    • 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. ... show more

My 2006 GMC Sierra 2500 HD 6.0 has 280,000 miles on it. At startup it was a clacker!!!! It then started happening on the freeway all the time. Finally decided to fix the problem. My engine purrs like a kitten now. My sure to get new engine head bolts and new exhaust bolts. Soaked the lifters while I was opening up the engine. Michigan Motorsports was fantastic!!! They answered my email quickly and were very helpful. ... show more
