Roughly 4" is the length of a stock CJ shackle. I'd never recommend running
a shackle more than 1" longer than that. 9"+ sounds like a nightmare waiting
to happen.

Nine inches you got to be kidding, you could go into the spring
de-arcing business. Have a picture so I may replace theses ruined

3" is the proper length for a CJ's steering alignment.

You should check with procomp to see what shackles their springs are
designed for. Too short will cause springs to bind and be hard, too
long will allow the springs to over flex and go flat or invert.
