HANS IV 20 Medium Quick Clip SFI

The HANS IV 20 Medium Quick Clip SFI is a professional-grade head and neck support system designed for drivers competing in high-speed motorsports environments. Built to meet SFI 38.1 and FIA safety standards, this device protects against lateral and rotational neck injuries during aggressive cornering, acceleration, and crash events. Engineered for medium frame drivers, the HANS IV 20 combines proven restraint technology with quick-engagement tether mechanics, making it the trusted choice for road racing, circuit competition, and professional motorsport applications where safety certification is non-negotiable.

The HANS IV 20 utilizes a dual-tether quick-clip design that anchors securely to your racing harness while maintaining the low-profile, lightweight construction motorsports drivers demand. The plastic composite shell distributes impact forces across a wider surface area, reducing concentrated stress on the neck and shoulders during extreme G-forces. Quick-click attachment points allow for rapid donning and removal without sacrificing structural integrity or safety margins. The medium sizing is calibrated for drivers in the 160–190 lb range, ensuring proper contact distribution and optimal restraint geometry for maximum effectiveness.

Professional racers, amateur circuit competitors, and serious driving enthusiasts benefit most from the HANS IV 20's SFI certification and FIA approval—essential credentials for sanctioned events and racing series worldwide. Installation integrates directly with most racing harnesses through the quick-clip tether system, requiring no modifications to your existing safety equipment. The medium configuration delivers the balance of support and comfort needed for multi-hour endurance events while maintaining the rigid, tested protection that separates certified safety gear from aftermarket alternatives. Whether preparing for your first track day or competing at regional or national levels, this head and neck support device delivers measurable injury risk reduction backed by racing safety standards.
