When is GM going to put a duramax/alli. in a suburban. Seems like the perfect combo ever for a hunting/rec. rig. Any thoughts?

Sorry but from what i have read the Suburban body stile will not let the Allison Trans fit. So it will be 2007 or 2008 B4 the body change. http://www.dieselplace.com/forum/smileys/Cry.gif Edited by: Snow_Dog

GM is working on some new transmissions to put behind a de-tuned duramax for use in their G-van sieries. So it would not suprise me to eventually see them in the suburban.

I remember someone attempting a Diesel Conversion for his Suburban. Donno if it worked or not.

I have heard rumors that GM is going to have a V6 Duramax that is 5.0L. It could be used ahead of the 4L80 trans in the existing 'burb/Avalance platform. Probably '06 before we see it, if it happens at all.

i have been wau=iting for that exact combo, are in a yukon, and will not buy till their is one, what a hoot that would be

Couldn't you just use a 2" body lift, just like the HD's have....then the Alli would fit? The truck would look a bit strange, but nerf bars or runningboards would solve that.

Someone else posted pics of a custom DMax Alli Suburban that was on ebay a little while ago....it had a body lift.

I think GM is missing a big opportunity here, IMHO. Jeep is putting a I4 common rail diesel in the Liberity. 22 city 27 hgwy. A V6 DMAX would be VERY appropriat NOW!! NOT in two or three years! I don't understand why the V6 isn't already in production. Oh yeah, they had to redesign the top half of the 6.6 DMAX and design a new 8.1 DMAX or 8.4 or whatever! Yah! we needed a bigger more powerful DMAX cause the 6.6 wasn't powerful enough for the big trucks? :eek: What a bunch of crCensored p! WAKE UP GENERAL MOTORS!!!!!! Fuel costs a bunch and it ain't gett'n cheaper! We need power AND economy! I guess I will be trading the old blazer in for a Jeep for the daily driver.

I'm looking to re-engine my Quadrasteer Yukon XL with the Duramax/Allison combo soon. The swap is relatively easy to do for those few out there who have done it before. Easier to start with a Suburban/Yukon 3/4-ton 2500 with the 8.1L gasser front clip and it's existing drive-by-wire set-up. This is necessary to accomodate the Duramax's radiator and associated plumbing. Hydroboost brakes are also a must. Yes, the 2" lift is incorporated, but it is pretty sano. Install looks factory from the samples I have seen. The set-up needs a custom driveshaft, but that is a straight forward job.

At this past year's Auto Show, the GM Truck reps said "they knew of one Diesel Suburban running around the testing grounds", but they had packaging problems getting the Duramax/Allison combo to fit.

I don't know why GM has insisted the Suburban/Yukon did not have the room for the swap, they could have done it. I think the bean counters slammed the idea. A Diesel Suburban/Yukon XL would have probably been considered a passenger vehicle, not utility vehicle. The GM Suits probably didn't want to blow out their emmissions totals for passenger vehicles, and that the EPA would lump the Diesel Suburban/Yukon in with the rest of the passenger car line-up. The fines would have been an issue. That's probably why they are waiting to release a diesel SUV, once the new diesel fuel reformulation goes into effect in 2006.

I for one plan to swap my 6.0L gasser out for the Duramax/Allison by years end. The 6.0L swap is possible, but takes more work and parts to complete. I want to keep my Quadrasteer, as long as she can take the diesel's power. I'm still trying to determine is it will. If not, I may sell it and start the project with a new 8.1L rig.

I don't have much information but there is a guy in wauseon ohio who does duramax allision swaps into suburbans, I seen a article about a year ago in one of the four wheel drive magazines

BigD, I saw that same article... Sweet....

Actually, my only reservation at this point is the lack of a warranty when purchasing a new vehicle for the engne swap.

Its my understanding that limousine coach builders are able to deliver heavily modified vehicles with the factory warranty in place to cover the factory portion of the converted vehicle. This would mean that a stretched H2, Caddy Escalade, etc. would be factory warrantied, except for the chassis plug and driveshaft, which is covered by the coach builder.

Since this conversion only uses factory GM parts, with the only aftermarket part to my knowledge being the custom driveshaft, would (or should) the converted Duramax Suburban keep its warranty largely intact?

With the Duramax LLY still going through it's teething phase, a factory warranty would be a big plus.

I think it would be easier to take a Dmax CC truck, cut the body in the middle of the rear seat, and section in the back half of a donor Burb. That is gravy body work and cutting the frame wouldn't be too hard either. The biggest glitch would be to get the rear HVAC and other controls to work if the wiring can't be simply plugged in.

I saw one a while back on Ebay. It was a custom type deal from a place that does this in the Denver area, I believe.

I would add that emissions surely has something to do with no diesel sub.

That doesn't make sense, Ford put's a diesel in the Excusion.

There are all sorts of deals with the emissions nazis.

They make deals about what other cars/trucks you can sell, to what states you can sell them, and how many, etc. Very complicated stuff.

For instance, the EPA might tell GM that they can sell 500 diesel subs in the state of ca, but then they can only sell 2000 gas subs in the state. (When they may very well be selling 5000 gas subs in the state.) Its just an example.

Pry that, and the hassle to get everything in the truck just right is why we dont have any diesel subs.

If you all want a diesel sub soooooo bad, why not get the x?

1. The Excretion is bigger than I want to go;

2. The PSD is not a Duramax;

3. I'm very happy with my gasser Quadrasteer Yukon XL, but I want all the bennies and giggles that come with my GM diesel pick-up.

Personally, I think GM is making a better product, and I use Fords at work exclusively. A few builders have proven that the conversion can be done easily, and the one I've been in contact with says there is no technical reason GM can't produce the D-Max Sub on the current production lines. GM would just have to produce a made to length driveshaft.

I don't know if the Excretion's GVWR puts it into a Utility catagory (or some other catagory) and thus keeps it from being lumped in with the rest of Ford's passenger line-up for emmissions purposes.

Hopefully GM will listen to the requests of their consumer base when the next gen Suburban is released.

1. I wasn't comparing the dmax to a PSD. I was saying that if ford can sell the excursion with a diesel why would the emissions laws be different for a diesel suburban.

2. The Excursion is considered a 1 ton so that may answer question 1.

The laws may not be different. What I was saying is that the EPA does regualte the amount of "gross" emissions that you can put out per state. (thus limiting the amount of emissions Bin 1, 2, etc vehicles you can sell.)

For example....The 2006 Touareg is 50 state emissons avaliable. Why? Because VW sold a whole load of PZEV Jetta 2.0L's in the last year. The Touareg did not change, but the EPA basically cut VWoA a deal.

Do you see what I am saying?

Here's the Fourwheeler article. (http://www.fourwheeler.com/featuredvehicles/129_0407_suburban/)


Here's the guy in Colorado. (http://www.blwilliamsllc.com/duramax.html)

He had a white one available a few weeks ago, 3 inch body lift, used the Suburban front end. The only way you could tell was the badge.

I too wanted a Duramax Suburban. Shopping around and talking to dealers, I also heard of the 5.0 Duramax to be put in the Suburban/Yukon line. The same dealer also told me that the Duramax was in such demand, that to put it in another line would be even harder to keep up with demand. I don't know how much was truth or fiction, so instead of waiting, I ordered a crew cab short bed GMC. I'm happy with my descision and haven't looked back!

I read elsewhere on the forum that the Dmax was going to be cut back to 250 HP and put in the vans w/4L80 trans. If they do it for the vans, why wouldn't they do it for the 'burbs? It would probably get the same mileage as a V6, and they wouldn't have to deal with the balancing issues associated with a V6 such as balance shafts, although it would be somewhat lighter. They better do something. If gas keeps going up, 'burbs are going to be sitting on the car lots.
