i'm not running those.. i'm running stock style.. and again i just don't like jamb nuts on a street car.. you can tell me you have 500,000 miles on your car with not issues and thats cool.. me personally i just don't like them..
Your car so do what you like. But the single bolt going through the LCA and straight into the strut rod tube is far more likely to loosen, and if it does it can fall out and immediately cause the strut rod to drop off the LCA.
On the style of adjustable strut rods with jam nuts, if one jam nut loosens nothing happens. The double adjuster is still torqued to the LCA and the other jam nut is tight so the barrel of the strut rod can't turn. If both jam nuts loosen, then the strut rod could change length if the barrel of the tube spun. But in order for the strut rod to come loose it would have to unthread off of the heim or the double male, which would be like a 1/2" or more of threads. And while that was happening, the strut rod would be being pushed backward the same amount. You'd notice that effect on the LCA long before you ran out of threads.
