When your truck squats under a heavy trailer or bed load, these helper leaf springs step in with up to 1,100 lbs of load support. Mounted above the factory springs, they automatically engage as weight increases, lifting the rear to prevent bottoming out and keeping the truck level. That means a steady stance for safer braking, steering, and headlight alignment when towing or hauling.
Strong crosswinds, passing semis, or sharp turns can make a loaded truck feel loose. These helper springs act like sway bars by keeping your factory springs from twisting. The result is up to 30 percent less sway and a more planted feel when cornering, battling wind turbulence, or driving on uneven roads.
No need to crawl under the truck or monitor air pressure. Rollers on each end of the SuperSprings automatically activate when the factory springs flex under load and back off when the load is gone. The system adjusts itself every time you drive, so you get support when you need it and near-factory ride quality when unloaded—with no maintenance required.
The shackles that attach these helper springs offer multiple mounting options so you can tailor the setup to your needs. Use upper bolt holes for greater load support or to compensate for older spring fatigue. Choose lower holes to maintain the original ride height, or mix settings for balanced comfort and lift. It’s an easy way to fine-tune handling whether your truck carries constant weight or runs light most days.
The kit bolts directly above your existing leaf springs using included hardware—no drilling needed. For models with factory springs above the axle, dense polyurethane pads keep everything seated and prevent shifting. With just hand tools and clear diagrams, these helper springs can be installed in an afternoon by any DIYer ready to add reliable suspension reinforcement without complicated air systems.

That is great to hear! I am glad this addition has worked well for your setup. What RV do you have that you added this too?

The product works great after a year. I highly recommend the super springs for any heavy loads. After they are installed you never need to worry about the load.

Thanks for your feedback, Bob! We’re glad to hear the shackles made a noticeable improvement in your ride quality. We appreciate you pointing out the fitment challenge and the issue with the instructions, I'll pass it on to SuperSprings.

They are working out fantastically! Now we dont bottom out and damage the sewer dump. Weve been all a long road trips and nothing is bothering us now in regards to suspension.

Works great towing and seems to help with some sag and roll. I use them along with airbags so towing my fifth wheel is now worry free.
