Hey all-New to forum and just purchased 2004 DMax. I see that LLY apparently started mid 2004. Wondering how I know whether mine is or not. Thanks in advance. Lovin my truck!

I think it is the 8th digit of the S/N if it is a 1 it is a lb7 and if it is a 2 it is a LLY.

Thanks for the help! Is the the general consensus? Sorry if this is a dumb question.

No dumb questions, that is how ya tell, plus looking under the hood and seeing if the injectors are out.

Something else I found funny is that the early LLY's were 590tq and then when cummins went to 600 GM then turned up the wick to 605ftlbs.

....... and then, according to a post by Hoot a while back in the Dodge topic area, Cummins then turned up the wick to 610 ft lbs.
