from a reliability stand point LBZ, no cracking injectors, no over heating problems, and most power/torque in stock trim, strongest block...... 6-speed Allison, need i say more?:tttt:

the LMM is the same as the LBZ, but it has a few more EPA required bits

Yeah but with the lmm you can just buy a new tuner and delete all the emisions bullshit:argh:

What years are which?

I'm in the starts of shopping for one. This one was to be more creature comfy according to my wife.:bat:

Your Gonna want the 07.5-10 LMM:rocking:

I have had an 03, 05 and 07.5, of them all my favorite is the 07.5, but when I bought each of them the newest was my favorite, if I bought a brand new one, it would probably be my favorite.


Chevy/GMC Duramax 2011 LML

Chevy/GMC Duramax 07.5 & UP LMM

Chevy/GMC Duramax 06-07 LBZ

Chevy/GMC Duramax 04.5-05 LLY

Chevy/GMC Duramax 01-04 LB7

Chevy/GMC 6.2L and 6.5L

I like my lb7. Don't get me wrong. If I could afford it I'd be rolling in an lmm :D

If i could afford it i would be rolling in an LML Denali.... i got wood the first time i saw one:pca1:

as of now im likein my 07 LBZ.im not a fan of the the 7.5 styling in or out.i also spend a lot of time off the road n you seem to get better ground clearance with the classic GMs.i also didnt want to have to go thru the BS of deleting the DPF.i still wanted a truck under warranty.just my 2 since :yeah:

LB7!!!! :jump::jump:

im happy with my lb7 plus it has no epa bullcrap on it they are easy to get power out of
but lbz's have a lot beter block and crank :tu:
