    DK pistons, junk or good?

    Here is how I see it. The 6.4l fords and duramaxs have piston cracking issues. Everyone blames the piston composition and design, which is somewhat correct, but there are also many other factors that can cause a piston to go toes up. For instance, bad injector spray patters will superheat some...

    DK pistons, junk or good?

    Thanks, I had his number in my phone and lost it. My dumb butt self can't find it on here. When I pull down the top tab, it don't show a vendor option.

    DK pistons, junk or good?

    @Bdsankey hey, how do I find your products for sale? Unfortunately, I have the pistons ordered already, but I am going to need more parts and will need more in the future as well. What all do you sell? I contacted you once for a customer, but he ended up backing out on buying from you. Are you...

    DK pistons, junk or good?

    No, I am not. I had this username handle before them though. I seen their stuff before. I don't really do the social media stuff. I have some stuff on YouTube, and that's about it.

    DK pistons, junk or good?

    Well, I think Bdsankey pretty much settled the discussion here. I wasn't saying mahle is junk either, I use them all the time. I just was stating that some of their products come from China, and that rubs people the wrong way sometimes. As long as it's good, then I don't care where they come...

    DK pistons, junk or good?

    So, dumb question, couldn't a person just have the machine shop delip some mahle pistons? Also, they say the rotating assembly has to be balanced with these? Why I wonder?

    DK pistons, junk or good?

    I just looked on their website and they charge a 20% restock fee on returned new parts. They got me coming and going. I need to quit being so gullible. ? That's about as bad as harbor freight. Heaven forbid you inconvenience someone to hit a few keys on a keyboard and walk it over to a shelf. Oh...

    DK pistons, junk or good?

    Forgive me for the million questions, but you are the guy in the know. I know Mahle has a huge global presence, including China. However, as you mentioned, Mahle Motorsport is strictly a US manufactured product from Morristown TN. DK pistons are NOT Chinese made. Their manufacturing facility is...

    DK pistons, junk or good?

    Actually, Lincoln Diesel Specialties has a good price on some Mahle pistons. Only 660 per bank. That's not bad at all. I am sending the dk ones back, since you guys think it's a bad idea. I can get a Mahle set for 320 dollars more than the DKs.

    DK pistons, junk or good?

    They already shipped, but I may just call and return them when they are delivered. I don't want to tear into it again, or waste a good block on bad pistons. I have a couple lmm blocks laying around and a couple sets of rods. I don't have much in the build. Maybe 3000 right now. My machine shop...

    DK pistons, junk or good?

    Well, have you guys heard bad things about them or seen guys have problems with them? I didn't strictly order based off of the sales pitch. I was reading some reviews from powerstroke guys and there was quite a few praising them as being good quality. However, I couldn't find much from the...

    DK pistons, junk or good?

    Well shoot, I just read your reply. I called DK this morning and got a really nice guy who kind of talked me into a set of pistons. He claimed they were exact replicas of Mahle. I asked him if it was the same alloy composition and he said yes. He claimed they were identical in every way. He was...

    DK pistons, junk or good?

    I am working on rebuilding my personal service truck with an lmm in it. The cam pin sheared and bad thinks happened from there, as you all well know. Anyways, I stripped it down and to the machine shop it went. They called me today and it made .020 over on the bore. I just had them turn and...

    Need connector end view diagram for 05 lly

    I am working on a 2005 lly duramax. I have alot of bare wires on the c107 connector. It has a hyraulic hay bed on it that leaked hydraulic fluid down into the wire loom of the engine jumper harness at the c107 connector. Its going to be a fun one. Anyways, I was wondering if anyone had the...

    Lml ecm pinout diagram needed

    Lml ecm pinout diagram needed

    As for what I have did so far, I used the diagram from 2004lb7 that's posted above (thanks again) and used the diagrams from Haynes that I have and checked the data pins from the ecm plug to the gpcm and could not establish continuity or high resistance. It simply showed open or OL. I removed...

    Lml ecm pinout diagram needed

    I went there to check it out, and it sure has a wealth of knowledge there. However, it didn't seem to have the diagrams I needed, unfortunately. I have a Haynes schematic of the comm wires, but it doesn't list pin numbers, nor does it say where the comm wires go. It simply says "to computer data...

    Lml ecm pinout diagram needed

    Ok, thanks. I wasn't sure if I posted this one in the right category. I seen other similar threads posted in hard parts, so I started a new one in the other category. I wasn't sure though. Thanks for merging it. I am still new to the forum layout.
