I would definatlly go with the sway aways. I just got mine a few weeks ago and they are very good quality. Bigger shaft than the fox's, chrome finish (you have to pay more for that with the fox's) and also the filler valve for the nitrogen is recessed behing a cap and the fox's are just out in the open. Best place to buy the sway aways is trail gear. $225 each
I know of one person that is running Kings and they are turning out to be a pain in the ass.
The main nut internally that holds everything together is coming loose and backing off causing the seals to take a dump...plus the customer service "guy" is some kid who doesn't know torque specs, oil weight or volume
I saw a pic on a bbs of a strut with a negative spring in it(think top out cusion)...that would be cool.I can't recall the brand but topping out with out the annoying clunk would be nice as well as easier on the shock overall.I have limiting straps but they are set up for pure droop
I had Fox struts on the previous buggy and they were trouble free....my current struts suck.
