3,400-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:
Note: This kit is designed to fit a vehicle with factory top overload springs. As shown in the picture above, a top overload spring sits above the factory leaf spring pack.
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.

Correct product shipped promptly. Shipping carton was completely open and nearly ripped in half, but all components survived and made it to me.
Installation time was about 2.5 hours. I'm not a mechanic by any means, but overall it wasn't too bad. A couple of things for F250 owners (mine is a 2011):
1. You will have to remove a brake line bracket on the driver's side to install the rubber spacer. I re-installed the bracket onto one side of the U-bolt that is installed on the spring.
2. There is no way to insert the roller bolt on the front of the driver's side spring - not enough clearance. I had to completely remove the swing arms, pre-install the roller bolt, and the piece it back together once in place. Wasn't hard, just took some extra thinking.
3. The thing I was most worried about was compressing the spring in order to insert the rollers. Obviously the front goes on no problem. For the back, I chose to use a small bottle jack. I placed it on top of the SuperSpring and extended the jack so it pushed up on the bottom of the bed of the truck. This easily and quickly compressed the spring.
Unloaded ride height was unchanged. I'm hoping to test it pulling our travel trailer in the next couple of days and will update on how it works under load.
Their website makes it easy to find the right Superspring for your truck. They install easily and work great. The only thing that was a surprise is that I had to use a 6" c-clamp to compress the spring enough to get the rollers on. No big deal, but nothing was mentioned about a spring compressor on the "tools needed" list.
The supersprings are simple to install. Good instructions. They have done a great job on helping with weight. The Poly Spring Pads do not last. I have had this setup for 7 months and the pads are falling apart.
After listening to my new trucks squeaky suspension for almost a year and installing air bags that were useless, I tried these springs and these are the best investment I’ve made for my work truck.
No more squatting and the best part no more squeaking!
Love the super springs. They keep my truck from sagging which gives me complete vehicle control. Would recommend for someone that tows often.
Took the squat out of the F250 when pulling our fifth wheel.
Great product !
work's Great , I will be purchasing mor e.
Item is in great condition but the shipping box was completely torn up
Installing these on a 2020 F250 was easier than I thought it would be. I was able to get the springs on whit the center piece and the front shackle bolted without jacking up the truck. I had to jack the frame up a few inches on each side to get the back shackle bolt through. I put the shackle bolts through the bottom holes since I only need the extra support when I tow. I recommend air / power tools for the shackle nuts and it doesn’t hurt using them for the center bracket u bolts. They are lock nuts and they have a long way to run on for each bolt. I did have to bend my parking brake cable hangar out a bit for one of the shackle bolts to clear the cable. The truck seems to sit a little higher in the back. Maybe an inch or so. The ride empty seemed the same except it felt like it didn’t roll quite as much when turning. Rolling over a lip at the end of our driveway the extra stiffness was noticeable, however. I won’t know how well they really work until I get my fifth wheel hooked up.
The Super Springs work great! I pull a 8,500# trailer with a hitch weight of 950# with a 2004 GMC Sierra 1/2 Ton. The truck pulls fine but even with an equalizer hitch still had some sag. The Super Springs were easy to install and leveled the rig. After a year everything still works great.
No issues with install on a 2023, E350 Class C motorhome.
After chalking the front wheels, I used two 3 ton floor jacks with 13” 6x6 blocks just behind the springs to lift the frame and rear tires off the ground to remove the wheels. For safety, 3 ton jack stands were put under the axles during spring installation
After installing the springs per manufacturer instructions, two 1/2” x 10” pieces of all thread with drilled flat bar were used to compress the front end spring.
With the least amount of preload it raised the back a good inch.
The 800# trailer tongue weight will be the next test to see if more preload is needed for a level ride height.
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.
Installed on a 2016 Toyota Tundra. I pull a 28 foot aluminum frame utility trailer. Hauls like a 3/4 ton with super spring. Rides like 1/2 ton without load. I have put 1 ton load on truck with no trailer and the truck drove fine. The front of truck at tires rose 1/2 inch. Installation requires the frame to be lifted off the axel.at rear of vehicle. I like this system better than air shocks as there is no adjustment after installation. I would purchase again.
I got this to prevent bottoming out my truck when towing our travel trailer. Won't know for sure if this actually works until we load up. Having said that, the instructions provided with this are poor and talking with Supersprings tech support was frustrating. As mentioned elsewhere, you will need two "C" clamps to pre-load the spring and I wound up fabricating a 3" extension bracket for the brake lines; neither of which were mentioned in the instructions. I also removed the wheels to provide working space and air tools are definitely the way to go. On my '13 Tundra, the distance between the stock spring pack straps is 40" the same as the distance between the eyes on the Superspring. I was advised that the spring is mounted off-center to avoid conflict with the stock spring straps; however this in not mentioned in the instructions. This placed the Superspring about 4" forward of the center of the axel instead of centered on the axel. (see photos) This seems counterintuitive to me but we'll see. This added 1.5" in height to the rear of the truck. It took me 4 hours to install by my self, including time to fabricate the brake line extensions and dealing with Supersprings staff twice on the phone. During the second call, the tech mentioned that they get a lot of phone calls for Tundra installs, indicating to me that they already know there are issues with the product and instructions. In retrospect, I would look for a new spring pack if I was doing this again. Hopefully my suspicions are unfounded but I'm hanging on to the box just incase. Etrailer was great with the best price anywhere and quick shipping.

Installed it about a year ago. The springs are working out great. I don’t have the sagging of the rear end like I use to when towing. I have had to replace the pads once, but besides that, it’s a awesome system.
