The NHRA, Nascar and other professional racing series are now mandating the upgraded SFI 16.5 certification on seat belts, shoulder harnesses and crotch strap(s). The seat belts manufactured by Crow Safety Gear have recently passed the testing and obtained the SFI 16.5 tags. Consult your rule book to verify if these type of belts are necessary for your division of racing. Also, confirm the crotch strap or anti-submarine belt requirements. You can select the option for a 5 Point, 6 Point or 7 Point assembly.
