Re: opinions?

i think that if you pull a fith wheel then you need the dully or if it is a wrecker or dump or what ever then yes you do but if she is just a toy and you dont pull a lot then no you dont just my .02

Re: opinions?

I do that kind of hauling with my 1/2 ton SWB. You shouldn't need the DRW, unless you are exceeding 12k GVW rating.

Re: opinions?

mud man is right you dont need a dully for a fith but i find it to be more stable. if you have a d70 i would use that just fine. i dont see way you would have to find a 14 bolt but i am no expert on rear ends... yet. i have 14 bolts and they work great but would think a d70 is stronger but maybe wrong?

Re: opinions?

I just picked up a 79’ K-30 Cheyenne 4X4 because it was a SRW.

Up here the ranchers & loggers run DRW because they often overload the max load capacity. The first thing they do when they get into deep mud or snow is pull off those outside sets & run SRW, the inner sets track behind the front set/tires with allot less resistance rather than cutting separate ruts like the outers tend to do = better forward motion

Re: opinions?

Understood , I fell into mine.

I got it from a friend who shopped around quite a bit looking for this one. When he found it, it had a cracked head so he put a ZZ3 crate motor in it. Then he went out and bought a 3500 Big Horn Dodge ( ) , the K-30 has been sitting since 2006.

I have 1995 GMC SLE HD-1/2 w/102,000 mi. So I wasn't looking when the K-30 came along.

It allways to be that way

Re: opinions?

I would swap to SRW. I have 2 K30`s both SRW, I`ve had over 2 tons in the bed of my reg cab. I think the D70 rear was a dually only rear. I would swap over to the 14. You don`t really need the front 60 from the sounds of what you are doing. I like the K30 because I haul lots of scrap in it, and it plows in the winter, so I like the beef of the 60. It also makes a diff here on taxes and reg with a DRW, I would need Commercial plates if it were a DRW.

Actually there is quite a bit of difference in strength between the Dana 60 full float and the 14 bolt full float. The 14 bolt being stronger. Everything about the Dana 60 is smaller.

Dana 60 Hypoid offset is only 1.125" The 14 bolt is 1.5"

Dana 60 has a 1.625" pinion dia with a 10 spline or 29 spline
14 Bolt has a 1.75" pinion with 30 spline.

Dana 60 has a 9.75" ring gear diameter
14 Bolt has a 10.5" ring gear diameter.

Dana 60 has a 1.31" diameter axle shaft with either 16 or 30 spline.
14 bolt has a 1.5" diameter axle shaft with a 30 spline.

Dana 60 has a axle tube diameter of 3.125" but wall thickness varies from .250" to .560"
14 bolt has a axle tube diameter of 3.48" but wall thickness varies from .215" to .492"

Dana 60 torque rating is 5500 lbs. for a short duration
14 bolt torque rating is 6242 lbs max.

Dana 60 gross axle weight is 6500 lbs.
14 bolt gross axle weight is 8600 lbs.

Dana 60 maximum recommended tire diameter is 38"
14 bolt maximum recommended tire diameter is 44"

These specs are comparing the Dana 60 full floater to a 14 bolt full floater.

Looking at these same specs,,,the Dana 70 is nearly identical in most every way with the 14 bolt full floater,,,so I wouldn't say the 70 is stronger,,,probably more on equal terms.

Re: opinions?

hummer h1 rims and tires for cheap and they will bolt right up on your dually with no need for spacers

trailworthyfab.com for the stock hummer wheels (i would get the 12 bolt wheels)
100dollarman.com for the Wrangler radials 37x12.50x16.5 - Hummer Tires

just take a look $100 tops for a 37" tire is cheap

Re: opinions?

http://www.extremeaxlesales.com/used...lhubspair.aspx

this is where i got the drw hubs for my srw dana 60 so theres no need to limit yourself on finding just a drw dana 60 the only diffrence is hubs and rotors and the rotors are way cheaper then what your running now lol

the same website may have a dana 60 and idk how much they are you would have to call/email and see. theres no need to pay over 500 for a dana 60 after all its just an axle idk why people think there made of gold

Well,,,since the factory made them this way (I have one) I'm not sure I understand the question.

If you are worried about towing, I can tell you I pull a 28 ft 10,000 lbs enclosed trailer (not a 5th wheel) all the time with mine (accross country) and it pulls very nice, very stable. I always use a distribution hitch of course,,,and I keep "E" load range tires on it. For a single rear wheel 1 ton,,,,it's a very nice tow machine. Wheel base is long enough for a nice stable ride.

I bought the single wheel 1 ton purposely because I liked the manuverability in tighter spaces, easier to fit in the garage, and I don't have to buy an extra pair of tires that cost nearly $200 a piece.
It's a 1 ton truck in every way,,,just doesn't have another set of tires.

If I ever replace this truck again,,,,the only thing I'd change is getting a 3+3 for the extra seating space, and the longer wheel base would ride even better.
