Arizona Warrior:
I tracked this down with a search based on posts by members and by going back thru popular mods. It seemed good to start putting belt brand and part# information in one spot. I'm starting to look for replacement belts just to have one on-hand for my '03 since its bound to snap one day!
Lots of very specific belt information on this site from established members. When and if you purchase a belt confirm from your vendor of choice that it is Aramid Fibers & Polyurethane ribbing
As you know, cross referenced, interchanged & alternate part numbers assigned to the OEM P/N’s are typical to the cycle & auto industry and will not guarantee the quality of the substituted part.
