I took them apart and saw a crappy way of securing the adj. screw to the lifter body. There was a 1/8" hole drilled in the side of the screw with a nylon insert which fell out as I disassembled the lifter. There was no interference fit at all!!
I then put the screw in my vice and "distorted" the threads in a number of different areas. Finally I re-assembled with red locktite. Hope it works, they seem really tight now. I believe JAX has improved on these lifters as mine must have been an early production run... I'm still disappointed, for the price I expected more..
Thanks for the update. Not cheap for sure and you should expect better for that price.

No current price listed that I could find.
