I used these pistons for my 4.0 rebuild. I had my block bored and honed to .020" over. All the pistons were stamped as .020" over. On the break-in, the engine developed a knock.I disassembled the engine and found considerable scoring in one cylinder. Turns out the piston was .020" undersized! I reached out to the company but it is a subsidiary of DRiV Parts and I've been unable to get any response after several emails and phone calls. The block had to be re-honed to .030" and I had to purchase all new pistons pressed on to my rods. Not cheap.I would avoid this manufacturer and go with a better brand like Icon.
