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.

Product does just what it says it does. Installed them on a Thursday and towed with them that weekend....... and they did a great job. Handled the tongue weight of my dump trailer better. I did notice a decreased amount of "wave" effect when you are in tow and your heavy trailer hits a bump or swale in the road; and transfers that energy to the truck. Sorta feels like you got a heavy tail that someone is tugging on. This was significantly reduced and made for a pleasant ride Later on Sunday then threw a load of firewood (no trailer this time) in the bed full; and in comparison of a previous haul with wood the truck did not sag as much. My truck config is stock, double cab w/ 8' bed 4x4. I did not notice a stiffness in ride with and empty bed or no trailer in tow. Seemed to be just fine. Slightly raised the rear but with the long truck it is hardly noticeable. One part of the installation was a little difficult, when it came time to compress the leaf it was a bit of a chore. I did have a 5" c-clamp but it was getting tough the last few inches to get the roller underneath the stock leafs. If I had a special leaf spring clamp tool as shown on some of the youtube vids I would have been done in about a 1/2 hour but with out this tool it makes the compression part slow. 145702

Great item!! The Supersprings performed just as described. No more sag in the suspension and the benefit of better control. Installation was an hour with the help of an experienced mechanic and the right tools. If it wasn't for removing of the bumb stops on the axle, installation would have been faster. Expensive product, but it is a quality product and made in the USA. After install, the springs raised the rear of the truck about 2" to 3" when unloaded. Best part is that the springs didn't cause the truck to ride rough when unloaded. 21988

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. 865324

2013 Toyota Tundra

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. 108092

2013 Toyota Tundra 4x4. Installation went well in my garage with a medium sized C-Clamp. The ride feels that same as stock. Lifted the rear 1.5" which helped off set the 2.5" lift in the front from Fox 2.0 shocks. I have not hauled a load yet. 107263

These Supersprings are great! I carry my snowmobile in the back of my 2007 Tundra. The trucks ride is noticeably more firm without the bottoming- out that I had been experiencing. Pretty easy to install. Probably took me 6 hours maybe a little less. The worst part was getting my rear tires removed. The directions said this was not necessary but I highly recommend taking them off. Great product so far! ***** 5-Star rating from me! Ray Z. 33142

Review from a similar Sway-Control in Vehicle Suspension


Just installed and I loved how easy it was took 30 min tops. I expected a much stiffer rear end with the bed empty but was pleasantly surprised at how smooth the ride remained. I did notice a more stable and responsive feel while driving. All in all super impressed with the product so far, shipping was fast (ordered Saturday and received Wednesday, in canada) everything I needed was in the kit and it only raised the rear end up about 1/2". 316290

It a good product for 2017 Ford f150 except 1 factor that it had to mounted more toward the rear and the no bracket to hold it in place if I get a tire rotation or lift the vehicle from the rear the spring roll away and need to clamped while lowering the vehicle. I contacted Super directly to there warranty department and they sent me a lock down kit. It also Lifted the truck about a inch on low setting so I'm sitting at 39 inch in rear. 505177

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. 603418

If you look at page 4 of the instructions which Ive linked for you, you can see photos showing a single leaf spring set up just like whats shown in the photos you provided thanks for the photos!. Im guessing that page was not included in your instructions for some reason.

Review from a similar Sway-Control in Vehicle Suspension


After having used partial and full ‘add-a-leaf’ kits on fleet trucks in the past, I was willing to give these a try. Having missed the stiffness of a 2500 rear end and having put 125k on a 1500 with a topper/camper shell, this was the progressive stiffness I was looking for. The vehicle sits 1.5” higher at the rear, isn’t overly stiff, alowing the Bilstein shocks to continue to do their job, properly. Adding the tow behind camper, along with a loaded bed, far less body sway without a compromised ride. I also utilized the SumoShocks (front and rear), for some time and I love them. Having everything together, as a package, works great for me when towing, the bed is loaded down and when I’m traveling 2hrs at a time from place to place, as a highway truck. This will take some serious C clamps (8” from hardware store) and some mechanical aptitude if using a jack and stand(s) in the garage. Overall, not too strenuous or hard. Nothing intimidating. I’d definitely recomend to anyone wanting to help tired leaf springs or when reducing body roll. 557350


Comments
The Sumo Springs continue to provide wonderful results. Many friends with 2500 trucks and onlookers at campgrounds are amazed when we tow our 38’ trailer weighing around 8k lbs when loaded, plus the truck bed loaded with wood and bikes, etc, the family and dog in the cab... All with little to no squat! The ride stays consistent to the 2500 feel I like and it allows me to keep my ol’ beater with high miles and a few thousand miles. I definitely recommend the Sumo Springs and their products. Again, having had their products on other vehicles with more than happy results, I don’t foresee ever purchasing a vehicle and not, at the least, including the rear bump stop supports and adding the leaf kit from there.

I received the kit two days earlier than expected; which, in itself was very reasonable (7 days). I received the springs on Monday and installed them on Tuesdays. The lift is unquestionably and under load quite obvious! In the coming days I will naturally be testing it for performance, but for now I'm very pleased!!! 864556

    The SuperSprings Leaf Springs, # SSA4, will not interfere with the brake line on your 2008 Toyota Tundra if they are installed properly. SuperSprings makes a special note in their installation instructions regarding the brake line. To avoid interference, you will want to bend the brake cable bracket at the leaf springs slightly forward. I have attached the image from the instructions for you to check out. I have also attached a link to the installation instructions.

  • Troubleshooting Squishy Ride Quality with an Air Suspension System and Weight Distritbution System
    I believe the ride quality issue you are experiencing is related to the fact that you are using an air spring system with a weight distribution system. If you have a properly rated WD system and it is set up properly you should not need to use your air springs to level the truck. It should be leveled already from the WD system. I would double check that your WD system is rated for the loaded tongue weight of your setup and that the WD is set up properly. I attached an FAQ on determining...
