6 Lug Hub Bore Diameter?

Post by 66stepside »

I've got 5 and 8 lug rides, but I am looking for the Hub Bore for the 74-91's 6 lug front hub OD for a set of 15x8 rims I am looking to buy. The Hub Bore is the space in the center of the rim that allows the rim to fit over the front locking hubs (among other things).
:?:
The net says 108 mm, which roughly equals 4 1/4". Can anyone verify this measurement? Please.

There is a lip that extends outward at the base of the bearing/hub housing that is 3/8" wider on each side than the hub housing itself. I measured this at 4.75" and that is where my steel wheel inner edge starts.
I recall this set of 15x10"s I bought from Summit being the same part number as the GM 4x4 pickups of the same vintage.

Thanks!

So the rims I am looking at are 3.5"- too small to be of use. The quest continues.

3.5" is for the 88+ IFS GM trucks.

Yep. So my choices are to either bore out a few more MM per wheel, or pony up the cash for the 175.00 ea. rims from one of our vendors. :|

Adam, what style of wheel Are you looking for? 15x8 steel? If so check the chevy military blazers from the 80's. I think the were on those rigs.

Are you looking to run caps ? If not i have a set of 6 lug 16.5 steel wheels i would love to sell.

15x8 K10 wheels are very common. I have them on my J10.

Here's the Chevy version of what I'm looking for:

It's the kind where you can hang the hubcaps on the outer lip.

Here's the standard 5 lug wheel- hubcap mounting is the same:

Is that what you're both running?

Oh, you want a 15x6, 15x6.5 or 15x7 wheel. I am running 15x8's, which never came in that style.

But it should not be hard to find those in just about any junkyard.

The top pic is a 15x8 Chevy that takes the stock hubcap, the lower pic is the hub shot of a 15x6 stock five lug.

I am looking for the 15x8 that takes the stock hubcap- 4x4 15x8 versions are hard to find. I think I'll get the 2wd version and mod it to work o the 4wd hub.

Here's what's on the jeep now:

I actually think the 2wd and 4wd wheels were the same back then. It wasn't until the IFS trucks came out that they changed. Because the center hub area on the rear axle was the same size as the front.

Those look nice. Are the hubcaps attached to the inside of the ring, or the outside?

I'll be checking those out online.
