Hey fellas,
It's been a while!
The 85 F350 has left the fleet. I got sick of patching it together....so there's now a 96 F350 4x4 pickup with a 208k mile Stroke, E4OD, and Dana 60 sitting in the driveway. Everything I said I would never own....I now own


But, I'm back to working on the F-Superduty dump truck...and wondering about axle options....
It's a 1991 F-Superduty with a 7.3/ZF5/2wd with a 12' dump on it. I'd like to end up with a maximum capacity 4x4 rig.
Considering the truck probably weighs 8k pounds, with a 6k pound load, plus towing a 8k pound trailer puts me around 22k pounds.
So I've been thinking that maybe some F550 Superduty axles might be the way to go so I can have some 17.5 or 19.5 wheels with some F or G load range tires.

I'd prefer to stick with a kingpin D60 and 10.25 dually axle, but I don't think there are too many heavy duty 8 lug wheel/tire combinations that would work. Anyone else have an opinion about that? I know there are some members who installed a 60/10.25 combo back in the day and worked fine.

Has anyone put much thought into Supeduty axles recently? The Superduty D60/D135 combo sounds pretty good!

How was everyone been!?

 

Personally, i think the current axles in there would do the trick. You can buy 8on 6.5" 17.5 wheels. We have some on our 93 that is our all around ranch / work / fire truck. I forget the exact size but the tired some out to 10" x 33.5" $600 got us the wheels and fresh caps. That is for a SRW tho, but im sure they make them offset as well.

We went to them to get the 14plys to avoid flats, that big **** water tank didnt really get along with E's very well either.

 

I apologize for the confusion! I'm talking about the F-Superduty 2wd truck....not the 96 F350. I edited the original post, because it wasn't very specific at all.

8 x 6.5" 17.5" wheels....hmm....now that sounds like a good combo! I wouldn't hesitate to run a 60/10.25 combo with some 17.5" tires. Thanks buddy, sounds like a good option.

 

I'm also doing a 4x4 conversion on an F-Superduty. The stock D80 axle is plenty stout, and I like the rear discs, but the lack of an E-brake on the axle is an issue. The stock driveline brake works well (on mine...), but I'll lose that with a transfer case install. I'm looking at making an adapter to put the driveline brake on the back of the T-case.
I'm putting a D60 in the front, which brings up another issue: It's nearly impossible to get 10 lug hubs for a D60 that match the pattern on the D80 rear. I'll probably run 8 lugs on the front until I can find/make them.
The F-550 axles sound great. I just can't afford that option.

 

Chevy P30 van wheels come in an 8x6.5 pattern and they are 19.5" wheels, eagle alloy makes an aluminum version with the right hub bore and pattern, the P30 wheels need the hubs machined from the chevy 4.56 to the ford/dodge 4.88, but they are 19.5's, i have a connection to get them so PM me if your interested.
