It worked for my 2013 Yukon 5.3 LMG
Wish I took more pictures between rebuilding 5.3 LMG. These rings are working great. I did check all Piston Ring Clearances. All old bearings looked good after 224,000 miles. Just rebuilding to delete the afm dod while the engine is out. Assembled and driven for 6 months now.

Great product
We all know that Hastings is a leading manufacturer of piston rings, and the rings come prepped measurement will be required, but not necessary. You can’t beat a hasting ring.
