Did you know that the acceleration forces in today's race cars are only exceeded by those in fighter jets? Now you know why so many racing teams trust harness restraints from SCHROTH. Maximum safety all the way to the checkered flag.


The SHR FLEX is the latest in FHR [Frontal Head Restraint] technology. Designed and developed by the team at SCHROTH, the SHR FLEX provides enhanced comfort, uniquely adapts naturally to different body types and seating positions, and is simple to use versus existing systems on the market.

The new SHR FLEX is a dynamic Frontal Head and Neck Protection [FHR] system with many technological advances.  Design highlights include patent pending dynamic articulation of the collar, a rate responsive bump stop to manage peak neck tension loads as well as a stabilizing dual tether system and FLEXible form fitting lower legs to provide optimal fit and reduce interference with the seat.

The SHR FLEX has been designed with a low collar to be angle independent of your seating position. Pliable legs with a low-profile integrated padding system form-fit to your upper body and chest, providing class-leading stability and allows the belts to ride close to the body for enhanced harness performance. Eliminating the external padding systems used by other FHR systems means the SHR FLEX feels planted. There’s no disconcerting floating around feeling that something’s loose.  And, it means that all it takes to cleaning the SHR FLEX is a simple rinse with warm water and wipe down.

In addition to advanced comfort design of the SHR FLEX the new device has been optimized with winglets on the upper collar and SCHROTH's patented SlipStop system on the lower legs to assist in belt retention for off-road and rally sport competitors, and during secondary impacts.

The SHR FLEX has been designed and tested for use with standard 3" racing belts as well as FHR specific 2" shoulder belts.

This product has undergone and passed SFI 38.1 which is a test standard evaluating the effectiveness of a Head and Neck Restraint [FHR] device. It utilizes a dummy seated in a frontal test sled accelerated at 68 G in order to generate high neck forces such as which may be found during an actual severe frontal crash. Neck tension/compression and the Neck Injury Criterion [Nij] are measured and evaluated against pre-determined injury threshold values. Two direct frontal [0deg] impacts and one side [30deg] impact are required for certification.

SCHROTH Racing’s SHR FLEX frontal head restraint safety system for racecar drivers has won the 2016 elite Plus X Award for its Innovation, High Quality and Functionality
