I don't believe anyone but the most extreme users break 6-shooters with OEM studs. I've never ran them, perhaps someone like
@Cruiserdrew can weigh in on that. In researching big tires with toy axles I jumped ship and went with a Dana 60 in Moonshine. Much better strength for much less cost. I run recentered H1s like
@The Phoenician, but as my wheeling tires, with 42s, and PVC inserts. They're heavy SOBs even without the runflats.
When you break a knuckle stud, it's never just one, and it's catastrophic. Having dealt with broken/ripped out studs on the trail a number of times in other people's trucks, I can confidently say that it's a pain in the balls having to get your truck out of the trails, or home for that matter, when your knuckle won't stay together. Upgrading to ARP studs, regardless of stock knuckles or 6-shooters, is a relatively cheap mod when you consider collateral damage from a stud break, not to mention towing bills.
IMHO, steering critical components, such as knuckle studs, are not a place to pinch pennies, especially when you're pushing the limits of the original design, like we tend to do.
