I have a 6.0 lq4 I recently purchased a set of stock replacement pistons for. The seller thought they were .010 over but wasn't sure so upon receiving them I took some measurements and they are 4" diameter same as the bore size so does that mean they are .010 over or .005 I tried to find Lq4 stock piston diameter but no luck any help would be appreciated thx.

Just a standard tape measure I will be taking the pistons in to work to use my mic for a closer measurement

you will get different measurements depending where you measure on the piston also so be aware. I was told by JE that they measure 1" up from the bottom of the skirt across the skirt. add a few thousandths to that and that should be the bore size.
