I was thinking about shortening the wheelbase on my '80 GMC dually and making it a SRW 3500 out of it. Are there any serious roadblocks in that idea?
 
so you want to chop the fame and take a section out? or just go to SRW hubs?
 
Correct, I want to chop the frame and take a section out, then put 1 Ton SRW axles front and back.
 
how much do you want to make out? an do you want to go from a long bed to a short bed or just somthing custom?
 
I was thinking about taking out around 2-1/2' to 4' give or take whatever is needed to safely adjust the springs and shorten it as much as I can. It is a K3500. I am thinking more custom I guess. I want a short flatbed on the back with a ball hitch over the axle (or close to it) for towing a goose neck trailer. The truck will be lifted about 4". It won't have any serious off-road capability as this will mainly be a tow rig that can handle well in the mud and ruts that abound on the way to some trailheads. The trailer will be for towing the Blazer around and hauling hay.

Reading Ryoken's thread on trailers gave me the idea. I saw a crewcab that was shortened and the gooseneck is already on hand. So is the truck but it is short a few axles as I used them in my Blazer build. I will just buy some used SRW 4.10 axles.

I just started reading SweetK30's build thread and it looks like this is doable. My only concern atm is, will putting SRW axles on it cause any problems since it was a Dually to begin with? You know, like in the front. Will the axle be to short, will it still be able to tow okay after I shorten the frame, relocate the springs/axles, etc?

It seems like there shouldn't be any problem but I have never done this and there are ALWAYS problems. LOL
 
Here is an idea that worked for me. I used spacers on the rear axle to space out the rear wheels four inches and used the original wheels set on like the fronts. Never broke in many years and tracks ok. In a pinch I can go back to duals and back to singles again and again and I didn't have to bother the front wheels or mess with hubs, wheel cylinders, parking brake cables, springs,etc,etc.....

Yeah, that could work but my goal is to shorten the frame and make a custom tow vehicle. It won't be a DD. I don't want, or need, a dually any longer. The trailer will take care of any large heavy loads.

I did some thinking last night. The dually front axle has the spacer on the hub and the wheel has four inches or so of backspace. A SRW axle with SRW eight lug wheels should fit fine with no changes in attaching any thing under the frame. Sound reasonable?

The rear should be fine also since the frame isn't changing width, just length. A SRW 1 ton axle should fit fine. It will be a super rough ride without any load but it isn't a DD anyway. I figure it could also sub as an emergency off-road rig if my blazer dies on me.
 
i dont see any major problems. I would move the rear spring hangers forward. use the front holes as the new back holes just like if you were going to run 64s. that should get you 2 1/2 foot or so out back to hack off. you will need to run somthing like 48s in the rear, although i dont know if thats safe. but its the easiest way
