    Wrong size glad I checked u like the person who picked the order.
  

*by A***R on Reviewed in the United States 🇺🇸 on May 15, 2020*

I tried to use this product to rebuild a 4.060" bored 350 sbc but the piston rings I recieved are 4.040" . . . So they obviously wont work. The frustration sets in when everything on your order stats 4.060 piston rings yet someone couldn't take the very few moments to read the manufacturer's part number and insure they were doing their job correctly. The box my piston rings came in clearly stats, multiple time, in different fonts and sizes yet the picker never realized the box stats part number 40564cp.040 or the portion that reads size 4.0394" . . . Which is practically 4.040" smaller than 4.060" like the rest of order stats. If they can't send the right product what makes you believe they built it correctly . . . Garbage, straight garbage
