HANS III Model 30 Large PA Sliding Tether

The HANS III Model 30 Large PA Sliding Tether is a head and neck support system designed for motorsports, aviation, and high-performance driving environments where occupants face sustained lateral acceleration forces. This device protects the cervical spine and neck muscles during cornering, braking, and collision events by laterally constraining head movement and distributing inertial loads across the shoulders and torso. The large sizing accommodates drivers with broader shoulder geometry or those wearing thicker racing suits, while the sliding tether mechanism allows natural forward and backward head motion during normal operation.

This model features SFI 38.1 certification, the sanctioning body standard for head and neck restraint devices in motorsports competition. The construction employs plastic composite materials for the collar structure, reducing weight while maintaining rigid lateral support geometry. The sliding post tether design permits longitudinal flexibility—essential for natural breathing and visibility—while the post-to-harness attachment system transfers lateral forces through a wider load path than fixed designs. At 2.87 lbs, the HANS III remains lightweight enough for extended wear without fatigue, critical for endurance racing or long-duration flight operations.

Professional drivers in open-wheel racing, sports car competition, and high-performance road courses benefit most from this configuration. Installation pairs with a multi-point racing harness; the tether attaches to shoulder harness straps at approximately shoulder height, creating the biomechanical advantage of load distribution across the clavicle and upper back. The large sizing fits drivers with neck circumferences and shoulder widths in the upper range, making it ideal for heavyweight competitors or those requiring additional padding beneath racing suits. Verify harness compatibility and installation per SFI guidelines before track use.
