Here's my 2006 Dodge Ram Mega Cab 3500 dually conversion. It was originally set as a 2500, but I changed that up quickly. After I had the dually conversion done, I put in a 6-inch lift with Fox shocks and a remote reservoir with Firestone airbags in the rear. I finished up under the truck with a dual 5-inch turbo back exhaust and put on 6-inch black tips, plus a set of Rock Star dually wheels and wrapped them with 35-inch Toyo tires. Under the hood I put in a new cold air intake, an H&S Mini Maxx and 120hp injectors. I also installed a deep tranny pan from ATS. I then did a little upgrade to the steering and then I started taking care of the cosmetics.
I had the underbody and frame custom painted black, installed a custom grille and front bumper. I also installed some LED head and tail lights. I changed the hood out with a SRT hood with a functional scoop and had the Dodge custom painted black all around. I went ahead and de-badged it, installed a B&W goose next hitch in the bed and put in a Laramie package with custom fenders. Once I got started with everything, it only took me a week to get it all done.
