Cool, Yeah i think they will look good with a lift on them. With that big a$$ front end on them they sit to low to the ground!

the new body style is growing on me enough that my next new truck is going to be the Chevy 3500 LMM S/C L/B SRW,but my favorite is the 05 thru 07 classic body style...

question there you mentioned you bought a new truck and you called it the LTZ,are meaning the LBZ or the new LMM....if you have the new LMM or new body style gm brought out it will be hard to find performance parts for it due to the epa regulations,but if you have the classic body style you'll have the LBZ and there are plenty of options avalible for it...

it is a new body style lmm the ltz is the package it is what replaced the lt or lt3 packages: i understand performance upgrades will be a ways out but your screen name refers to tires any suggestions on lifts i have priced out a 6" fabtech for 2,550 installed 20"kmc chrome hoss wheels 449 each and 35" nitto's for 348 a piece how am i doin. also anything else to think about when lifting a truck gearing or anything otherwords there is enough power to get a guy buy thanks for any help in advance

the legs
sorry about that i didn't know they changed that....how do you like the ride compared to the older gm trucks?with 35's you won't need more then a 4" lift on the new gm trucks with a 6" it will look better with some 36's or even 37's but anytime you step above the 35's you will really jump up in price per tire....

pm me and i can get you some prices but check with the other sponsors first since they are sponsoring this web site,i don't want to step on any toes...

RIGHT! I realize now I've committed a "Duramax Faux Pas". I'm new to this game.

Has anyone out there calculated "fuel mileage" on the new LMM Duramax?

I had a set of (5) 35" Nitto Terra Grapplers (for an 18" wheel) on my Duramax. I paid $250 ea. for them. I got them from Discount Tire Direct. I paid extra for high speed balance specific to a truck tire. I got 55k out of them and they wore evenly. DTD will balance and rotate for free if you live close to them and go there. They have a website where you can purchase also. www.discounttiredirect.com See if they're near you. They sell good wheels cheap too.

On my '02 Duramax, I installed an RCD 6" lift (No 4" was available) that was cheaper than $2,550 installed (more like $1850). I went with RCD because at the time they were the only company who made a custom spindle that wouldn't interfere with the stock alignment, nor did I have to cut anything to install. It comes with Bilstein shocks (the only co. to offer that at the time) and my truck rode smooth like a cadillac and it handled really well. It held it's alignment forever and I go over curbs and logs on site all the time. I recommend that kit. They make a 4" kit now.

I put in a chip to help out because power was lost with the 35" diameter and 3.73 gear. With the chip the truck was awesome. I hear that changing gears to at least a 4:55 will help but that is huge money and I didn't want anyone to open my diff. I would advise to get something to correct the speedometer (mine registered 10mph slower). Otherwise the taller gear didn't matter as my power was more than enough.
