2006 2500 SRW to DRW conversion

Hey guys, I was just wondering if anyone has heard of someone successfully putting dual rear wheels on their truck. I'm looking for more traction on the pulling track and nothing beats 2 more tires on the ground My main concern is that the axle tubes/shafts are too short on my axle for the dual rims and that they'll rub the leaf springs. I don't want to run spacers because I'm hooking to a 30,000# sled. I'm looking for measurements to compare. I found a used axle dual axle with 700,000 miles that would have to be rebuilt(at least bearings and fluid change) but if I could just use my axle with only 82,000 miles it would save me lots of money I could use for other upgrades

I'm looking for outside edge of one leaf spring to the outside edge of the other(in case springs are different). Also need short side and long side axle tube lengths of a 2006-2009 DRW(maybe back to 2003? not sure if all 3rd gen duallies are the same)

Thanks in advance!

Not sure mounting dual wheels on a single wheel axle is going to work. Call the owner of wheel adapter.com in California and ask him he knows his stuff. He sells a conversion to make an e350 passenger van a dual wheel so it's possible iguess

I poked around his website(this guy is cool!) but his adapter kits involve a spacer and rims...or just an adapter to run dual rims...was afraid of this...

I guess I could swap the tubes, shafts and springs over to my differential to make a wider axle?...maybe...could be fun lol

Thanks for the help!

Why not find a rear end from a dually and install it?

They're hard to find, especially low miles, my truck only has 82,000 miles on it. Most dually axles are open diffs so that they turn, I want to keep my lsd. I'm really not sure what all the physical differences between srw and drw are. The frames might even be narrower, obs fords were that way I know, my fiance's brother ran into that issue when he dualled up his F250, I think he wound up running spacers. I'm just doing research to find out if it's feasible without use of spacers. When sled pulling it puts too much stress on the outer bearing and axle shafts imo, especially if it bounces.

I'll be sure to bring some pictures and lend tips if I go through with this in case anyone else out there is crazy like me lol
