C10 6 lug conversion
« on: May 21, 2021, 12:37:48 PM »
I’ve look into doing a 6 lug conversion on a ‘74 c10 so I can run ‘99 and up 6 lug wheels. It looks like I can do this with out adapters by using front rotors from an early 90’s light duty 2500 and rear axle shafts from a k10. Has any body on here done this swap and how do the stock later model wheels fit? I tried searching but wasn’t coming up with any info.

The logical thing to do would be to run wheel adapters for $150 bucks and be done with it.

I thought about spacers but I wasn’t sure if that would push the factory wheels out to far. Either way will cost me about $150.

Other considerations are bearing size on spindles and rear axles. You can cross reference them online, but I would start there.

Then measure the center line of the wheels you want to use/run against the same of your rotors before and after (using adapters)

If not familiar with the term 'center line' it's the mating surface of your wheel to your rotor/drum.

Measure against the width of the wheel to the rear, or inside. Subtract the inner distance from the overall width of the wheel.

The front inner and outer wheel bearings are the same but I forgot to check the axle bearings. Thanks for the input.

Summit offers a 6 bolt conversion rotor  I used them to run transit wheels everything fit as it should. The 6 lug light duty 90s rotors wouldn't work the caliper wouldn't bolt back up. It's been a few years but I think the rotor was set inward too far

Awesome, thanks for the info. Did you just run spacers in the rear?

I just ran a 4x4 rear end. You can run just the axles too
