Re: She's a ton of fun (dually build on air)
 

This is why I love this board! I like the idea of longer arms and single wheel hubs instead of that long space between the bearings and the hub flange. Not to mention the unsprung weight of that one-ton hub!

Lo, when you say "the stock set-up won't work"---do you mean with the semi wheels (like the pic, and like Rus will use)? In other words; mine is a '72 C20, I will run stock 16" steel one-ton wheels, shorter-than-stock tires (IDK the height yet), stock subframe, PB lengthened arms & bags, & C20 or C30 SW hubs. If I (I mean Nate) get the hub-to-hub dimension right, I should be good to go, huh? I know it won't lay frame, but at a lowish ride height, it will prob be driveable, or will it?

Hope I didnt get off into hijack territory Rus, but like you, I love it when I find a man who knows!

You might be ok with 16" wheels.
The PB arms are for the guys spending the CA$H to run semi wheels, and lay frame.
In your case,... I would just run dually hubs and stock a-arms with bags and cups.
There are ton's of pics on the internet.
I know people use this forum to answer specific questions,... but if you look around, you can find the exact truck you are building.

Yeah I need to give him a call tomorrow. I am actually looking at a set of wheels tomorrow. I hope to be able to do a mock up on paper as in... knowing the wheel offset, thickness of the 8to10 lug adapter and the track width with from hub to hub vs the width from inside of fender to inside of fender. Hopefully I can get it close. Who knows maybe I'll talk to Nate and he will know exactly what I should do! Thanks for your help Keith!
The 3500 came in the half tons and the 4500 came in the 3/4-1 tons. If I understand correctly the 4500 has a granny gear and I'm not really looking for that so I want to go with the 3500. If I pull anything it won't be much so I think it will serve me well!

Re: She's a ton of fun (dually build on air)
 

I could be mistaken, but I think the 3500 has the granny first gear as well (I think they are both 5.34 or something crazy like that)

Re: She's a ton of fun (dually build on air)
 

I'm not 100% on the granny gear thing thats just what I was told. Once I have my suspension down I'll really start to look into it.

GM Specs:

NV3500 gears:

1___2___3____4___5___R
3.49 2.16 1.40 1.00 0.73 3.55

NV 4500 gears:
1______________________2____3___4___5___R
6.34 (1993) 5.61 (1994 on) 3.44 1.71 1.00 0.73 6.34 (1993) 5.61 (1994 on)

Towing with a NV3500 is going to be hard on the clutch if you are decently heavy. I have an NV4500 going into my 1970 GMC. I plan to tow with it so I wanted the deeper first gear to get 20k worth of steel rolling off the light. :lol: Ideally a NV5600 is what I wanted because it has better gear splits and I have towed with one a lot and love this trans. 1st 5.63 2nd 3.38 3rd 2.04 4th 1.39 5th 1.00 6th 0.73 R 5.63 But they are super spendy. Still better than an SM465. IMO

Project is looking good!

Re: She's a ton of fun (dually build on air)
 

Awesome info. I know hauling with a 465 is hell. Going up hills you might as well forget going anything over 30mph. You may hit 40 depending on your rear end gears.

Re: She's a ton of fun (dually build on air)
 

My '03 GMC has a NV3500 from the factory. I've read its good in its stock form for about 300-350 hp. I'm not sure what you have in store under the hood, but something to keep in mind.

Re: She's a ton of fun (dually build on air)
 

Thank you for the info and the complement!

Yeah that's plenty for me, I'm keeping the 292!

292!292!292!

Re: She's a ton of fun (dually build on air)
 

UPDATE!!

I talked to the Porterbuilt fellas today and the plan is to run 1 ton spindles with the stock length arms. After the added length of the 10 lug adapter minus the monster offset of my 22" semi wheels, they should then squeeze up inside the fenders!!


I bought 4 of them today!! Hoot Hoot!:metal:

Re: She's a ton of fun (dually build on air)
 

Sweeeet!!!!!!!!!!!!!!!!!!!!! Gonna paint them? Or keep them like that?

Re: She's a ton of fun (dually build on air)
 

undecided at the moment.

Re: She's a ton of fun (dually build on air)
 

I never even thought about paint! Is that even an option? They would look tough all shined up, too, though!

Re: She's a ton of fun (dually build on air)
 

could be but i know a guy that powder coats too :) Not sure how much he charges though

Re: She's a ton of fun (dually build on air)
 

Those semi wheels look sexy just sitting there!

Re: She's a ton of fun (dually build on air)
 

Pic for you below!!
Why thank you!

Re: She's a ton of fun (dually build on air)
 

Powdercoat those bad boys white!!! Should be around $50 a wheel.

Re: She's a ton of fun (dually build on air)
 

I like having options!

Re: She's a ton of fun (dually build on air)
 

Is that your tire size, too?

Re: She's a ton of fun (dually build on air)
 

Should be close to that

Re: She's a ton of fun (dually build on air)
 

Those wheels look awesome Rusbuilt, this truck is going to be sweet dropmembered on those Semi wheels

Thanks Keith! I appreciate that!

Re: She's a ton of fun (dually build on air)
 

Less than 28" tire height, 4.10 gear, 292 torque---I'm cool with a 3.49 first gear!

Re: She's a ton of fun (dually build on air)
 

Is your PB stuff going to be here by March 16? ;) No reason, just asking.
