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.

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 semitruck 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.

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.


This T1N 2001-2006 Sprinter Vans suspension stabilizer kit is perfect for trucks towing fifth wheels, campers and gooseneck trailers.

An additional mounting kit is included for installation with factory springs that set above the axle.


For T1N 2001-2006 Sprinter Van’s with factory leaf springs that set above the axle, this mounting kit ensures that SuperSprings operate silently when the vehicle isn’t loaded. When factory springs set below the axle, the axle itself serves as a fulcrum for the helper leaf springs. However, for vehicles that have OEM springs that set above the axle, the 2-inch brackets in the mounting kit act as fulcrum points on the underside of the SuperSprings. Furthermore, the shackles at the ends of the helper springs hold them 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.
