The HANS device stands for Head and Neck Support. It was designed with you and your family in mind. The goal in racing is to go faster than anyone else on the track and cross the finish line first. And as technology increases speeds, it also increases the risks. Remember, you a have a family to go home to when the night of racing is over.

The primary difference between the Pro Series and the Sport Series is the weight. There is no difference in the safety protection offered with either one. The Pro Series weighs approx 1 lb. less than the Sport. We offer both models with quick disconnect sliding tethers. This gives you the most mobility and vision. You will need a 1/4" drill bit and a measuring tape to install the HANS device anchors to your helmet. Complete instructions and a special tool are included.

Made with high modulous carbon fiber this is the ultimate in lightweight protection.  Includes quick disconnect and sliding tethers.
