3,000-lb Capacity. Upgrade your 's rear leaf spring suspension with these helper springs. They reduce sway and prevent sagging, which is perfect for towing or hauling heavy loads. Designed for factory springs that sit above the axle.
Features:
Specs:
An additional mounting kit is included for installation on suspensions with leaf springs that sit above the axle. This mounting kit ensures that the SuperSprings operate silently when your vehicle isn't loaded. The brackets in the mounting kit act as fulcrum points on the underside of the SuperSprings. Furthermore, the shackles at the ends of the SuperSprings hold the spring in place and pivot as the load is transferred to the SuperSprings. Because there is minimal preload tension in the installed SuperSprings, you get a quieter ride.
These additional leaf springs add support and sway control to your existing factory suspension. Just bolt on SuperSprings over your factory springs, and they automatically work when you need them. As the factory spring flexes, a roller at each end of the sturdy 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 factory 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 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.
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.
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 different installation options:

3,000-lb Capacity. Upgrade your vehicle's rear leaf spring suspension with these helper springs. They reduce sway and prevent sagging, which is perfect for towing or hauling heavy loads. Designed for factory springs that sit above the axle.Added these springs to my 2500 Silverado to prepare for a slide in camper. They made quite a difference. I did it myself, but two people would be easier. The ride is naturally a little stiffer when empty, but that's the trade off.
Great product, very clear instructions. I really appreciated the stickers on each spring showing the correct orientation, that took all of the guess work out of it.
Thanks Supersprings for making a great kit and confirming the product would work with the airbags I had installed.
Packages arrived on time, everything was there, installation went good, I removed the rear tires to make it easier, picked the rear of the truck up by 1 3/4 inches, have not hooked up 5 th wheel yet, we will see if it helps with the bottoming out .
This was installed on a Chevy 1 ton with camper works great for helping sway
and suspension
Awesome! easy to install
Makes big difference when towing 6000lb loads
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.
This was by far the easiest mod I have made to my 2019 Ford Super Duty King Ranch! Only took 45 minutes start to finish. Didn't even take the wheels off. Took some pressure off of the springs by lifting the rear end a little using the trailer hitch. Used the bottom holes on both ends and only raised the rear of the body 1 inch. Great product!
i have these on a couple of trucks and they work great.more reliable than air bags
Product worked as described. Shipping was quick (etrailer used "air" to my state, then on UPS truck)
Easy to install, not sure why they included 2 sets of polyurethane blocks (only one set fit my truck)
Don't notice any ride difference when set at lowest setting. Raised truck approximately 3/4". East to readjust for more preload if needed.
Combined these Super Springs with Timbren load handlers. So far so good.
Great improvement over stock while maintaining ride quality.
This helped immensely with the wondering in the steering of my e350. The shop that I had install it has been recommending this to their customers
E-trailer agent James helped find trailer tow package that fit my 2011 Ford Transit Connect and provided appropriate install video. You're a huge help James. The install went smoothly without a hitch (lol).
Pretty sweet. Immediate and noticeable improvement for my sprinter conversion. Disappointed I waited so long to install.

They work great, they improved the rear suspension so there is no more bottoming out when I pull the 5 wheel Rv .
