14SF "tech" info
Didn't ever really come across any posts with a compilation of 14SF tech info. I copied this out of the other post I made, since the old title isn't accurate anymore. This basically is everything I've learned thus far in my 10 bolt to 14SF swap. Hope this info will help people out in the future...

I used a 14bsf from an 8 lug 4x4 91 suburban, bolt in. I had a 1/2" steel spacer made to mount the brake backing plates so I could use the ( new alloy) 6 lug axle shafts (1/2"" longer) for a 94 suburban 4x4. The brake parts are all 94 suburban 4x4. The axle width now matches the front. I used 1/2" lugs from an 03-04 jeep tj to do away with the 14mm...perfect fit. The fronts I left 7/16.
Edit: I went from 12b to 14bsf, had to shorten the driveshaft 1/2". Napa conversion ujoint.
If I can do it, anybody can.

are there concerns about dropping down from 14mm to 1/2 inch studs? did you order the axles undrilled and drill for the smaller studs?
or how do they not loosen up over time if they are smaller than the original 14mm studs?
There is a 1/2" stud for the 14SF application so you can match front to rear.
Anything is upgrade over our 6lug 7/16 tiny things .
so that is some kind of custom item?
bigger splined area to fit the axle flange, with smaller threaded stud?
if I recall correctly, when I did mine, I already had 4 inch lift springs... with the 10 bolt, the rear driveshaft had slid out of the slip yoke on the transfer case a little farther than its stock location. never had any issues, but after putting the 14sf into the truck, the driveshaft shifted forward back into the stock location -was almost perfect! (therefor I soon afterward put a SYE on the transfer case and changed EVERYTHING!)
I used 1/2" to avoid the pinch fit wheel mentioned in Jason's post. Lug nuts fit correctly. I don't do anything hard-core. Stock alloy axles the studs fit perfectly and still tight 6-7 years.

I’m still wondering if that mention of “pinch fit” is regarding the lug nuts that came with some of the cast aluminum wheels? They have a flat flange instead of the taper… probably for aluminum wheels that were hub centric and did not have steel inserts where the lug nuts go…
They lug nuts on my 9.5 are tapered and fit in the stock steel rally wheels - either the way they are supposed to, or so close that I haven’t been able to create a problem in the last 10-12 years
Dorman 610-475 is the part number for the 14SF 6-lug application.
I will probably go with disc brakes in the rear. Will these work?
I’m still waiting for my wheels to show up. 17x8 wheels. Would like to used closed lug nuts
just out of curiosity; if you are still waiting on the wheels why don't you cancel that order and go 8 lug and swap outers on the front to 8 lug?
My understanding is that doing the spacer for longer axles is not possible to convert to disc. I've been rwong before.
My guess is that the 1/2” wheel studs were for the GMT400 2WD ultra light duty 2500’s with the narrow six lug 14B-S/F while the 4WD versions along with the K1500 1/2-Tons with the bigger rear brake package option (that included the six lug 14B-S/F) all got the bigger 14mm studs and just shared a common hole size in the flange.
Could be wrong but it seems logical and has shown to be true on all the ones that I have seen and worked on.

Ah ha… interesting. I’ll need to keep this in mind for future stuff!
I'll add the lug part #'s to the other thread, to be clear, 610-192 works in the front, 610-475 then is the rear?
That is correct.
