maybe its jus the quality...but ever since i got a new alternator belt cuz the old one was finally done for after a good 2 years of running my car hard...the new one has been fraying and stretching alot quiker...it was pretty hard to even get it on cuz it was barely too short...and then im now maxed out on adjustment for all the way stretched and i think its getting loose cuz i hear alot of noise coming from there. any suggestions? i literally had this thing for like a month

 

That's weird. Maybe you put it on too tight to begin with and that's why it's fraying. Otherwise I don't know. All stock?
