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:

  • Reinforce your vehicle's rear suspension with extra leaf springs that prevent sagging and reduce sway by up to 30 percent
    • Work like sway bars to stabilize your OEM springs and keep them from twisting

    • Lift your truck when you are carrying a heavy load and prevent bottoming out
  • Adjust automatically to your payload
    • Rollers on each end of the SuperSprings activate when the OEM springs flex under load
    • Rollers deactivate when OEM springs aren't under load
  • Can be customized - the shackles attaching the SuperSprings provide several options for installation
    • Choose a setting that increases load support and ride height for constant heavy loads or to compensate for minor spring fatigue in an older automobile
    • Choose a setting that maintains the original factory ride conditions and minimizes effect on unloaded ride quality and height
    • Choose a medium setting that balances support, height, and ride comfort
  • Install easily - bolt on above your existing factory springs with no drilling required
    • For some models with factory springs that sit above the axle, the included poly spring pads prevent shifting
    • Dense polyurethane blocks seat between the top of the factory springs and the underside of the SuperSprings
  • Require no maintenance - no tubing or air pressure to monitor or adjust like air springs
  • Extend the life of brakes, tires, and factory suspension

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.

2001 Ford F-250 Super Duty

I bought this product for my 2001 F250 that I use to haul a 24' gooseneck horse trailer typically loaded with about 3000-4000 lbs of cargo.
My truck was squatting and I was experiencing sway, expecially on the interstate when passing tractor trailers.
The super springs greatly improved my truck's suspension and performance when hauling. I would highly recommend this product.

1999 Ford F-250 and F-350 Super Duty



by:

I used the SuperSprings to help support my Slide In Camper for my 2500 Chevy. They support good. I have Timbren installed also, but were bottomed out. After adding the SuperSprings with the Timbren the camper is supported good. The truck sits and rides level



by:

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.



by:

They increase the carrying capacity of the stock springs by adding an additional leaf. We drive our van with most of the load above the rear suspension and it was bottoming out on occasion. Works as advertised; no more bottoming out! It is a bit of a struggle to install, so a professional may be needed



by:

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.



by:

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.



by:

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.



by:

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!



by:

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.



by:

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.



by:

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).



by:

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.



by:

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.



by:

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.



by:

These worked great crossing the country last month.



by:

Great product, fast shipping. My only complaint is the package was delivered with both ends of the box ripped open. Luckily no missing components



by:

Looks like good product.
Haven't installed
them yet but looks like good quality.



by:

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.



by:

The install was pretty straightforward and so far they are doing exactly as they should. The packaging was less than desirable though. The box arrived, opened on one end and the springs hanging out of it. Both plastic bags with the smaller parts were ripped open as well. One nut was missing but fortunately I was able to match it up with what I had on hand.



by:

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.



by:

Overall, the installation of the SuperSprings kit went pretty well. The instructions sent with the kit were not all that clear, but the info on etrailer's website saved the day. Can't wait to put the camper back on the truck and see how it rides!



by:

A no-brainer. Worked perfect. I recommend this for any problems.

It is often a smaller spring, yes, and it is not necessarily bound to the other springs.
