Summit 6 to 5 lug axles.
 

I tryed some local shops to redrill my 6 lug axles. Nobody wants to do it. My parts guy told me it's due to liabililty. I ordered conversion axles from summit. Since I am getting axles might as well get a locker also. So I ordered locker and the same time tryed to get a wheel studs. Summit didn't know what studs to get. They told me to call superior axles and order studs with them. I called and order from them. Studs arived today and these are wrong studs. I called summit and ripped them a new one. What's got me going is that the tech told me to drill out a new axles so the studs will fit. I'll try to see if local parts guy will find something to fit tomorrow. My truck been apart now for 2 weeks now. So beware of summit axles.

Cannot be to hard, go to an auto parts store and try a few different sizes. im betting if summit sent you to superior that they built the axles

Superior will hear from me first thing tomorrow morning. It's a superior axles but they don't know what studs to run.
Unless this is a stock part that they can look up in their computers my local parts stores are useless.

If you are going to a 5 lug setup from a 6 lug, IIRC the 5 lug studs are 1/2" threads, unlike the 6 lug studs, which are 7/16".

My bet is if you ask for studs for a '73-'78 (not sure if they went to metric later) C10, those should be the correct ones.

:agree:.. with Mike. I would go to the local parts store and get one stud for a '73 1/2 ton and see how it fits.
