Full Build: Silverado Short Bed Duramax Sport Truck - SuperMax

Building a big beast of a sport truck is a task full of challenges, but the guys are determined to see it through to an awesome track test! This super 4x4 diesel is going from mild to wild!
We started with a 2003 Chevy 2500HD Silverado and tore it down to a bare frame. Then got to work on the short bed conversion, cutting the frame down piece by piece. After a lot of hard work, we finally had our shorty diesel.
After that, we turned our attention to the engine. We swapped in some new head gaskets and head studs, and then installed an S-366 single turbo kit for some serious punch. The last thing we installed was our beast of a transmission. Engineered to withstand 750 horsepower and sporting a flashy 'Illusion Orange' powder coating, it's built for power and performance.
We've practically reinvented this old workhorse, enhancing its power and performance with a few crucial touch-ups. The next step is to bring the truck out of the shop and really let it rip on the dyno. Stay tuned to see SuperMax in action!

That’s what I love about the 1st gen Ram trucks, the W250 frame is extended at the joining of the rear clip. So shortening the frame to fit a Ramcharger is easy.

[@craigstark2712]

Love the short box conversion! Would have liked to see stage 3 that LT kept talking about, however.

Problem is LT isn't on the show anymore 😕. They go through hosts like underwear. And for some reason think they need 25 projects all at once never really finishing any... not like it used to be that's for sure

Wont happen, bully dog doesn't even make tuners that actually improve power anymore after they got smacked by the EPA. You have to get a 3rd party tuner to do it, or do it yourself. Even then it's HIGHLY restricted.

[@WildNwhEELING]

To be honest, I loved the way it looked in the beginning , minus the front bumper being a mess , but I've always been raised around all sorts of vehicles but in my family it seems when I was a kid the regular or standard cab combination with a long box or long bed was what meant you had a real truck made for hauling , I will agree that when it comes to performance however the short bed will put meanuver on a track setup or on the off road side off things as the wheels become closer together giving you better approach and departure angles as well as getting high centered, but I like the stretched look myself of long bed but hey , to each their own , also IMO resale red icky

Watching the engine tech was interesting. What I learned is I don't have a big enough torque wrench to torque some of the bolts.

[@xkzmxbeastx1]

I get it's for TV. Buys the truck with a S&B cold air intake. Takes it off and replaces it with Bully Dog. Then replaces it again off screen with the final one. Nice!

[@gb1613]

I like how LT pointed out the original wasn't really a cold air intake and then wound up swapping out the real cold air intake for another hot air intake off camera due to the parts sponsorship.

[@Zakkzwrld]

Great build would’ve done few things different though as far as performance. You guys should’ve added keys on the crank that small dowel pin is a major weak point, also you might’ve been able to get a few more gains in stage one and overall if you upgraded the Y bridge to a 3inch the stock one is just as restrictive as the downpipe, one other thing is when trying to push more fuel you could also add higher flow rate injectors and another major upgrade is 2 piece motor mounts keeps it held tight which when your truck pulling you don’t need to rely on a chain to keep it from torquing under load just few things. Anyone with an lb7 should also do wire tuck the stock covering is a major pain… tucking and loosing the OE plastic will save time when pulling 👌

[@damian_adee1669]

Sickkkkk

[@stangbanger93stickshiftonl3]

The factory oil pressure sending unit is a check valve kinda sensor. Oil pressure on a aftermarket gauge wont hurt. But if the stock gauge comes off its starting point it has pressure. And for future searches take a look at LMR, American muscle and cj pony parts. As far as future tuning if you ever decide to change tuners look up Mo’s speed shop out of Dallas Georgia. They are really good with mustangs in general. You can figure the gear ratio by rpm at 55mph with it in 4th o/d locked up. Id turn tcs off at all times, its a early tcs system and it will actually cause you more trouble than it will prevent. It pulls engine timing a ton, and doesnt exactly abs like it needs too in order to help traction. Ive had em sideway and tcs kick in and the car dead hook and go straight in a bad way. Ive even seen tcs activate when its turned off by the button. Could ask the tuner to eliminate it completely if he is capable.

[@imonaroll9502]

They should have installed the non-HD bumper cover to raise the bumper.

[@brianburkett7243]

Im only guessing, but based on all the details you provided... I would bet the first hard yank caused damage at both ends. Whether a visual inspection would have helped or not, who knows. The second pull damaged your recovery point and the soft shackle at the jeep even more...to the point of complete failure. When i saw your video teaser still shot i would have guessed the jeeps recovery point broke and that was the mass and weight that caused so much damage and injury. Thank god that was not the case, or this could have been a complete tragedy for you or your passenger. Thank god you are recovering and learning from this experience. I learned a few things I've assumed and done many times without realizing I've just gotten lucky. First step for me is throwing away my cheap Chinese soft shackles and only keeping my better ones.

So I have a yfz450r I bought unfinished swap with a gsxr750 engine I got it wrapped up but I’m having issues with chain slip or jumping I don’t know. I used the engine mounts they made but asking about engine sprocket alignment with swing arm bolt. Mine is above about an inch or so but it’s dead center with rear sprocket my question is would that cause a problem ? Should I lower the engine to be center with swing arm bolt ? I would be loosing ground clearance but if it’s needs to be that way I guess there’s no way around it. Thank you I await your response.

@joefries365 that's a good point but doesn't the 6.0 put down similar numbers I'm guess not in the 4x4 or awd but in rwd .. its something to look into that's for sure. My 4.3l is starting to get long in the tooth and looking at replacing her soon
