1,500-lb Capacity. Upgrade your rear suspension by installing these helper leaf springs above your vehicle's factory leaf springs. They significantly reduce sway and prevent sagging, which is perfect for towing or hauling 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 semi, and when you are 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.

1,500-lb Capacity. Upgrade your rear suspension by installing these helper leaf springs above your vehicle's factory leaf springs. They significantly reduce sway and prevent sagging, which is perfect for towing or hauling heavy loads.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 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.
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
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.
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.
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.
2019 Silverado Trail Boss
Easy Installation and definitely helps with sag when loaded, however, can be noisy on bumps and turns when unloaded due to its "floating" design. it also raised the rear end of the truck by another inch or so.
If I had to do it over again I would probably go a different route
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.
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.
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 springs were easy to install with wheels still on the vehicle. They did increase the overall height of the rear end of the truck by 1-2 inches. I noticed an improvement in ride with my travel trailer.
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.
I put these springs on my 2019 GMC and liked them so much, I bought another set to put on my 2017 GMC.
Took me about hour to put on. I removed the wheels, I think it was Easier
with the wheels off.
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.
very easy to install!! i haven't had had a load on the truck yet, but i'm sure they'll work out great!! a friend has same set his F-150 and there working great for him !!!
Very easy install , used this product on previous vehicles and they do the job. etrailer is an excellent company to deal with!
WORKS WELL. HANDELS MORE TONGUE WEIGHT AND PAYLOAD. EASY TO INSTALL,MAKES THE TRUCK MORE STABLE. HAPPY WITH THE PURCHASE.
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.
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.
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.
The installation was easy and straight forward. I removed the tires which gave me great access to install the springs. The ride is smooth and stable. I would recommend this product to others.
Product arrived quickly and install was fairly smooth once I got the C clamp attached the correct way to flex the spring into position.
Just installed and I loved how easy it was took 30 min tops. I expected a much stiffer rear end with the bed empty but was pleasantly surprised at how smooth the ride remained. I did notice a more stable and responsive feel while driving. All in all super impressed with the product so far, shipping was fast (ordered Saturday and received Wednesday, in canada) everything I needed was in the kit and it only raised the rear end up about 1/2".
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.
