Its not a 60 it is a 70. Thanks for the help

 

nope its a dana 70 lol

 

I've dualled out a few 3/4 tons. It won't handle quite the load as the 1 ton, but it will dual out. If you don't have the bigger studs just drill them out . it won't be quite as wide but wide enough. I've done it on a '90, a '91 a '93 a '97 and a '98. The '98 was a lot more work but everyone said it couldn't be done. It was great. Pics on here somewhere. i have the hubs for the front if you need 'em.

 

wow so your saying i can do it and i wont have to swap rear ends ?

 

You ( WILL ) have to use spacers. here is what i did at first...before i found a duelly rearend.

knocked out the factory studs, replaced them with 9/16ths 5 1/4 long grade 8 fine thread bolts, tack welded them with a cast iron rod, to the inside of the 3/4 tone hubs, made some steel 2 inch spacers that just slid over the bolts, used a set of 03 lug nuts, as they are 9/16ths, and hauled my 4,000 lb truck camper 2,000 miles with no problems, would i do it again, obviously i didn't feel comfortable with it or i would have left it alone, but it did work.

with only 2 inch spacers you can just get a finger between the tire and the springs.

 

If your just wanting it for the looks and not for hauling heavy, just get some 2 1/2 inch spacers off e-bay and a set of duelly wheels and a duelly bed or fenders from arrowcraft, and bingo duelly.

if you use duelly fenders from a 1st gen bed you will need to do some work on them to make them work.

a guy on cummins forum named Redneck express did it to a gas 92 4x4 and used factory duelly fenders and it looks nice.

you guys are alot of help thanks so much

 

I didn't even need spacers on any of mine. They all had the camper packages so they may have had wider rears to begin with. The duals put them at cab and chassis width and they cleared the springs by at least an inch. The '98 required moving the backing plates inward so I could put on the 1 ton drums, but didn't have to do any of that on the1 st gens.

 

If I remember Darwin used 3rd gen wheels on his? If so then thats why he needed the wide spacers, the 3rd gen wheels are offset deeper than the 1st or 2nd gen wheels. I used factory studs, the same ones used on my 92 D350 dually. No drilling needed, knocked out the 1/2" studs and drove in the dually studs, I made about 3/8" spacers out of the face of two old front rotors, slid them on,then wheels from another dodge dually and it works fine. I can get a finger between the sidewall and the u-bolts and also have no worries when loaded pretty heavy. This is done to my 90 which I use for my winter beater plowing and hauling coal but I have towed my gooseneck with the puller and had no issues. (not that it was legal)

 

This is all very interesting, i used the factory 1st gen wheels on the rear, 3rd gen's on the front.

theres no way i could have put duelly wheels on the rear without at least 2 inches of spacer.

i wonder what the difference is in our trucks.

my SRW rear was 53 inches between inside backing plate to the other, the duelly is 60 inches.

does any1 no if the power lok out of my 1993 dana 70 single wheel will fit my 1989 d350 dauly rear end will fit its a dana 70 to
???

 

The Powerlok side gears are almost certainly going to be different. The 89 (nuts and cones retaining axle shafts to hubs) should be 35 spline axle shafts. The 93 (bolts in hubs) should be 32. The rest of the assemblies are the same, and switching side gears is simple when you are doing the inevitible clutch disc refresh.

 

Yeah, I used 1st gen wheels on my first gens. I hauled a 3000lb camper for years with no problems.

 

Dar, I measured mine today, from backing plate to backing plate (not the part of the plate that is recessed) it measures 50 3/4". This is on a 90 W250 with the 6" frame.

 

that is so weard, your rear is 3 inches narrower than mine and you just had to add 3/8th spacer to get duelly wheels to fit, when if everything was the same on both trucks it should have taken 5 inches of spacer.

i wonder if it's like old tractors when they were built if they ran out of the correct bolts they just used what they had layin around.

my truck has the 8 inch frame but i can't imagin that making a difference.

i will crawl under my truck and doo some measuring when i get home, i still have the SRW D70 also, so i will stick the tape one some stuff and see what we come up with.

now this is intriguing.
