    The NecksGen NG800M/L REV X Carbon is a high-performance head and neck restraint built for motorsport safety, combining a hollow-core carbon-fiber chassis with an adjustable X-strap harness for a secure, custom fit. Designed to reduce neck loads under impact, even when used with a standard 3-point belt; it delivers lightweight comfort and enhanced protection for racers on track or street-legal performance builds. Quick-release helmet hardware is included for added convenience and fast helmet removal in emergency conditions. The system is SFI 38.1 certified and available in multiple adult sizes for broad compatibility.

    NecksGen NG800M/L REV X Carbon Head & Neck Restraint Features:

    • SFI 38.1 certified carbon-fiber frame for reliable impact protection
    • 1.8 lb total weight including harness; reduces fatigue and improves driver comfort
    • Adjustable X-strap harness accommodates 2 in. or 3 in. belts and different body sizes
    • Quick-release helmet hardware included for fast exit/entry
    • Compact design minimizes interference with seats, helmets, and tight cockpits
    • Reduces neck load during frontal impacts even when used with a 3-point seatbelt (though 5- or 6-point harness is still recommended for racing)

    NecksGen NG800M/L REV X Carbon Head & Neck Restraint Notes:

    • Sold as harness/neck-restraint only; helmet and seatbelt harness not included
    • For optimal safety, use with high-quality racing harness (5- or 6-point) when possible
    • Must be recertified every 5 years per SFI requirements and tether should be inspected/replaced after any impact or every 2 years per manufacturer guidance
    • Adjust tether slack (typically 1–2 in.) per manufacturer instructions to ensure proper range of motion and engagement on impact
