Michigan motorsports ls7 lifters
They worked out great so far2006 Silverado 4.8Be 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.

Eliminated the noise !!! 2006 GMC Sierra 2500
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.
