Yes - i'll probably get drummed out of the JK fratenity for even suggesting that cheap could be a real option.
I'm not suggesting that they are FOX, ELKA or Bilstein substitutes, but then again most people don't need such mega shocks let alone afford them.
I've run Pedders ( in desperation on another vehicle - failed first trip ) OME... which really didn't suit my driving, Poly Performance whiich I had no issues with - except they were too short ( ok... short is relative ) and really wanted something a bit longer for my application.
An i know what you mean re damage - I've killed a shock by so badly dinting it ed that it failed and another with pretty impressive scrape marks, all rears.....
The standard Maxflex coils were available, no issue there - i just needed som springs with pretty specific compressed and open lengths to avoid the little SOB's falling out again
