Yes they are used. I used them for about 2-3 months on my DD. I ended up buying an aussie locker and decided to put all new stuff back in. I keep them as a spare but, it doesn't seem that I need them. ZUK @ gearinstalls.com has done a great job installing the "new" stuff. It's been over a year and doesn't look like I'm gonna need these as spares.
