LET’S TOW SOMETHING
Super Springs International. Sumosprings were developed to enhance the load-carrying ability and help stabilize heavy loads for better driver control and ride quality while offering maintenance-free use for the lifetime of the truck. With traditional airbag kits it’s not uncommon for small air leaks to develop in lines or the bags themselves. Over time, an on-board electrical air compressor could need replaced after excessive moisture or use burns it up.
Using a unique micro-cellular urethane, the Sumosprings act much like a large bump stop with a progressive spring rate that helps handle the additional weight and dampen the ride for better stability while driving. The biggest difference between Sumosprings and airbags is how the air is captured and used within the bag. A standard airbag is much like a balloon, trapping air within it, where the air pressure used controls the spring rate. The Sumospring captures millions of small air pockets within its urethane material. They can’t leak and can be compressed to 80% of their original height and still rebound to factory form.
We determined the two-piece Rebel kit in the mid-density would be best for this daily driver and weekend tow rig. Super Springs offers three different Sumospring variations, each having three different densities to fine-tune the load support based on the weight you’re pulling and how often you pull it. The Rebel kit works great on a daily driver since when unloaded the travel won’t be limited because the axle is still working independently from the frame. Because the upper and lower pieces don’t require air pressure and don’t ride on each other, unloaded ride quality is unchanged. But as the weight from a trailer is added the two pieces will meet each other and start to compress, offering better support and helping to dampen the ride more effectively than the factory leaf springs and shocks could on their own.
