Ok guys, hypothetical question: What could potentially happen if someone over-torqued their rear-shocks during install? I'm talking top and bottom, here. Say...if one didn't have a torque wrench, so they cranked on the wrench until it was "tight"?

 

Um, the one-time-use fastners could break at the worst possable moment.
Over-torquing them is actually worse than undertorquing them
and using some blue LocTite...

Next question...

 

See, I learn something every time I post a question here. *.pdf saved and added to my toolbox.

So, that aside (say, they are not a concern), would there be any detrimental affects to driveability?

 

Um, one shock on one side and non-on the other
transition at high speeds into a corner (when its
most likely to break) and the rear end lean could
throw you into the ditch or oncomming traffic...

Oh, I see the question now...

No detrimental effects. Other than the one above. (not a concern)

The top shock mount might not like being overtorqued
but the lower mount has a steel spacer sleeve that
would probably handle the increased torque value
all the way up to the point of fastner failure.
