Excellent

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.

The pins that hold the roller seem to be offset from center on lots of lifters.

Son de buena calidad

Advertised as LS7 lifters but highly doubt they are GM parts. No visual concerns with quality and all these lifters are pretty much just called LS7 lifters nowadays anyway... still false advertising if they are not. They took quite a while to ship as well and it wasn't free shipping. Would love to hear Mich Motorsports reply if these are actual GM parts or not...?
