Nothing I'd cozy-up to...

Proper belt tension, pulley alignment(and size)have worked well for a lot of years...

I've never had a V-belt failure...

Be it at the strip, or on the street...


(But I can tell you about a serpentine that got thrown on a vehicle I had...30 miles after I drove it off the lot brand new...

What a cluster-%*#& THAT was to get resolved)...
