Default Toy axle knuckle stud upgrade

I am building a new axle for my yota, was wondering what some of the guys on here that are running toy axles are running for knuckle/steering upgrades, and some reviews on how it has held up pros/cons? 5th stud, 6 shooters, arp studs, 9/16 studs, trunion eliminator, marlins 25mm pins??

I always ran ARP studs from FROR, with Marlin 4 bolt steer arms. I never had any issues with anything loosening or shearing.

1st setup: 36x12.5 SXs on stock axle with 1.5" spacers, lunchbox locker
2nd setupt 385x14.5 SXs on +6" diamond axle, lunchbox locker.

I was going to upgrade to hydro assist, just never got around to adding it before I sold the truck. I'd have considered a 5th stud at that point.

What was your opinion on the trunion eliminator? Would you run it again?

For sure....it was a pain in the ass getting it shimmed right when installing it....not in a difficult way, but in a tedious way....other than that it was awesome. Some people complain it is not smooth and has "sticky" spots when turning but i never noticed it....likely because i had hydro assist which, if you don't have, you need to get running 37's.

I know this is a old post but this just happened with ARP's, Trail Gear arms and stock knuckles. I just pulled the trigger on a set of Six Shooters.

Sheered off the studs and cracked the knuckle in 2 places.

The problem with the arp studs is people don't get or keep them tight enough. It's not a shearing issue, it's a clamping issue. The shearing is a product of them coming loose. Lots of good info here

The 6 shooters are a waste in my eyes. If you get the arp's and keep them tight then add a grade 8 1/2 bolt....something like this



You will be just fine. I and many others have beat this setup silly on 38"+ tires with almost no failures....i have first hand seen the pins on the steering arm (the plus sized Marlin ones) break and the studs be fine.
