    Just wondering if there grade 5 or 8. I sheared one off and was going to put a new one in and noticed that as I was getting a little ramy installing the new bolt I bent it. /forums/images/graemlins/confused.gif I am now thinking that I'll just use a grade 8 bolt instead of a regular center pin bolt. I'm using ORD zero rates with a 1 inch offset so I don't need the pin part since its recessed. Anyone have any Idea's? /forums/images/graemlins/thinking.gif

    Well after seeing my center pins that came with my springs basically rotted away after only 6 months I went with Grade 8 Allen head cap screws in the black oxide finish. Won't rust and uber strong /forums/images/graemlins/thumb.gif

    The o.e.m.'s are grade 5 or less, [shear bolt]

    I have upgraded, to 5/8" grade 8 center bolt's front, and rear.

    Bored spring hole's, and turned down the head's of 5/8" bolt's to do this. /forums/images/graemlins/grin.gif
