Any problems with 2009 LMM BONE STOCK??

...I see on here that people have issues with alot of things but all seem to be non-stock. My question is does anyone own a STOCK LMM and still have the same issues? I am at a loss here, I want to buy one but it seems like there is a lot of things that go wrong, especially in the winter. That is not something that I want to constantly worry about, so any input from the STOCK owners would be greatly appreciated. Thank you...

Stock is ALWAYS the best option. The problem with all of us is, we dont like stock. A stock dmax is built to run 250k is what gm states... When you power program it, exhaust, intake, you reduce the life of the engine and tranny considerably. Stock they will run forever.

I just got my 2008 LMM in Feb, got 5000kms on it and its bone stock.. I'm to paranoid to do anything that screws it up.. I like the idea of having a problrm free 500,000 mile rig or 800,000km for us north of the border. I haven't had any issues, I have lots of power to pass anyone on the road.

How fast would this stock LMM do 0-60mph? anyone know? Seems to have PLENTY of power.....

I have a 2008 LMM dually with 42K on it now and I am also paranoid about doing any mods. My LBZ had way more power after mods but I was freaked about breaking something! I think I may just do a DPF back exhaust for looks and be done with it.

Dude you are just full of mis-information.

GM/Isuzu/DMAX ltd. rates the engine at 250k miles. Yes they will most certainly go farther than that and PLENTY of duramax's are still running at 500k problem free, but 250k IS WHAT GM STATES.

Have you been to gms diesel tech school/classes. I am guessing not. I cannot show you any information backing this up. But I cannot also find any information backing your claim up. So I guess we will never no.

stock is the easiest,safest, and cheapest route to go if you are worried about messing anything thing up or having any warranty issues, as far as toypuller full of mis-information, um ya well, he hasnt mis-informed me in anyway for the questions i have asked him, and considering he is a dmax tech specialist, kind of hard to be mis-informed by somebody like that

Neither have you, with all the BS you keep feeding people, like "the duramax valves cant be adjusted", haha is that a joke?


Ill find the document that states the dmax's B10 life, which is 250k.

Do you have a link to back that up???

Are you not the same guy that said you can overheat your tranny and allow fluid break down and nothing bad will happen???

Interesting....
