Quote: This is a direct copy from an e mail question I asked SFI. IMO if the material is only good for two years USE A BETTER MATERIAL!
"The life of the harness certification is due to the known properties of webbing and the relatively rapid degradation over time. There have been many studies, including those by the U.S. Army, the NTSB, Industry associations, and SFI. Some of these studies are summarized in the attached document."
Perhaps they should use the same thread as the factory belts (Ford, Chrysler, GM) as they don't see to degrade in 2 years.
