When the bed or trailer load starts to weigh down the rear, these helper leaf springs add up to 1,300 lbs of extra support. They mount above your factory leaf springs to keep your truck level and eliminate sag so steering, braking, and handling stay consistent. With less squat under load, you get a steadier ride and proper headlight aim even when the truck is packed or towing heavy.
Strong crosswinds, highway turbulence, or cornering weight shifts can make any truck feel unsettled. These helper springs act like sway bars by stabilizing your factory springs and keeping them from twisting. The result is up to 30 percent less sway and a more planted feel when wind or uneven roads try to push you around. Your ride stays more controlled through turns or when a big rig blasts by.
There’s nothing to inflate or monitor. Rollers on each end of the SuperSprings automatically engage when the factory springs flex under load and back off when unloaded. That means the springs only work when you need them—lifting your truck under heavy load while keeping normal ride quality when empty. It’s a simple mechanical design that delivers real support without maintenance or air pressure checks.
The shackles give you several setup choices so you can dial in how much support and ride height you want. Use the upper bolt holes for constant heavy loads or older suspensions showing fatigue, the lower holes to keep a near-factory ride height, or one of each end for a balanced mix of comfort and lift. Once bolted on above your factory springs—no drilling required—you’ve got a customizable solution that responds automatically to whatever you haul.
Dense polyurethane pads keep the springs seated and prevent shifting, while the tough steel design needs no upkeep. With no air lines, compressors, or fittings to worry about, these helper leaf springs just keep doing their job—reducing wear on brakes, tires, and suspension components so everything lasts longer under real hauling conditions.

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.
