I took my rear shock spring off it was an aftermarket spring from Race Tech
TYhe next day when i went to put the STK. spring on I had this extra part ?
According to my Manuals for my 2002 KDX 200 and all the pictures on the web of my exact shock
The Full round ring doesnt go anywhere on my shock !?!
It is the "Full round " Ring under the shock in the picture

(If I understand correctly the Picture of the shock is from an older KDX then mine), But
That part was on my Shock !?!
Should have taken acell phone pic of the darn shock first !
Thanks for any help
Tony
