I have a 2001 GMC Sierra 2500 HD truck with a crew cab. It has been driven for 334,000 kilometers. The lb7 engine has a recently replaced transmission with only 120 kilometers of use. I'm selling it because I want to get a Cummins engine or take a different approach. I initially planned to customize the truck but didn't go through with it. If you want more information, please message me. I'm asking for $8,500, but the price is negotiable.
