I have searched Google to exhaustion, and I cannot seem to find the answer to this one seemingly simple question.

I want hub centric wheel spacers, and I need to know the hub bore diameter.

I had my Jeep at the shop and asked the guy to measure the front hubs and he came up with 128.5 mm, which is something like 5.05 inches.

only info I could find in my searches was something like 4.875 inches. That’s a pretty big difference.

anyone have this information?

are the front and rears the same?

I find it annoying that the one thing lacking on the Dana website is a support or contact link. I would have simply called or emailed them directly.

4.785" is correct according to this

Front and rear should be the same, and if they arent then your wheels weren't all hubcentric anyways. Id be less concerned about being hubcentric with an 8 lug vs the factory, but that a personal opinion.

I’m running 40s on beadlocks, looking to go up to 42s, and I actually wheel it pretty hard sometimes (then drive it home hours or days). While it’s probably unlikely to have a catastrophic failure on the studs, with 8 of them, I’d still rather put the load on the hub.

thanks for the info. I sure wish Dana published the information.

now to figure out what my mechanic charged me $50 to measure

No it s 122mm. you can call Dana aftermarket support to confirm.

I don’t know how useful of a thread this might be since these axles really are as close to bolt in as you can get but I figured some little tid bits might still be useful for some. I have a Rock Krawler Long Arm so things are a little in different for me but as mentioned these axles are bolt...

That’s close, but not exactly 4.785.
I would love to call Dana aftermarket. They seem to hide their contact info very well.

The trick is looking at the PDFs:

I will add that ~6 years ago tech support was awesome. I called to get hub bore size before ordering wheels and the guy pulled up the technical drawing for axle and got me what I needed. I called about 6 months ago to get the part number for the bolt that acts as a stop and the experience was not the same...
