The S3 Synchro Stinger Trailer is the best solution to an increased payload. It equalizes the load on a heavy equipment trailer and distributes the weight on the axles equally. S3 has other product offerings such as the hydraulic Synchro Spreader Bar and Pin-On Axles that work in conjunction with the Stinger technology for a cost-effective system. Our new, innovative automation software allows Stinger Trailers to be controlled by a tablet or an app on a cell phone from the interior of the cab. After initial verifications, "auto mode" will balance airbags while driving down the road, adjusting the pressure difference between the truck and the Stinger. Backup mode allows the Stinger to be raised for backing into a parking spot from the cab. Our equipment is made in the USA! Manufacturing takes place in our world-class facility located in Wallace, Michigan (www.adv-blend.com). Using state of the art equipment, each trailer is welded with T-1 steel and assembled with proven to the market axles and suspension. S3 has high standards in quality control and will stand up to the Superior name.
