Details:

Have any questions or want more photos, feel free to message me, Sold as-is here is a Gen 3 LS 4.8 crankshaft. Harmonic balance bolt threads look and feel nice when is installed. 24 tooth wheel. Flex plate bolt holes are good as well.

See photos for exact detail. Removed from a running engine. Sold as-is as a core, but would be good to run in my opinion. Main and rod bearing surfaces look good, have been lightly buffed by hand.

Timing gear looks good as well. Has been thoroughly checked, cleaned, and oiled to fight rust. Standard bearing sizes.
