Now offered in 3 different sizes, at a lower price, the Hans IV is a new and improved FHR (Frontal Head Restraint) that is 10% lighter than the previous Hans III. Custom molded pads which nest into the device, preventing slippage, were designed with an upgraded foam for improved comfort and support. Offered a 20 -degree option, this FHR is perfect for the entry level driver across many race series.
