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.

SuperSprings were a great addition to our van. Sway control improved immediately with the SuperSprings. The process to install SuperSprings was moderately challenging but my son and I got them installed at home. Purchasing a set of C-clamps made it possible. Definately worth their price!



by:

Excellent customer service and quick delivery. Will definitely use them again



by:

I think they perform exactly as advertised. I will admit, they took some patience and strength to install. I believe it was more hours then the estimate that was shown, but that's because I don't have the install compression tool and had to make my own... Otherwise, it performs perfectly, you can feel the difference immediately, price is good and quality is there. Quality is something that is lacking in many products in todays world, but not on this one. Thanks!

Great product and fit. A bit difficult for two 73 year old men to install, but it’s done.

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:

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:

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:

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:

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:

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:

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:

i have these on a couple of trucks and they work great.more reliable than air bags



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:

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:

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



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:

Pretty sweet. Immediate and noticeable improvement for my sprinter conversion. Disappointed I waited so long to install.



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:

I am 100% pleased with etrailer...received wrong suspension because of manufacturer's misrepresentation...Tiffany at etrailer corrected everything...sent a prepaid UPS label to send it back...sold me the proper stabilizer springs...and gave me 100% credit back on the wrong purchase...these people are true to their word and I recommended them to everyone...P.S. today I installed the new stabilizers and they work like a charm...and...I talked to Tiffany on Monday the 9th...received the new stabilizers on Wednesday the 11th and installed them on Thursday the 12th...10 thumbs up to Tiffany and etrailer...thanks,



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:

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:

I bought this item for my 20 year old 37' motor home. Over the years the rear end has "squatted" down some and due to the weight of the frig, washing machine, and a small freezer all being on the passenger side, it was lower on that side. Installation was not the easiest thing, but this 70 year old was able to do it by myself, even on a gravel driveway. Installation instructions are good. Besides the drive axle, my rig has a second, "drag" axle, whose tires I had to remove to do the job. I also had to re-route a propane line. The hardest part was Step 7: "Using a heavy duty C-Clamp or SuperSprings installation tool, pull down rear of SuperSpring and install bolt,..." I used 2 C-Clamps and it was pretty tricky. I'm not sure what the price of their special tool is and I don't think etrailer sells it. I used the bolt hole that gave me the maximum lift on the passenger side and the first hole on the driver's side. The completed installation did accomplish my goal of leveling the motor home. These springs are really heavy-duty and very good quality. I have no complaints.

    When installing the SuperSprings Custom Suspension Stabilizer part # SSA43 on your 2017 Ford Transit T350, if you have two leaves in your leaf spring stack then you can use the middle bolt hole on the shackles but if you have three leaves in your leaf spring stack then you will need to use the lowermost bolt hole.

  • Will SuperSprings Suspension Stabilizer Lift Rear of 2018 Winnebago Fuse 23T
    The SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA43 that you referenced will do a really great job of stiffening up the rear suspension on your Winnebago so that it better handles any loaded weight but it's not going to actually provide the 2 inch lift you're looking for. It could potentially lift it just a tad if there is indeed some rear sag on the chassis due to the added weight of the RV and gear but only because you are installing additional support with the...

  • What Size C-Clamp Should be Used to Install SuperSprings # SSA43
    There isn't a specific size C-clamp listed when installing SuperSprings # SSA43 but something that has about at least a 4 inch gap between the upper and lower ends of the clamp, when fully opened, would be sufficient. Basically it is used to bend the spring a little at the rear to be able to finish the installation.

  • Recommended SuperSprings Suspension Enhancement for 2017 Ford Transit 350HD
    SuperSprings explains their weight ratings in the following way: "If you were to take the ends of the SuperSprings, apply pressure down, and turn the arch into a straight line, this is how we rate their capacity." They also have three different settings, including a "medium" that will offer the support you are looking for in your 2017 Ford Transit T350HD but without creating a harsh ride. Due to this I recommend the SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA43,...
