Genuine GM parts
Genuine GM part in OEM packaging. I installed one on an LM7 5.3 and one on an LQ4 6.0. They are a direct swap using the stock gears, and are noticeably thicker.

LS2 timing chain on 5.3 LS
Installed on my 2012 silverado 1500 with a 5.3. Definitely an upgrade from the stock timing chain

Good stuff
Replaced my 305k mile oem chain as a preventive when doing an oil pump replacement. Surprisingly the old chain had little to no stretch when comparing the amount of slack, but here we are.
