SFI Approves New Bellhousing Specification with Five-Year Certification

Columbus, Ohio—NTPA Technical Services has successfully petitioned the SFI Foundation to add a bellhousing certification that specifically addresses truck and tractor pulling applications and extends certification period to five years for steel and titanium bell housings. This new certification was approved by SFI on July 24, 2023.

SFI Specification 6.4, “Puller and Diesel Drag Racing Bellhousing,” was jointly pursued by the NTPA and National Hot Rod Association, which joined the effort initiated by the NTPA in January 2021. The SFI 6.4 specification contains a five-year certification period for steel or titanium bell housings specifically used in pulling and drag racing competition. A two-year certification limit still exists for aluminum bellhousings and remain as SFI 6.3 certification only.

Existing SFI 6.3 certified steel and titanium bellhousings automatically meet SFI 6.4 requirements in an automotive application since there is no change in the construction of the bellhousing required. Such certification can be applied by the manufacturer with no additional testing required. Competitors are encouraged to request their bellhousing manufacturer to apply the new SFI 6.4 certification decal and 5-year certification period to their steel or titanium bellhousing.
