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.
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:

thanks guys will be ordering from ya again
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!!!
The staff at etrailer really did a good job on my order , they made sure that it’s the right part and keep me updated on the status of delivery.
Easy install, I’m 71 years old, it took me 140 minutes to do the installation.
I haven’t towed with them yet but the truck ( 2012 GMC 1500) rides and handles much better.
These are very pricey but so far so good!
After installing these products on my 2006 Dodge Sprinter the van rides a lot smoother and with very much reduced sway.
This leaf springs kit help greatly. It helps stabilized the van and gives it a much better ride. I would highly recommend this kit.
looking for something that would allow me to haul/pull a little more weight, this is it. was easier to install than I thought it would be. could tell the difference right away. have a smaller travel trailer, this took almost all the sag away.
These "helper" springs made the difference between towing with our E150 Ford conversion van or buy a different vehicle. Our tow vehicle rides a little stiffer, but that was expected. It certainly gives us the confidence of towing a 26' camper.
Super Springs and mounting kit was very easy to install on my 2002 Chevy Silverado 1500 4x4. The springs raised the ride height 1-1/2 inches and made a big improvement to the original leaf springs that were sagging. The truck drive like new again with less body lean in turns. The ride quality actually improved
