I have arp hub studs, and knuckle studs. I have broken 3 arp studs, cant say anything about stock, because I never ran em since I upgraded to bigger tires. I would do bobbys dowel mod over the hub studs, more studs is better than stronger ones IMO. Also do the 5th stud, its easy and well worth the piece of mind, if I had done it to my marlin arms, not just my tg ones, maybe this wouldnt have happened
