2008 Dodge Ram 3500 - Bad Mega

Not your average Dodge

On the short list of many Cummins fanatics is the ownership of a longbed Mega Cab Dodge. The reason these trucks are so desirable is simple: Dodge never made them.
However, that didn't keep enthusiasts from building them, with companies like Longhorn Conversions willing to convert a regular Mega Cab pickup into a stretched-out version of itself. This particular truck was mostly stock, save for the conversion, when current owner Brad Reyes got ahold of it. His plan was to use it as the ultimate tow rig—something that could haul anything and everything.
That plan was cut short when the stock 68RFE transmission made a quick exit on its second trip towing a three-car trailer. With no choice but to forge ahead, Brad decided his truck would be better suited to towing duty with a manual, and he swapped in a G56 transmission, complete with a South Bend 3250 dual-disc clutch.

Since the rest of the driveline was so beefy, it was time to make some power. The 6.7L Cummins engine would see extreme towing duty, so it was immediately upgraded with a set of ARP 625 studs, and the head was fire-ringed by Brown's Diesel out of Riverdale, California. Brown's Diesel also did the tuning on the truck with a custom EFILive tune by Erick Brown. The final step to reliable power production was to install a 64.5mm Super B Special turbocharger from BD Diesel Performance. While the combination sounds simple, it makes a surprising amount of power at 550 hp and an estimated 1,200 lb-ft of torque.
While big power and torque numbers were great for show, the truck still had to do what it was designed to do, which is tow heavy. After seeing Brad's Dodge gross 25,000 pounds up a 6 percent grade at 70 mph and watching the boost gauge sweep past 40 psi with the EGT never breaking 1,300 degrees, we'd say his Ram backs up its power numbers with an immense amount of utility. With plenty of interior space, room in the bed for an auxiliary fuel tank, and a hopped-up 6.7L Cummins, Brad might just have built the ultimate tow rig.
