My question  -  is this a part that will wear over a short period of
time, or have I got other problems? Fontis -
  You've hit on something that I feel is an inferior design. I replaced my
original "screen door" springs with the "rat trap" springs about two years
ago. I had excellent free fall and overcenter link snap with the original
springs, both on the jackstand and at 100 mph IAS. After installing them, the
rat trap springs were clearly more anemic and so was the main gear free fall.
Except for some slight aesthetic gain, this is not an improvement. I don't
feel the screen door springs look too bad. Needless to say, I removed the rat
trap springs and deposited them in the trash can.
