I was told that when installing the AGX it was important to not allow the piston to spin. What happens if it does? Mine did a few turns on the left rear.

 

The piston can spin, it doesn't hurt the shock at all.
You have to rotate it to line up the notch in the front upper mounts.
It also rotates every time you turn your steering wheel, the strut body rotates as your front wheels turn. Who told you not to rotate the poston?

 

yea that was definetly some giberish that was told to you. dont believe all of what you hear, unless its hear on the org!!!!!
