questions on d max?
 

i have had ford and now a dodge cummins love the cummins.I was wondering how the d max is never hear much other than the truck is kind of soft suspension when towing true? i like the chevy but how is the d max all years?

really the early ones (LB7) had the injectors problems, i think it was the LLY that has the overheating problems, the LBZ im not really sure what the big thing with them was and the LMM is the newest one and it just has all the emissions stuff on it:argh: Duramax guys dont kill me if i got the names wrong :run:

i think the only thing with suspension is the IFS is if ya get into high HP and Torque but other wise its a pretty good truck with a few quirks just like all the other makes:ok1:

All you got to do is get some billet Sleeves that really takes care of the weakest pint in the IFS. Im not a fan of IFS but they do ride like a Cadillac though.

yeah they do it'll put you to sleep when your riding in them

The Duramax trucks are an all around well built truck. I love mine. I have a 3rd gen LBZ. They are very reliable and have hands down the strongest transmission from the factory. I pull a 38' 5th wheel alot.. generally at least once or twice a month. Each trip being over 300 Miles each way. Pulls it real good around 90 or so..:w2:

They duramax is the cheapest of the electronic controlled trucks to upgrade. Since the Allison trans holds better than most factory trans from Dodge or Ford. Its not hard to make 450-500 RWHP with a good programmer, shift kit and exhaust. Our stock airbox's are far superior to the others stock airboxes IMO.

The 1st Gen DMAX 01-04.5 (LB7) has the toughest pistons of the 4 models. Also had a wastegated turbo and 5 spd allisons. Some of the LB7's had injector issues, which were covered by a 200,000 mile warranty. And a some other LB7s had some minor overheating issues. Which there was a somewhat easy fix for.

The 2nd Gen DMAX 04.5-06 (LLY) is a great motor, and exactly the same as the 3rd gen (LBZ) with a slightly different tune in the ECM. The 3rd Gens were available with the ZF-6 or 6 spd Allison. Great Motors. As a matter of fact, there is a Land Speed Record set with an LLY that I believe had stock injectors and stock turbo. Ran 174 mph. The LLY's, often reffered to as a LiLLy, have a variable geometry turbo.

The 3rd Gen DMAX 06-07 (LBZ) is exactly like the LLY. They have little to no problems as of yet that I know of. Available with a 6 spd allison and a RARE handful with the ZF-6 manual trans. The main issue that I know some LBZ's had was some EGR system problems. Covered under factory warranty.

The 4th Generation DMAX 07.5- Current (LMM) is a great motor but has a DPF on the exhaust. Which of course is easy to get around these days.

All in all GM's Duramax is an excellent setup. I, of course, am biased. But with some good tuning, and an exhaust and shift kit.. you would be hard pressed to make 450rwhp out of any other trucks.

Alot of people dont like the IFS (Independent Front Suspension) for whatever reason. Truth be told, unless you do serious offroading, or just enjoy a rough ride, IFS is where its at. Sure, the tie rods can bend if you make over about 400 HP @ the tires, but there are some very inexpensive fixes for that. Tie Rod sleeves are readily available under $150. And several companies offer complete HD Tie Rods for a little more. There are several 1000+ RWHP Duramax trucks running them with no issues.

Hey, gimmie a break.. thats just what I could think of off the top of my head .. lol

:rolleyes2: now your just boasting

if you have anyhting 05+ its gonna ride good. IMO even with a lift and 35's my 06 still rides well. when it was in stock form it was it was also a very smooth ride and tha was riding over a straight axle..
