When you’re towing or hauling a serious load, sag and sway can make the drive tough. This SuperSprings Custom Suspension Stabilizer and Sway Control Kit adds up to 1,400 lbs of rear-end support by mounting helper leaf springs above the factory springs. As the stock springs flex under heavy weight, rollers on each end of the SuperSprings engage automatically to keep your truck level, prevent bottoming out, and deliver steadier handling and braking on every haul.
Wind gusts, passing rigs, and tight corners can twist your factory springs and push your truck around. These helper springs work like a built-in sway bar, reducing body roll by up to 30 percent. By stabilizing the OEM springs and keeping them from twisting, they make towing or hauling through curves or windy stretches safer and more comfortable with less rocking or sway.
Not every load is the same, and this system lets you tune it to match. The shackle design offers several bolt positions so you can choose more support and ride height for constant heavy loads, maintain factory ride for everyday use, or pick a balanced setting in between. Once installed, the SuperSprings adjust automatically to your payload—no air lines, tubing, or compressors to deal with—so you get the support you need without extra maintenance.
Installing extra support shouldn’t take all weekend. These helper leaf springs bolt directly above your existing factory springs with included poly spring pads for certain setups that need them. There’s no drilling required—the dense polyurethane blocks seat firmly in place to prevent shifting. Once mounted, the system requires no upkeep and helps extend the life of your suspension, brakes, and tires while keeping your truck sitting right and ready for every trip.

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.

The product works great after a year. I highly recommend the super springs for any heavy loads. After they are installed you never need to worry about the load.

Thanks for your feedback, Bob! We’re glad to hear the shackles made a noticeable improvement in your ride quality. We appreciate you pointing out the fitment challenge and the issue with the instructions, I'll pass it on to SuperSprings.

They are working out fantastically! Now we dont bottom out and damage the sewer dump. Weve been all a long road trips and nothing is bothering us now in regards to suspension.

Works great towing and seems to help with some sag and roll. I use them along with airbags so towing my fifth wheel is now worry free.

That is great to hear! I am glad this addition has worked well for your setup. What RV do you have that you added this too?
