I have a rear Nitrex track shock absorber off a 2002 Polaris Edge RMK 600. This is a oil filled shock absorber. It has good compression up and down with no leaks. The dust shield does have a cracks on top. The shaft looks good. This shock is not made to rebound on its own, it does not have gas in it. It is just an oil filled shock absorber, non rebuildable. It works as it should. It does not come with the lower shock bushings, you will need to use yours. The lower shock tube does have a small dent, just cosmetic. See all pictures. 


This will fit 2002-2010 Polaris rmk, switchback, sks, trail  600 700 800
