Perfect fit.
Perfect fit for my 2007 GMC Yukon Denali. Seems to have stopped my belt squeaking. Super easy to put on.

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.

Works okay. 07/08 5.3 Vortec Silverado
07/08 5.3 Vortec, Silverado. Easy fast install. Feels heavy duty. OEM at a fair price. So far okay. Pulley is identical in material as the original when vehicle was purchased new. It is non metallic but very sturdy. The old pulley still looked brand new.

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.
