Will be hopefully gettin a dmax here pretty soon and cant decide what truck to get i dont care much for the new body styles of the LMM Dmax. But on the other hand i really like looks of the 06-07 LBZ. As of right now i'm thinkin i wana go with the LBZ. I plan on putting a lift,tires,chipped etc. on it to make it a good lookin truck and everything. I dont live to race everytime i pull up to somebody but i would like to have a truck thats still has enough power to show that it isnt just about looks. Guess my main question is what are the stats like on the LBZ compared to the new LMM can you make an LMM faster than the LBZ or is the main difference just the body style?

Still fairly new to the Diesel World so just bare with me on the stupid question i may have asked.

Thanks,
Luke

keep in mind LMM does have a diesel particulate filter, dont know your stance on warranty and power adders but could potentially create warranty issues QUICKLY. LBZ is great, easy to get it to move even quicker than it already is. No DPF to have to screw around with. This is really a matter of how much do you want to spend?

LBZ BABY!!!! last of the dying breed! last version of the d-max WITHOUT most of the emisions crap! ask anybody who owns one.... including me :)!!! excellent power & reliabilty! but seriously i dont recall their being any increase in hp or tq from the lbz to the lmm.... but good luck finding a lbz.. most guys buy them and KEEP them!

Go with the LBZ you will not be disappointed!

I dont want to go and drop a bunch of money into it but i would like a truck thats a good lookin truck which is one reason i'm liken the LBZ more than the LMM i like that body style over the new ones. But with the looks i want it to have enough power to show that it has more than just the looks. Ya know what i mean?

All that i really want to do is like a good lift leanin towards cognito, good set of wheels and tires, exhaust etc. Some interior work to make it look good on the inside as well maybe even a custom paint job i dunno. And like i was sayin and i want to give it enough power to show that it has more to it than just looks.

Thanks,
Luke

LBZ man. and btw i know for sure the lmm has 5 more ft/lb torque than the lbz dunno about hp. if i was to do it again id do another lbz. never an lmm too much crap to deal with to get the hp/tq you want

I had the same problem right before I bought mine last year. I went with the LBZ because it was the very last truck before the gov ruined diesel with all the emissions crap. Ill never worry about being tested, and I can keep my warranty and run a turbo back exhaust and a chip (with my dealer at least).

I liked the looks of the new trucks and they have cool features, but figure 1200 bucks added to the cost of an LMM for DPF delete if you want any kind of mileage, and say goodbye to your warranty if you have any problems. My buddy has an LMM and he gets 12mpg. Last weekend on a 700 mile trip I got 19.3mpg running at 80 mph. Also I can run any kind of fuel I want. At some stations in TX and AZ you can get Low Sulfur instead of Ultra Low Sulfur. Its cheaper and runs a lot better. Also, I have the option of running any other grade diesel I may have available and not worry about screwing things up.

For a lot cheaper than a cloth interiored LT 2008 (like the old LS), I got a 2006 LT (leather, loaded, like the new ltz) with a couple miles on her. I plan on driving this truck till diesel is no longer produced as fuel. Im glad I got the last of the good ones.

The differences in HP are LBZ @ 360, and LMM @ 365. Ill give up 5 stock hp to never be hasseled about emissions. The way things are loking they are going to get real serious with this emissions crap. They are putting that crap on new farm and construction equipment now.

So in my opinion, buy an LBZ for sure, you will not be dissapointed. It was probably the best decision ive made in a while!

I hope you guys realize they're the exact same motor with minor tuning and exhaust differences.

I realize its basically the same motor, but I wont get bs from my dealer when I come in for warranty and they find low sulfur fuel in there and no catalytic converter. If you do that with an LMM with no DPF they will laugh at you and your warranty will go down the drain. All that and the fact that I will never be checked for diesel emissions by the state (at least in TX) makes the LBZ a better choice for me.

I had a choice and I went LBZ. I really like the new style and miss the power sliding rear window. Plus its nice to have the new style of anything looks wise. I just didnt want to deal with all the emissions crap. Some days I regret it, most days I dont ):h

At least in 2010 when I pick up a 2009 because of the tier 2 emissions that are coming all my mods will work on it for the most part.

LBZ also has 10 less ft/lbs torque, but the lmm dpf will ruin any power advantage over the lbz anyways. Not to mention if your planning on adding a program it wont matter. Go LBZ so you dont have to worry about the emissions BS.

this thread makes my decision even more comforting. i plan on buying an '07 classic LBZ this weekend. i have been liking what i have been hearing.

You will find that us LBZ owners are very particular about our engines. Most , like me, would not part with theirs for anything. Think of it like this too- which truck is less likely to have problems, the first years of a model or the last years of a model that has had the bugs worked out of it. (I know, near the same engines, blah blah...) for instance, the early powerstroke 6.0 had tons of problems, but the last ones have few problems at all.

I agree with everyone here. I just bought an LBZ a month ago and would not go any other way. I will admit the LMM have nicer interiors but to me the exteriors are already looking dated. The Classics are in my opinion always going to look good. They have the right combination of curves and angles. If you debadge them they look that much better. The NBS is so blocked off and after two years already look dated. Go with your gut...LBZ, Better looks, less emission crap..

They are both great trucks. Like the lbz a little more.

Well alright thanks for the input guys looks like i'll be gettin a lbz now i just gotta find one.

If you want the "other" side of the story, post this ?? over on the LMM board, pretty sure you'll get the exact opposite answers. :D I've been without the DPF for about 15K miles now, not a single issue. I can get 21mpg on the interstate with CC set at 73mph, (with 33's). Get about 15-16mpg around town. I think the big picture is, you can't go wrong, either will be more than enough truck, stock or modded. Chris

:exactly: :D Mike

Go with an LBZ.. Less emission BS and not as many warranty battles with GM..

Power making ability they're on par(if emission crap is off both)as they are on MPG, seeing mechanicly they're the same.. All depends on tuning, that's a given.

I think the GMT800/880 is a better looker myself inside/out.. The GMT900 HUGE front end looks dumb and the interiors are tacky/cheesey with the euro look twist knobs and the gauges with GM's poor attempt at retro-modern are yuk..

You'll find bias for any series Duramax fact is, they're all great, make ALOT of reliable and efficient power and are the most advanced and user friendly turbo-diesel on the market..

Whichever you chose LBZ or LMM it will be a wise one.. Good luck with your purchase!!

I have an 06 LLY, basically a detuned LBZ, but I'm looking to get into a new body style. The cabs inside and out seem to be much better quality in the new trucks, much quieter and everything lines up better.

For me the motor doesn't really make a difference, get rid of the emissions crap and with some tuning its basically the same. I still like the look of the classics, but the new GMC's has really grown on me. Don't care for the new chevy's as much. My two cents.

There both great trucks.I have a lbz and I love it.

Is there such thing as few problems on a 6.0L PSD lol?
for instance, the early powerstroke 6.0 had tons of problems, but the last ones have few problems at all.

The NBS has such thin sheet metal, find what people say about the hoods, dent very easily. My dad dented his with his gut leaning into the box locking 5th wheel pin. The new ones seem to sqeak more and leak wind worse IMO.

I read some where, probably on this site, that once an programmer is used on an LMM, even if it is later returned to stock, it leaves a signature which the dealer can find, which in turn allows them to void your warranty. The same is not so for an LBZ. Just another reason to go with an LBZ.

after two years of the nbs being out, it looks even better to me and your classic looks very non current

where do i look to find if it is an lbz?

inside the door panel on the jamb?

x2 it is really startn to grow on me :D I used to kinda like how the 06-08 fords looked but dont like them now:chevy: the silver color that is on my truck sure does look good with dust and mud on it:D

Well to each his own. ;) You cant go wrong with either truck. I plan on keeping my truck for many years to come and think that the Classic's styling will look much better when they are 8-10 years old than the NBS will.

On the vin, look at the 8th number. Should be 3 like xxxxxxx3xxxxxxxxx

1 is lb7
2 is lly
3 is lbz
4 is lmm

i just checked it and the 7th number was a 3 and the eight was a D:confused:

i am assuming that is what you meant

The 8th# in the VIN code go this way..

LB7- 2001 to 2004, VIN code 1
LLY- 2004.5 to 2006, VIN code 2
LBZ- 2006 to 2007, VIN code D
LMM- 2007.5-present, VIN code 6

good deal. i just bought an 07 lbz then:ro)

08 is a diff body style than an 05-07 super duty...

good deal. i just bought an 07 lbz then:ro)

If its an 07 classic its an LBZ:banghead: No question there...

LBZ all the way. The LMM's suck in my opinion who wants that damn dpf filter anyways. Straight pipe it and let it scream.

your truck looks dated, dpf is not a problem, people just talk and say it is but have not heard of any blowing up because of the dpf or even problems from it. ive had both and the lmm walks all over the lbz in looks, quietness and throttle response. plus they always improve the duramax with every new one that is made. lmm imo has better injectors and turbo

Well to each his own. ;) You cant go wrong with either truck. I plan on keeping my truck for many years to come and think that the Classic's styling will look much better when they are 8-10 years old than the NBS will.
ya your right, i liked my lbz, just like my lmm better. your trucks design is like already like 10 years old lol

It looks like we have upset the LMM owners. Let me get out my tiny violin.......

ya your right, i liked my lbz, just like my lmm better. your trucks design is like already like 10 years old lol

Ok, you win tough guy. It is official...the LMM is a far superior truck. :rolleyes:

as far as i know they are the same engine, pulling the dpf doesnt cost any more than straight piping the lbz, either one with enough money spent will be wicked fast....i can say this though...ive drove them all and the lmm is one pulling s.o.b.!!

Ok, you win tough guy. It is official...the LMM is a far superior truck. :rolleyes:
sorry to hurt your feelings....:rolleyes:

So if you were to just make it an issue of chassis selection, say both had an LBZ drivetrain, no emissions issues, which would you prefer?

-P.

I've owned both and the LMM gets better mileage.

especially when the regen kicks in ! :o:

I am averaging around 2 mpgs more.

I've got a 07 Crew Cab 4x4 dually LMM and get 18.5-19 mpg highway driving...completely stock. Been very happy with it.
