2005 Chevrolet Duramax

Hey guys, was needing some help regarding a truck. I have been looking at a few diesels and I am more familiar with the powerstroke and cummins compared to a duramax. I really was wanting to find a 5.9 cummins, but I came across a mint 2005 duramax that is loaded. Its an 05 125,000 miles, exhaust, lift, rims, and all the good stuff. I was wondering is it a good deal for 19k, and how the LLY 6.6l duramax engine compares to a 5.9 cummins?

I just paid 20k for mine about 3 months ago. Same deal as yours but bone stock with 112k. ecsb. fully loaded (leather, sunroof, the whole 9) So far I spent about 5k on tires/wheels/lift ect. The lly's have a little reputation for headgasket issues. I think its hit or miss, depending if the truck was used to tow with or was abused.. I am real happy with my lly though and so are many others.

Is the 5.9 a 12v, vp 24v or commonrail? Like 3 different animals. I'd compare a duramax for a 5.9 commonrail only.

Another thing you gotta think about is the trans setups. The LLY came with 5 speed allison, vs the lbz which was the first year for the 6 speed allisons (06 and newer). I don't know much about the commonrails trans, but I do know they suck. My buddy has 87k on his commonrail and just put a trans in his. Just some more things to take into consideration.

That's not a terrible price. I'd try to pay 18 out the door. With it lifted I would check the wheel bearings and other front end components for play. will be pricy if they are all shot

When test driving make sure you get a good WOT run in, if there is any trans slippage or limp the guy has most likely toasted it with abuse on high tuner settings and the big tires

Other than that just crawl under it and check for any leaks

There are a few things you'll wanna do on a LLY such as upgrading the factory turbo mouthpiece and a few small things.

Overall LLY's are badass trucks and if it is clean and well taken care of I think you'll be very happy with it over the dodge

06-07 is the most sought after year, but that doesn't mean the LLY's aren't totally solid trucks. I'd drive one, just got a great deal on current pickup

The Dodge is a 2006 lone star edition, I haven't went to see it yet so I do not know if it is the 24v or 12v but I am sure its the 24v. Also, the same with the transmission, I do not know yet. The miles are about the same on both. I really like the way the Chevrolet sets up though, looks really nice. I just want to make sure I am getting a good dependable truck, also how does the power, MPG, compare to these 2 engines? I am wanting a good sounding, throaty truck and decent MPG. Thank you for the responses

Heres my 2 cents. Thats a commonrail 24v. I have driven and rode in my buddy's 07' commonrail many times and own an 05 lly so i feel Im a reliable source. I personally like the interior on the dodge better then I do on my chevy. As far as roominess, my extended cab has just about as much room as his crew cab, but then again, your the one driving and not sitting in the back. The trans in the duramax will outlast the trans in the dodge by a longshot, except if its a 6 speed manual, which it probably isn't bc there a little hard to come by. Here are some numbers to compare..

The dodge has more room under the hood to work and the cummins is easier to work on then the duramax. As far as sound, the duramax sounds way more badass, especially with a stock down pipe IMO.

Test drive both trucks. Its more personal preference. I'd take the duramax and my buddy also wants to sell his cummins for a nbs duramax also.

Thank you for all the information Chevy! I'm not a guy who will be pulling with it, as I saw they had some bad reputations for overheating, so I am not worried about that with the LLY. I saw where I can get the mouthpiece for the turbo too, do you know how I go about that?

That's not a bad price on the Chevy. Like others said, 18k would be a little better. I just bought a truck that is nearly identical other than the color and wheels about a month ago. It had a few more miles, and a few performance mods, but the asking price was very similar to the truck you are looking at.
As far as mpg, it varies. I have a mild tune, 4in exhaust, and the other stuff in my sig, and I can get 18-18.5 if I drive it right. About 17 or a little more when I play around some. I would guess the dodge might get a little better mileage, but not a huge difference. The tires on the Chevy may hurt it some.
Like someone else mentioned, head gaskets front end parts would stuff to look for.

My buddy commonrail gets about 17 mpg on 37's but his is efi live tuned. I get about 14 average and my truck is bone stock on 33's. We both drive fairly easy. MPG's can be a large grey area. Everything you do to the truck will effect it, such as exhaust setup, what tunes you choose, tire size, and even how heavy your foot is.

Your going to look for a LBZ mouthpiece. They are less restrictive then the stock lly mouthpiece. AFE sells one, you can get them on xtremediesel's website and im sure many others.. they are around $250 i believe. I think you can get an LBZ mouthpiece for around $70 bucks. Just google search that bc im not sure who sells em. I'm going to get an LBZ mouthpiece once my damn tax check comes
