My truck is a 2004 Chevrolet 2500HD Duramax LB7 and I'm the second owner of the truck. It came with a 6-inch lift, Halo headlights with HID's and the stereo system that includes two 12-inch subs. In the past two years I have put in an aFe cold air intake, PPE hot+2 programmer and a 5-inch exhaust. I then blacked it out and put the Rhino Lining body liner down and installed boost, pyro and rail pressure gauges.
Last winter I pulled it apart and put ARP head studs in and some 75hp DDP injectors, along with a BD exhaust manifold to balance the flow and 150gph FASS lift pump. I upsized the rims to 20-inch BMF Novakanes wrapped with Mickey Thompson MTZ 35x12.5R20 and added heavy-duty tow mirrors to it. My truck rides awesome. It's a bit rougher since putting the 20's on, but still a whole lot smoother than a solid axle. I would not trade this truck for anything! You can't help but notice the heads turning when driving it. I am currently working on upgrades to the interior and have future plans for the performance end of things.
