Simpson Custom Hybrid S FHR Device

The Hybrid S from Simpson features a lightweight design using DuPont carbon/polymer construction and provides maximum comfort and maneuverability with superior strength. Simpson Hybrids come race-ready. The trusted low profile design disappears into the seat when worn and allows for easy in and out of the race car, eliminating the danger of becoming caught in other gear. The protection stays with the racer during multiple impacts, flips and rolls.

Simpson Hybrid S Head and Neck Restraint 

Advanced Protection for 3-Point and Multi-Point Harness Systems

The Simpson's Hybrid S model 3-Point Head and Neck Restraint is the only head restraint on the market proven to offer protection with both three-point OEM seat belts and multi-point racing harnesses. It was specifically designed and tested for use with OEM three-point seat belts.

This innovative head and neck restraint device also meets FMVSS testing standards for compatibility with 3-point belt setups—making it the ideal solution for high-performance driving instructors, automotive test engineers, and track day enthusiasts who want next-level safety without needing to retrofit a full race cockpit.

FIA and SFI approval require the use of a five-, six-, or seven-point racing harness system.

Designed for superior protection in street cars and club racing vehicles, the Simpson's Hybrid S model features a low-profile, high-strength carbon fiber construction that won’t interfere with roll bars during emergency exits. Multiple load paths help dissipate energy in a crash, while the front-mounted buckle system eliminates bulky straps underneath, providing all-day comfort. Whether you're in a fully prepped race car or a manufacturer test mule, the Simpson's Hybrid S model bridges the gap between OEM safety systems and motorsport-grade head restraint.
