Looking into some piston options for a 12v motor, something with a larger bowl and drop compresion a lil. Curious where you got them from and ballpark $$
Thanks Brett

If the HP is kept under 700 and cp's are held within reason they should be fine with limited use.
zstroken said:Just cause Mahle makes the OE cummins pistons, doesn't mean they sell the same piston. Cummins could have supplier agreements with Mahle that prohibits Mahle from selling the same piston, or perhaps pistons using the same alloy.

1. Mahle marine
2. Mahle 155
3.Cummins Marine
Do you have a part number for the mahle marine piston in .5mm overVoodoo Trucker said:The 370 marine that Mahle sells looks exactly like the Cummins 370 marine pistons. It has dual steel ring lands teflon skirts. The Mahle come loaded, rings already installed and wrist pins. I will get the part number up. I have compared the Cummins marine to the Mahle marine side-by-side and they look exactly the same. I just overhauled a Cummins N-14 and M-11 and the pistons are two piece articulated design (steel crown aluminum skirts). Inside the skirts it has Mahle cast inside. I called Mahle to see if I could go around Cummins they said there contract would not allow them but, the contract time was almost up and we would see after market kits for the M-11.
Cummins uses two suppliers for there pistons Mahle and a company called something like Kopin Schmidt(?) This is what the tech guy at Mahle has told me.
By the way GM uses the same two company's in there Duramax. Mahle was used in the LB7 and LLY engines and Kopin Schmidt in the LBZ. Guess which one has the cracking problem...
You have at least 3 ways to do it:Voodoo Trucker said:I took some pictures of the Mahle marines I have and I tried to post them but, can't get it to work. If somebody wants to post them PM me with your email address.
