71 C10 2wd Center Bore
 

Can someone confirm the correct center bore for my truck? I thought it was 77.8mm. Tried a 1/8” spacer with 3.060 hole and it was too tight. Called Discount Tire and they’re telling me it’s 78.1mm. Maybe I should just solve my issue by tubbing the rear! Thanks!

Huh? Whaaaat?

Wheel center bore for hub centric spacers/wheels.

Re: 71 C10 2wd Center Bore
 

An 1/8 inch spacer doesn’t need to be hub centric.
Can be a little loose.
You guys need to learn metric.

What's metric?:lol: All my measuring devices are inches.

Went and got a new battery for my digital calipers. Apparently my hub is not very cylindrical. I got readings anywhere from 77.4 to 78.04. I suppose I should error on the large size and go with a 78.1, if I can even find one.

I didn't think these were hubcentric. I learn something new every day.

I just put on new 20incher AR's and needed no spacer. the hub hole for the wheel was 3.083 or 78.30mm
i just cleaned up the hubs with a paper flapper wheel before i tried to measure them
measure the inside of your brake drum center hole if that fits then the bore needs to be close to that.

Thanks. Wheels and tires fit great with the static drop. With the conversion to trailing arms and bags I get minor rubbing on the inside left rear wheel well when taking left hand corners. Figured I’d try this route before having the wells tubbed ��

i have not gotten mine on the road yet. I went with a 275/55 -20 with stock height all the way around and hopefully i will not have any problems in the front
