Minimum Center Bore size of 14 Bolt FF rear axle - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Getter-Done** · 06-20-2023, 02:16 PM

I am looking to have a spare stock set of Tires and Rims for my 84 C-20.

Currently it has 36 x 10.50 x 16.0 Super Swampers on it.
The center bore is 5 1/8" Diameter on these 10" rims.

I want to get a set of rims 6.5 x 16.0 rims.

I know some of the van and 2wd rims will not fit this axle.

What is the (Factory) center bore Diameter,
I need for a 14-bolt full floating rear axle?

I have a Corporate 10 bolt in the front.

If your getting an aftermarket wheel, don't worry about it, they will fit. Pretty much any 8 lug wheel will fit. Ford/Dodge used bigger hubs than GM, so they will fit. Even 15" will fit lol. Did you have a wheel in mind?

Yeah
This is the closest Example I can find in the link below.

I want this style that will fit over the center housing of the axle bearing hub in the rear.

I could take them off and measure But I am working late for the next few days and thought about going ahead and ordering some that would fit..

Update
After the Storm let up here.
I got a jack and tools.

I went back to my Collection

.

I dug out one of my spare 14 Bolt rear axles.

I took a (Red neck) measure of 116mm /4.57" on the machined surface of center bore.

My goal here is to get a set of rims that I can run what most people call Street tires on this truck.

I got a Tire shop up the road that will mount the tires.

When I look for Aftermarket rims,
All I see is 8" wide rims.

I am looking for the 6.5 like the stock rims.

I may have to go with the aftermarket 8" wide and a tire to match.

Should be able to find some on Craigslist or marketplace. See stockers for sale all the time on either…
