Pulley looked like it was good quality. Just remember when order that you don't have the other style.

Good product. Removing my old pulley took a 1/2” wrench to remove the bolt. This item comes with a 15mm bolt head, which I didn’t have, so the project stopped while I purchased a 15 mm wrench. I have a 2003 Dodge Cummins 5.9. It took only an hour for this rookie to install. It would be very helpful if you had a helper depress the tensioner so you could slip the belt back on more easily.

Works great, better than the gates I removed that was already wobbly at 15K miles.
