Here's a good post to read if you want to know the differences between the LB7 piston and the Mahle race cast. http://www.duramaxdiesels.com/forum/showpost.php?p=536283&postcount=56

Ive run decked, delipped, uncoated lb7 pistons with no valve reliefs at 600-1000 HP for 4 years and 43k miles without any issues. Results may vary butt i've had good luck.

So has BigBird ( Kelly ) guy has a tone of passes in the 1000hp mark

I love the Arias for myself and Jeff has also had great luck with them

Have you had to re-ring them yet? Or I guess a better question is how many miles do you have on them?

Pistons

I wouldn't have any other piston in my race motor! Now if it were a driver that I wanted to get 100k out of I would just run the stock (cast) stuff and keep the power down. Im sorry but god can bless a stock piston all he wants and you still have a stock (cast) piston. They will only hold so much for so long. I wanted a race motor making race power there is only one option. A race piston. I do think a stock piston is the best option for a guy driving his truck every day. I just don't agree with a guy wanting to make 750 or more and thinking a stock piston will be fine. Just my thoughts and not worth much.

worth a little here... ive been reading the mileage and teardown reports from when you broke the motor down and it seems that people can get more mileage from the forged than initially thought.

Heard its suppose to help handle higher egts, and i only know what ive read from others that have done it. Im just gathering info from as many people as possible and try to make the best decision i can.

Don't waste your time.
Do yourself a favor and spend the extra 400 bucks to get the Mahle Motorsport pistons.
