Well acrually, my Suburban is a half-ton 2 wheel drive.
Amd I'm thining if either getting a kit just for looks, while on the other hand I'm thinking not just for look but also tow capacity just in case I will tow something a little larger.
But what do you think?
Honestly, being a half-ton, I wouldn't even consider doing it. Literally everything in the suspension is different.
You'd be better off finding a rusted out 1-ton dually, pulling the entire body off, and setting your Suburban body on the frame.

The Twister is a 4x4, BUT... If you want to do this on a 2WD VERY CHEAP it will be pretty simple.
Find a rearend / Donor out of an old beater 70's Dodge or Chev motorhome (Should be a similar Dana)
You will need the wheels / brakes / shocks / ...
Dually fenders might cost you more than a used rear end assembly, hopefully there is a VOLUME source in TX or SD, since the cowboys tend to tear them off at the 'drive-in liquor store'
My plan for my 2000 GMC Suburban 2500/454 is to install the dually kit I'm been shopping, fenders, adapters, wheels.
I've pulled trailers with duallys, and they seem to be more stable at highway speeds. The Burb does fine with my 7000 camper, so I know and don't expect to increase capabilities of the truck, just the look and stability for long trips. Also for the look, a cowl induction hood. The truck is black, and the black ones I've seen are just plain mean looking.
So to start let's go over the why would you question for the other guys. One it does slightly change the gvwr. Two is that by upgrading to a heavier duty spring eliminates sag under load as well as increasing stability. Adding another set of tires increases over all WID h and contact area thereby increasing not only traction but stability at higher speeds
So it's actually not bad. I had the chance to go over a conversion last weekend. It's just a matter of leaf springs, I measured the springs on my suburban and my c3500 and they were the same length. Next you'll need a drw axle. With some searching you can pick these up for $100-150 at some junkyards. Obviously get the wheels while you at it. The final piece is the fenders. You cannot use the OEM Chevy fenders. That said the fenders will be the most expensive piece at approximately $400 a pop. I also want to add that if starting with a k platform you'll need to reheat one of the axles. My k1500 suburban is equipped with 3.42s while my c3500 runs a 4.56
I have a 1990 GMC Suburban and I want to know how much will it pcost to convert it to a dually. Along with a pair a dually fenders.
You'd probably have to sell both double-wide trailers.
