i have a H2 hummer with a 6.0l in it and its AWD, i want a diesel truck but i love my H2. Has any one done or know someone that has done a duramax swap like out of a 4x4 2500HD? i was thinking it would not be that bad of a swap because every thing on an H2 is HD motor and trans mount should be the same and im thinking it will bolt right up. Its the wiring that im not sure about. i know there a gear head on here that can help me out.

The Allison that the Duramax requires is massive in size compared to the 4L80E/M32 transmission you have now. These dimensional restrictions are one of the sole reasons the D/A was never offered in the Suburbans, as the frame rails are too narrow. Your H2 is more Suburban/Tahoe that it is anything else and I think you will have the same problem.

There was a company called www.duramaxsuburban.com that was doing conversions which included a body lift on the to fit the Allision above the frame rails, but I can't get their site to come up.

I use to have a H2 and when I inquired about the conversion it was 60k 4k more than I paid for the H2new!

Just talk to Eric Swanson at duraburb about doing my truck $15,000 to $16,500 out the door that what im going to do.

Is that price with or without the donor vehicle to get all the running gear from??


the duramax is a night and day difference from the 6.0, my last truck was a 6.0, same cab config with a dmax and a edge tuner and the thing is a animal!

Price is with the donor vehicle turn key out the door with a year warranty ...sounds like a deal to me. and if you can find a awesome deal on a donor then the price will go down.
