All valid points. I have the Suspension maxx keys, which come with a bump stop, that stops the upper control arms downward travel, to limit down travel by one inch, which helps avoid binding the ball joints and over extending the shocks. The kit comes with front shock extenders, but the threads on them are different from my shocks threads. I did not use them for that reason. So far, in a year of driving on my set up, no issues from the front shocks. I did use the rear extenders. I do not know this, but, Larry might sell just the bump stops for the upper control arms seperately if you call him. Just a thought.
