    Installing these on my 5.3, the ring gaps are inconsistent some measured .0030″ out of the box. Some measured tighter tolerance. Luckily I’m boosting this engine. But be mindful with these piston rings. Check Ring gap!!

    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.
