex under load, rollers at each end engage automatically to lift the back end and keep your ride height level. There’s no air pressure to monitor or tubing to maintain—just consistent load support whenever you need it.
Crosswinds and corners won’t throw you around like before. These helper springs work like sway bars by keeping your factory leafs from twisting. The result is up to 30 percent less sway and a more stable ride when wind, passing trucks, or uneven turns try to move you around. Your truck stays planted and easier to control while towing or hauling heavy cargo.
You can dial in how much lift and firmness you want with the adjustable shackles. Mount them in the upper bolt holes for maximum support and extra ride height under constant heavy loads, the lower holes for a near-factory ride, or a mixed setting for a balance between comfort and stability. Each setup changes how much the helper spring preloads against your existing leaf pack, so you can match it to how you use your truck.
Getting this system on your truck doesn’t require special tools or permanent mods. The SuperSprings kit bolts right onto your existing leaf springs with included shackles and hardware—no drilling required. Poly spring pads sit between the OEM springs and helpers to prevent shifting on certain models, and once installed there’s nothing left to adjust or service. Just load up and drive knowing your suspension is ready for the weight.
These helper springs share the load with your stock suspension so brakes, tires, and factory leafs last longer. The dense polyurethane blocks and heavy-duty steel leaves handle constant flexing without leaks or wear points that air systems can develop. With a limited lifetime warranty and 30-day satisfaction guarantee, this setup is made for years of hauling without extra maintenance.

The system works great in keeping sway under control. Big trucks do not move my rig hardly at all. The ride is hard. My wife feels very little bump. She has a bad back. I love the system.
installed my new springs with no great difficulties. just wanted to eliminate the normal trailer drop ,causing headlights to be high , bothering other people. i have only driven for a short time , but i can feel the difference in both ride and sway. they don't change unladen ride so everything is smooth. again easy to install and they do what they are advertised for.
The product looks good and it set the rear end of our truck up a little. My wife and my friend sat on the tailgate to give us an idea what kind of ride we might get and the body sat down just a little with that weight. The instructions could definitely be a little better due to that we looked on [line] for more information.Can't wait til I pull the 7500 lb trailer next week to see the ride and if it took the sway out. Best I can do so far. Will add photos when I test this out and two of my friends want to know how this does.
Put them on a 2010 f-150 and when I put a load on the truck the super springs hit the frame. Worst money that I have ever spent
Does exactly as advertised but it is noisy at times when braking or accelerating. When I buy a new truck I will be putting a set of super springs on it.
This is the 3rd set of supersprings I have purchased. I am completely satisfied with each set. I have a set on a 30 foot class C motor home and it solved a swaying problem plus giving a better ride. I had a set on a F 150 that I sold, so when I got a new pickup I needed another set. The supersprings completely solve any towing and hauling issues. I have a Ranger pickup that I tow behind the motor home and haul a motorcycle in it. The motorcycle makes the little pickup sag so I will be ordering a set of super springs for it.
Very easy install , used this product on previous vehicles and they do the job. etrailer is an excellent company to deal with!

Fantastic
Part arrived and looked great. Very easy to install.
Only two things that can be fixed is that the springs only go on one way and they are not marked front/rear, and its not real clear how the the rubber spacer is used.
I installed these on a 2005 ford F-150 Supercrew and I pull a 30 foot travel trailer.
I have installed air bags to level the truck/trailer, but at 50psi the kids in the back seat got beat up due to the poor ride. I'm hoping these springs will level the truck/trailer and give us a better ride.
We going up north this weekend and I hope i can re-post how the trip went.
I usually never give a five star rating, however these were very easy to install, and have increased the spring load capability. I have found that the truck does not sag as much as before and the ride is better when pulling the camping trailer. would strongly recommend if you do not want air bags.
After trying leaf spring helpers and switching them out for super springs what a night and day difference. They've held up great! Made a huge Improvement
Both the Drawtite hitch and the super springs went in fairly trouble free. I don't follow directions. there is a better method to install the hitch. Lift the front of the bed up four or five inches. Then preassemble the hitch and slide it over the frame. Center in the predrilled holes and tighten the bolts.
It a good product for 2017 Ford f150 except 1 factor that it had to mounted more toward the rear and the no bracket to hold it in place if I get a tire rotation or lift the vehicle from the rear the spring roll away and need to clamped while lowering the vehicle. I contacted Super directly to there warranty department and they sent me a lock down kit. It also Lifted the truck about a inch on low setting so I'm sitting at 39 inch in rear.
It does what it's supposed to do for a cheap price.I got rid of them and put on air bags......night and day difference, bags cost more but in this case you get what you pay for.

Air bags are often easier to adjust and is better for rear sag. The Air Bags I would recommend for your 2020 Chevrolet Silverado 1500 is the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers - Rear Axle Part # AL88288. You can use the Air Lift WirelessAIR Compressor System for Air Helper Springs - Remote - Bluetooth - EZ Mount Part # AL74000EZ for a wireless control of your air bags.
Took me about hour to put on. I removed the wheels, I think it was Easier
with the wheels off.
I installed the springs in conjunction with the SumoSprings on my 2017 Sierra 1500 4X4. I took the wheels off and start to finish was less than an hour and a half. Very well thought out design and easy to install. The initial setting raised the back end 1.75" and was not quite stiff enough so I moved the front bolt up to the top hole, this gave me 2-1/4" lift at the wheel wells. It took the weight off the overload springs that was always loaded before. With the camper (8000 lbs) and distribution hitch the truck was barely on the overloads with the SuperSprings and then the SumoSprings kicked in as well. Between the two upgrades we towed 900 miles after the install and handling and body roll were drastically improved. USA made product that is well designed and made. Would definitely recommend either the SuperSprings or the SumoSprings as a must have upgrade if you tow a lot with a lighter suspension vehicle.
I purchased super springs for my 2018 Silverado 1500. It raised the rear about 2 inches. Attaching my 1/2 ton lite fifth wheel dropped the truck back to level. After a roundtrip from NC to MA, I found the decision to purchase the super springs was the right choice. With 18 wheelers passing by me I experienced no sway. Best of all, no maintenance is required for this addition. When towing my 5th wheel w/o the springs, I experienced a little sway and bobbing and the front of my truck was noticeably higher.
I love these booster springs! The truck sits better and rides better when pulling my camper or hauling other heavy loads. I am very pleased!
I installed these on my 2013 F150 they fit great lifted the truck about 1inch but did not affect the ride. When I pull my 8X17 fish house the truck sits nice and level now. Other sites recommended the install kit which is not needed on this vehicle. E trailers was great to order from. Shipping was a week early.

Still stand by this product, all of my future trucks will have super springs. Still a nice ride and no noise.
The spring system itself is a great product, but I’m using these on a 2021 F-150. In 2021 ford went to a mono spring design that has less arch in its resting state. I called superspring prior to ordering to verify this was the correct product and was told this was the one. After installation the springs walked all over the place under normal driving conditions and had to be constantly removed and re-situated. I’ve since had to use industrial glue to attach the spring to the rubber block that it rests on and that has solved the movement issue but in my opinion this is something that should not need to be done if the product was actually made for my vehicle. however, from a functionality standpoint they work well once they are actually held in place.

The manufacturer will reach out to you.
After having used partial and full ‘add-a-leaf’ kits on fleet trucks in the past, I was willing to give these a try.
Having missed the stiffness of a 2500 rear end and having put 125k on a 1500 with a topper/camper shell, this was the progressive stiffness I was looking for.
The vehicle sits 1.5” higher at the rear, isn’t overly stiff, alowing the Bilstein shocks to continue to do their job, properly. Adding the tow behind camper, along with a loaded bed, far less body sway without a compromised ride.
I also utilized the SumoShocks (front and rear), for some time and I love them. Having everything together, as a package, works great for me when towing, the bed is loaded down and when I’m traveling 2hrs at a time from place to place, as a highway truck.
This will take some serious C clamps (8” from hardware store) and some mechanical aptitude if using a jack and stand(s) in the garage. Overall, not too strenuous or hard. Nothing intimidating.
I’d definitely recomend to anyone wanting to help tired leaf springs or when reducing body roll.

The Sumo Springs continue to provide wonderful results. Many friends with 2500 trucks and onlookers at campgrounds are amazed when we tow our 38’ trailer weighing around 8k lbs when loaded, plus the truck bed loaded with wood and bikes, etc, the family and dog in the cab... All with little to no squat! The ride stays consistent to the 2500 feel I like and it allows me to keep my ol’ beater with high miles and a few thousand miles. I definitely recommend the Sumo Springs and their products. Again, having had their products on other vehicles with more than happy results, I don’t foresee ever purchasing a vehicle and not, at the least, including the rear bump stop supports and adding the leaf kit from there.
Great product, fast shipping. My only complaint is the package was delivered with both ends of the box ripped open. Luckily no missing components
These springs improved the ride considerably , less roll on corners with the slide in camper on and wheel hop on rough roads . In general the handling was much improved.
Had a pro install them to the center hole like Manufacturer suggest, rides a little firmer which I like not sloppy, Have not towed yet but looking forward to it! Great products and fast shipping.
Just put on super springs 2019 f150 for towing a camper that is awful in wind. The installation was easy. Hoping the springs help with a stable ride. I will update when I get the camper out of storage.
While use the middle setting it only gave it a slight lift with a minimal unloaded bounce. Usually never overload the trucks maximum capacity but needed to for a short distance and with approximately 1300 pounds in the bed, the truck didn't squat at all.

The springs worked great, reduced sway and gave better wheel control
