Dont buy anything from those assholes. I broke a ring filing it to put in my engine. I was grinding it on a a wheel grinder and I had just squeezed it onto the wheel to grind it and turned the wheel maybe half a turn I didnt even grind the black finish off the tip of the ring and it snapped clean in half. It is obviously was a manufacturing defect. So I called JE and told them what happened the speed shop had already ordered two more from them and ahd charged them so I decided to call JE myself and tell them what happened and see if they would handle the situation correctly. I even ahve pictures and would ahve gladly emailed them to them to show that I hadnt modified the ring and the condition it was in. Well the dude answered the phone with an attitude cause the operator obviously told him what I was calling him about. He told me he wasnt going to warranty the ring and basically told me f**k off. I told him anyway what had happened that I had pictures of it and you can see how the metal failed and that I hadnt even ground off the black finish off the tip. He told me that I had modified the ring well OK it is ment to be ground where I ground the mofo at its not like I was grinding the opposite side of the damn ring. Thats BS they are a huge company and hsould stand behind their product. I could udnerstand if it was in the motor and I burnt a ring but damn it wasnt even ground right before the POS broke. He proceeded to tell me that it wasnt going to be warrantied and to have a good day. I ahd a few good words for him and hung up. That is just piss poor customer service right there. They get the rings for cents and it would have cost them ac ouple of bucks for shipping that isnt hitting them hard in the pocket book. I just gave them 700 bucks for a set of pistons the least they could do is send me a damn ring. SCREW JE pistons I will NEVER buy another set from them and I hope everyone that reads this post will not buy their products either. Rant off
