ZR-1 Net Registry Forums - View Single Post - Aftermarket Belt Tensioner Pulley Failure

HAWAIIZR-1 · 05-23-2019

It’s hard to imagine that billet aluminum is weaker than plastic (stock) and I agree it has to be bearing failure with a seize that heated and burned by the belt friction. It would seem that would be noticeable though. I’m tempted to go back to stock myself. I guess another reminder to make America great again and we need better quality parts overall and stop outsourcing if this is from China.

I can’t remember the Dynomite post. Was it bigger and needed and larger belt too? If same sized belt used it could cause more tension on the pulley than it should have? Thanks for sharing since some of us did this mod.
