Would you run these axles?

For sure RED loctite if I go with the screw in studs. The holes left in the pictures are 7/16" and had OEM studs already installed. That's where the knurl marks came from. I punched them out before the pictures.
So IF I go with the screw in studs, which I'm leaning that direction, should I get the 2" or 3" long ones? Will 3" be too long if I use the closed acorn lug nuts after it's all done?
I had the same question when I replaced my studs. The only way to know would be to thread one of your acorn nuts on a stud and measure (obviously you want a bit of space left so you are actually tightening the wheel down and not bottoming out). You will need to measure the thickness of your wheel so that you know how much will be protruding. Plan on 1-1-1/2 times the diameter of the stud for thread engagement (the more the better). You may find you will have to trim a little off of them and if you do, be sure to not overheat them during any grinding process. Harbor freight has great deals on dial calipers. I would recommend the non-digital analog dial type because their digital ones (unless they improved them) do not turn themselves off and the battery will be dead in no time. Good luck
