    SFI-approved B&M Flexplates are NHRA/IHRA legal for all classes of Chevrolet and Chrysler vehicles. A SFI certification sticker (with re-certification required every 3 years) is included with each SFI-approved flexplate. B&M non-SFI Ford flexplates are made exclusively for small block engines and do not meet SFI certification standards. These B&M flexplates are designed for street use, extreme duty racing and high (above 6,000) RPM applications.
