Thanks Kevin1970. It's turning out just the way I envisioned it.

Re: My 52 GMC Build
 

Well I think your only about a 6Hr drive from me. ;) You have a very nice truck

Re: My 52 GMC Build
 

I know it's been a while. I got the box all together and on. Got all the bolt holes for fenders, which was not easy with the truck being so low and no hoist.
Attachment 1381647
This is the front of box side support I made had one of the fender bolts go through it.
Attachment 1381648
Had to cut some of the front of box to clear frame and wires. There will be a bracket to hold front to frame.
Attachment 1381649
Also got the box top tubes welded on turned out very nice.

Re: My 52 GMC Build
 

Time to clean shop out, ready to make running boards. So we pulled the truck out and WOW does it look good. This is the first time EVER I have seen the whole truck. There is no better feeling than seeing what you have built all in one piece out in the sun. Now I really cant wait to finish this and drive it!

Re: My 52 GMC Build
 

Hell yes! That looks sweet man! What do you have planned for the front wheels?

Re: My 52 GMC Build
 

I'm thinking of running the 16" rims that are on it for a while. I'm not putting spacers because I want to keep all that weight under the bearings. Going to get 245 or 255/60/16 tires before I drive it. There is 235/60/16 on it now.

Re: My 52 GMC Build
 

Loving this build. Never thought I would see a dually and think hot rod, but you are nailing it.

Re: My 52 GMC Build
 

Thanks oossuuu754. I'm happy its all coming together

Re: My 52 GMC Build
 

This is a pretty cool idea. 7.3 was a good engine. I used to own a company that built custom diesel trucks. Mostly the 6.4 but the old 7.3's have a huge following. We could get them up to 350hp. More could be had but it all boiled down to how much money the owner wanted to spend.

Re: My 52 GMC Build
 

Wow SSABMUD That's a crazy twin turbo set up!! I'm hoping for 300 hp and 500 lb. Diesel Doctor is close to where I live. They said with my setup I should be able to but we will see.

Re: My 52 GMC Build
 

Got one of my running board frames made today. I used 1.25" tube
Attachment 1382124

Re: My 52 GMC Build
 

Got the running boards finished and welded on. The truck will sit on them when it's all the way down. The frame is 3.5" off the ground, I came straight down from under the frame then out from there. I used 5/16" sst flat head bolts to hold the 3/16" aluminum checker on.

Re: My 52 GMC Build
 

On the second dyno run it made 1076hp with a broken header. If you want to see some videos my ex business partner made of it on YouTube, just search (TheDrsmoke) and it is called the farm truck. It was a custom 2wd (I said to get 4wd) short box we built for racing. Could not hook it up on the track so we made a street truck. Punch it on the highway at 60 and it would go sideways. Ah the good old days.

Re: My 52 GMC Build
 

The running board looks great!

Re: My 52 GMC Build
 

She is looking real good. What will be ride height? Going to be a bear to get a floor jack under. Mine is tough but not as tough as yours.

Re: My 52 GMC Build
 

nice work and vision, dunno how I missed your build. I always wanted to do a diesel build. bags, dually and diesel, you got all the right stuff.

Re: My 52 GMC Build
 

Thanks Dieselwrencher

Re: My 52 GMC Build
 

Thanks SSABMUD At 120psi on the front bags I get about 4" and at 150psi I get 5.5" running board height.

Re: My 52 GMC Build
 

Thanks 99

Re: My 52 GMC Build
 

I'm assuming your running 2600lb bags up front? 150 psi seems high, even with that weight you have up front. You could add a bag cup to make up the height and run a lower psi. easy fix if you feel its too ruff down the road.

looking good out in the light for sure. I like how the dually aspect is almost hidden.

Re: My 52 GMC Build
 

Very cool build Lower50's. Truck looks really good sitting out!

Re: My 52 GMC Build
 

Your bag pressures do seem really high. How big of a bag do you have in there?

Re: My 52 GMC Build
 

Nice!

Re: My 52 GMC Build
 

Thanks guys. I have 2600lb or 6" bags up front and 3055lb or 7" bags in the back. I wasn't really concerned about the pressure I figure 120psi will be my norm. At that pressure my front arms are close to level. But I do have some ideas if it rides like crap. What are typical air pressures in other trucks?

Re: My 52 GMC Build
 

I wish I could be of more help there. As my first bagged ride still hasn't hit the road (though very very soon it will) I'm running sleeves in the back so its gonna differ from your monsters. I feel 2600lb bag up front and sleeves is about 60/40 front to back. I just never hear of guys running over 100psi up front but you might find some info out there where guys are. If you just put a put a cup in there, I think that would help you out alot. I'm running cups top and bottom. I had to angle cut my bottom cup to work with my stock lower control arm. which you prolly won't need to do with yours.

Re: My 52 GMC Build
 

Where are you getting your pressure reading from?

Re: My 52 GMC Build
 

Thanks 99. At 60 psi mine is not even off the ground, but the way I figure it. A 350 is about 550lb dry, my motor is about 1000lb dry. So if your running 60psi I'll need to run about 120psi because I have about double the weight. It all comes down to pounds per square inch, a bigger air bag would give more lift for the same psi. Ride height on my rear bags is around 25psi.

Got some stuff I ordered end of January. My GF's parents brought it home for me last Friday from the states.
S10 big brake conversion kit. It feels like Christmas.

You should find some cool looking old school dually front wheels.... dont need to be chrome or anything.... just 16.5" phat wheels!

Re: My 52 GMC Build
 

Maybe I'll get some 16" steel rims and dually hubcaps. Never thought of that option.;)

Re: My 52 GMC Build
 

I put the order in to local rad shop for my custom radiator today. The core size will be 21"X 24" 4 rows thick (about 3 1/4") That should take care of things. They said it should take about 2 weeks. :metal:

Re: My 52 GMC Build
 

Really diggin your build.

Re: My 52 GMC Build
 

Got my locker installed in the diff today. Also worked on some air leaks on the bag side.
Attachment 1392048
Also here is a size comparison from my Dana 44 out of my jeep. To my Dana 70HD in my GMC. Spider gears, carrier bearings, cross shaft is about 1.25" in dia.

Re: My 52 GMC Build
 

that looks stout, wish I could man up and get a locker. I'm siiiiick of one wheel drive in every vehicle I own.

Re: My 52 GMC Build
 

Nice parts in the D70!

Re: My 52 GMC Build
 

Well last night I just needed to fabricate something, so. I built my trailer hitch. Fit exactly where I wanted it to. 1/4" X 2.5" gussets and 2"X 2"- 1/4" wall tube.
I have a 1/8" gap on bottom of tailgate to receiver. Welded tube and gussets to frame.

Re: My 52 GMC Build
 

nice job. I need to get my hitch on. they are so nice to have. plus i like to run the license plate right between the hitch and tailgate. Though about building one rather than buy. Sux for me cause my gas tank is already in, so don't really want to weld around it. might just have to make it bolt on, which will prolly suck too. I may just drop the tank and weld one in. your gonna be able to pull a house!

Re: My 52 GMC Build
 

Nice work on the hitch!
