.020 oversize 4.2 V6 performance coated pistons. They are Silvolite units with the part number 3152HC + .5mm (.020"). I've checked Ebay, Jegs, Summit and a few other on-line companies and they range from $188 to $250. Save a bunch of money at $130 shipped to lower 48. If I can get them in a "if it fits, it ships" Priority Package, I will not send them in the original box but will package carefully. Please text me at 505-288-5580 for more information or pictures.
