SuperSprings diagram of roller and shackle system for extra leaf spring

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.


SuperSprings leaf spring installed on a vehicle

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.


Truck before SuperSpringsTruck after SuperSprings

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:

  • For greater support and ride height when your suspension is under a constant load or if you have an older automobile with some spring fatigue, install the helper springs using the upper bolt holes
  • To maintain the factory ride and reduce the effect on your ride height, install using the lower bolt holes
  • To balance support, height, and ride comfort, install using the upper hole on one end and the lower hole on the other

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.

Video Transcript for SuperSprings Custom Suspension Stabilizer Review

Speaker 1: Today we're going to be taking a look at the SuperSprings lines of custom suspension stabilizer and sway control kits. You'll want to use etrailer's fit guide to determine the correct kit for your vehicle. Here's what our SuperSprings are going to look like once we have them installed. Now these are going to give us the support we need whenever we're hauling a heavy load or towing a heavy trailer. Typically, whenever we're hauling something extremely heavy our suspension wants to flex a lot and our back end sags down. Well these are going to provide us the extra support by activating whenever our suspension flexes, the rollers on the end of our leaf spring are going to activate our helper spring and provide us that extra support.

But also still giving us a nice ride when we're not towing something heavy, because it's going to deactivate those springs and still have a nice comfortable ride.And since they are attached to the front and back of our factory leaf springs, it's also going to act like a sway bar and it's going to prevent our leaf springs from twisting. Giving us a lot more stability when we're driving down the road. The multiple notches in the end here are going to provide us with a little bit of customization, depending on how much support we need. If we need more or if we just have a little bit of spring fatigue in our truck, it'll give us that little bit of lift so whenever we're towing something we don't have quite as much sag.We have a water tank in the bed of our truck as a heavy load or to simulate the tongue weight of a heavy trailer or a fifth wheel. So as I take the truck through my test course, I can definitely tell that there's a load back there.

The engine doesn't seem to be straining that much, but the bumps are extremely harsh and I can definitely feel it resonating through the seat. When I come to the slalom course and I'm going through the turns it definitely has a lot of body roll and I just generally feel like I need to slow down because it feels like it's leaning a lot and it's not responding quickly enough to the turns.The SuperSprings installed and I have the same load back there. When I'm driving through our course I can immediately tell a difference. The bumps aren't as harsh because the truck isn't sagging down as much and there's a little bit more support back there. But really where I tell a big difference is through the slalom course.

It definitely feels way more stable and even taking the turns going in and out, it just feels like it really wants to stick to the ground a lot better and just generally wants to go faster.Compared to airbags, these are a maintenance free option with no tubes to run or air pressure to maintain. Similar to airbags you can customize the level of support provided. Unlike airbags however you do this during the installation and set it one time rather than on the fly adjustability you get with airbags.And that completes our look at the SuperSprings line of custom suspension stabilizer and sway control kits.

Review from a similar SuperSprings Sway-Control in Vehicle Suspension


The kit looks really good but I can’t figure out how to install. Enclosed are two photos showing my van suspension and the parts your sent. The instructions do not show my van with only one spring. Can you advise?????????????? Thanks. 603418


Comments
If you look at page 4 of the instructions which Ive linked for you, you can see photos showing a single leaf spring set up just like whats shown in the photos you provided thanks for the photos!. Im guessing that page was not included in your instructions for some reason.

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. 226686

Review from a similar SuperSprings Sway-Control in Vehicle Suspension


Product does just what it says it does. Installed them on a Thursday and towed with them that weekend....... and they did a great job. Handled the tongue weight of my dump trailer better. I did notice a decreased amount of "wave" effect when you are in tow and your heavy trailer hits a bump or swale in the road; and transfers that energy to the truck. Sorta feels like you got a heavy tail that someone is tugging on. This was significantly reduced and made for a pleasant ride Later on Sunday then threw a load of firewood (no trailer this time) in the bed full; and in comparison of a previous haul with wood the truck did not sag as much. My truck config is stock, double cab w/ 8' bed 4x4. I did not notice a stiffness in ride with and empty bed or no trailer in tow. Seemed to be just fine. Slightly raised the rear but with the long truck it is hardly noticeable. One part of the installation was a little difficult, when it came time to compress the leaf it was a bit of a chore. I did have a 5" c-clamp but it was getting tough the last few inches to get the roller underneath the stock leafs. If I had a special leaf spring clamp tool as shown on some of the youtube vids I would have been done in about a 1/2 hour but with out this tool it makes the compression part slow. 145702

Great item!! The Supersprings performed just as described. No more sag in the suspension and the benefit of better control. Installation was an hour with the help of an experienced mechanic and the right tools. If it wasn't for removing of the bumb stops on the axle, installation would have been faster. Expensive product, but it is a quality product and made in the USA. After install, the springs raised the rear of the truck about 2" to 3" when unloaded. Best part is that the springs didn't cause the truck to ride rough when unloaded. 21988

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. 505177

Review from a similar SuperSprings Sway-Control in Vehicle Suspension


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". 316290

Review from a similar SuperSprings Sway-Control in Vehicle Suspension


This product is a must if you are looking for a pleasant ride empty, yet still have additional capacity when you need it. I purchased it because I haul a Lance 1062 camper and was not pleased with the air bag setup I had been using. The air bags would handle the load just fine, but I got a lot of side to side motion while going around corners. I even set each air bag up independent of the other. The SSA15 kit eliminated the side to side motion. It really does act like a sway bar. I recommend you remove the rear tires when you install, it will make it much easier. 485410

Review from a similar SuperSprings Sway-Control in Vehicle Suspension


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. 557350


Comments
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.

Review from a similar SuperSprings Sway-Control in Vehicle Suspension


Very pleased! There are two settings, but I prefer the heavier capacity setting and higher in the rear feeling. It has made all the difference in the world with my long wheelbase 2002 Chevrolet Astro Van. I really do not feel that it has changed my ride comfort that much, very little, if any. I always have some kind of load on the van, whether hauling cargo in the van, or towing a trailer, that my ride is still as smooth as always. But, the remarkable thing is, that now my rear end isn't sagging to the ground like it always use to be, even without a load! I'm super pleased and would recommend these springs to everyone for the reasons I've shared above. 563128

Product was delivered quickly and in good condition. These springs worked great on my 2003 F-150. They did add about 1" of lift to the rear end of the truck, but make for a level ride when trailering my boat or equipment trailer. 162484

Superspring purchase was right on the mark. Gave George J. all the info on my truck, rv and what I was experiencing. He suggested the SSA5MTKT springs that they should take care of my problem. I installed them in 45 minutes, hooked to my rv and made a pull. I was able to pull at 65 and 70 mph with minimal bouncing and rocking. An increase of 1" in loaded ride height and 10-15 mph was perfect. Thanks George J. and the staff at Etrailer.com 229763

Review from a similar SuperSprings Sway-Control in Vehicle Suspension


These helper springs worked well. My truck didn't sag nearly as much with similar loads in it than it did before. Probably raised it around 4-5 inches when loaded and about an inch when not. Only complaint is the bolts holding the product to the adapter for a spring over axle setup are not of a high grade. They broke, but I may have overtightened them. I replaced them with some grade 8 bolts from the hardware store. They are only needed to hold the new spring in place when the vehicle is raised off the ground. They don't affect the performance of the product. 247201

  • Rear Helper Springs for a 2016 Ford Transit T250 Cutaway with KUV Utility Body
    The chassis on your 2016 Ford Transit T250 cutaway is the same as the cargo van models so you can use SuperSprings # SSA11. But what I recommend that will work just as well and that costs less is the SumoSprings # SSR-121-54. They will help keep the van level, absorb road shock, and reduce sway or body roll.
