    Gee, I wonder why'd you need to know that - lol

    I measured my 14 bolt hub itself and it looks like a 4 3/8" is the measurement of the OD of the hub.
    IF a wheel spacer were meade to that measurement, it would show through AROUND the hub because the hole for the wheel is bigger than that.
    If you give me about 30 minutes i'll go take a wheel off and meaure mine.

    I measured the hole in my wheels.
    Wheels are 15x10 8 lug Rock Cralwers (from 4WPW) that I bought a couple years ago.

    They measured right at 5-1/8 (5.125) inches.

    If the hole for the spacer needs to be a little smaller than that for strength, I don't see why 5" wouldn't work. It would only show a little. And of course 5-1/8" would be flush for my wheels but everyone's are a little different I think.

    Aftermarket wheels have a larger center hole. I found this out after I had my dually hubs machined. I believe chevy factory wheels are the smallest of the big 3. I do know that ford wheels have a larger hole (though not as large as the aftermarket wheels that I have checked), don't know what dodge is. The best thing to do would be to find the wheels you want to use and measure them.

    Are you by chance making a 8 to 6 lug adaptor that requires no machining of the hubs?

    if you don't machine the hub then you would have to open the center hole in your rim, if you can do that then you would not have to cut your hubs...
