Will the rear arm HPG shock off an 97 FIII fit on my 97 MXZ? I think they are the same, but the part numbers are different.

Rocketman: The shock will fit but the calibration will be a bit different. Dino http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/wink.gif

I noticed that is seems alot stiffer than the one I had (when it was working). What calibration are you talking about?

Rocketman: The compression and rebound rates will be different,Skidoo sets them for the application that most likely they will be used in, such as rough trails or lake running. Dino http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/wink.gif

The mxz will have a stiffer shock on it compared to a f3.Same shock body and outer appearance but the f3 shock will be calibrated less stiff than a mxz shock. http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/biggrin.gif

The f3 shock will be calibrated to be softer in the compression but faster in the rebound. *That is a lake racer shock. *Your mxz shock will be calibrated harder and rebound slower giving riders more control in rough stuff.

On a lake bumps can cause serious problems and a stiff shock can dislodge a rider. *That is the reason compression is softer so that the rider and sled hardle feel it. *But rebound is faster allowing for a quick reset of the suspention system.

oh well, its stiffer than the one I have, because that one's pooched. It'll do. Got it used for half the price of new, so can't complain.

rocketman,
*can you not rebuild the original one ?

No Paul...they are "disposable" http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/smile.gif

Just put it on. *You probably wont feel the diffrence.
