How do I determine which hub hole diameter I need? (4.63 or 4.83?)

Bart Hinder · Feb 10, 2019

I'm looking at the Power Stop K2023-36 kit.
For a 2004 GMC Yukon XL 2500 4x4 without Quadrasteer.
How do I know if I need the 4.63 or 4.83 hub hole diameter?
Do I just need to pull the wheel and measure it?

Thanks!

Still looking for an answer to this. Anybody?

yes But measure the hub not the wheel as they don’t always have the same measurements

I was about to say to get a caliper. But there's almost a 1/4" difference in the sizes so you should easily be able to determine which you have. It's always good to have a caliper on hand, anyway. I have a cheap digital one from Harbor Freight that has suited me just fine.

Thanks guys!

Would I ever need to use a caliper to measure the calipers?
Interesting. Same word, different meaning.
Probably the same Latin root.

I guess about the only thing you may ever use a measuring caliper on the brake caliper would be to measure the piston and/or bore diameters if you were rebuilding them.

I see the caliper (measuring tool) having similarities in operation to a brake caliper, so maybe.
