Looking for larger wheel studs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My '69 C2500 has 8-lugs & many of you might think that is enough strength. But, I have it in my head that 1/2" thick studs just aren't strong enough. I've been looking at other 3/4-ton trucks in order to see if they have larger studs that will fit into the current axles. The 1/2" studs have a smaller knurl size than any truck I've checked with thicker studs. I've been looking for 9/16" wheels studs, but they obviously won't fit in the 1/2" stud holes. So, other than swapping axles, does anyone have any good ideas? Part of this question revolves around you 3/4-ton owners who have to use spacers/adapters to run newer wheels on your trucks.

One option might be to drill the hubs for 9/16 studs with the closest size to your hub now. You will have to redrill your wheels too. Is this a 2wd truck now? I'm curious why you think the 1/2" studs are not good enough now? They worked on the truck since 1969.

From my experience, smaller studs have been more prone to problems. I think I have one that may be cross threaded anyhow. And I'll tell you now, I'm fully capable of messing up even the easiest task. So drilling out the current holes makes me nervous. And the wheels will be fine. I'll be using wheels that fit newer model trucks that already have larger studs.
