I have a 92 F-250 2wd over 8500 GVW, and I have come across a set of rotors and dually adapters off a 89-91(not sure exactly) F-350, I looked up some of the bearings on autozones website and they have the same part numbers listed for a 92 F-250 over 8500 and the F-350, so my question is, will these adapter work with my spindles, and is there anything i'm missing to keep this from working on my truck?
Thanks in advance guys

 

You are taking FRONT, right?

Yes they will go right on.

Rear is a differnt story

 

Yea its the front, so the spindles are the same, just the rotors are different as long as i have the 8600+ GVW right? and the adapter is attached to the dually style rotor?

 

If you are gonna do the rear dually too, rethink the conversion. The frame needs to be given attention on that one.

 

I already have a Dana 70HD dually rear-end under the truck, the frame is just fine

 

Ah I see. I thought you were using the Sterling. Different story.

 

the sterling and dana axles have the same mounts, they are interchangable, I took a sterling out and put a dana in

 

Well from my experience, I took a dually sterling and tried to put it into a truck that wasn't a dually originally, and realized that the frame on the dually truck was more narrow than the regular truck.

 

then you had the cab and chassis axle which is designed for a 34 inch frame width, regular duallys and 3/4 tons are 37 inches wide, roughly. the 34 is a commercial design so it can be adapted to any number of commercial beds like service beds, flatbeds etc.

 

so I heard that the caliper mount is different, any insight on this?

 

Depending on the year.

87ish-94 is a pin on style caliper
95/96/97 is a bolt on caliper and 1/2 bigger rotors
