Review: Michigan motorsports ls7 lifters - They worked out great so far 2006 Silverado 4.8 Be aware they make a lot of chatter at first start up at least for me. Noise lasted about a few seconds. 2nd time it made a even louder knock/ lifter noise. I shut off my engine started it again and went silent better then ever. So far so good. I would recommend and purchase another set.

### ⭐⭐⭐⭐⭐ Seems to be good quality. Package was torn on arrival.
*by Z***N on December 11, 2021*

The product looks to be a good GM replacement lifter. I see there is some questionable reviews on this product. The trays have the GM part number. And the product was shipped in the company package. The lifters were shipped in oil, and they look to be correct for the LS7 application.
