calling all duramax owners

The early 06 LLY is the exact same setup as the LBZ, just detuned a bit. Lots of people don't know that and you can usually get them a little cheaper. Same truck, just different tuning. The easy way to tell if you don't do the VIN check on an 06 is look at the Allsion logo, the LLY still has the old logo and the LBZ has the new one.

the logo will usually do it, but i have saw a few LLYs with the blue logo.
