Review: Excellent
Review: 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.
