Very smooth, very quiet operation, just like factory
I will only buy GM original parts or ACDelco for my 2005 Z71 crewcab. I’ve been down the fraction of the price, can’t pronounce the name parts from Amazon and will not go down that road ever again. OEM is the only way to go. Especially on a part like this that is constantly moving and needs to last 60,000 to 120,000 miles. My previous one (OEM) was on there 116,000 miles. I’ll take that again. So I’ll pay the extra and not repeat this and have to buy another one in a few thousand miles. ACDelco Gold is the ticket. This thing fit perfectly, and zero noise. Smooth as glass operation. My old one was rubbing on the tensioner arm, making a scraping sound.. wore out. The new one looks purty under there. And works great. Always buy OEM, GM original parts or ACDelco only. You won’t be sorry, but trust me.

Fits like OEM
Feels and looks like OEM. This item was a breeze to install and had a much smoother operation than my old one that i had been neglecting to change. It gives the engine a cleaner look and eliminated the slight squeal that the old one was starting to make.

OEM all the way!
This belt tensioner is currently installed and running. It has not failed like the knock-off which lasted less than a year. If OEM parts are available do hesitate to buy them, even if the cost a little more - you won't be sorry.
