Newbie with a question here-

I'm looking at two trucks, both GMC Duramax's. One's an 02 with 103k miles, the other is an 03 with 127k miles. Were there any changes/improvements done between these years, not just to the LB7, but the to truck itself too? Any recommendations or things to look for on these two?

Thanks in advance. This is a great site... lots of good info.

first off welcome to the DTD forum..the earlier duramax known as the LB7 had some injecter trouble but gm extended the warranty to 7years/200k miles on the 01 and 02 LB7 injecters so thats taken care of but i hear little trouble from the 03 and 04 LB7 duramax so witht that said i would probalily lean towards the 03 verse the 02..good luck

03 has the 7 yr/ 200,000 mile injector warranty too. I think about the only thing that changed between the 02 and 03 is the radio...you don't have a code to put into the radio for the theftlock. It is automatically reconized by the truck from the BCM.
