(stock shock of mxz) Trying to figure out of my rear shock is bad (not the coil over). When I compress the shock by hand it is very hard to compress and then when I let go it shoots back up so fast that I cant pull my hand off of it. Should I be able to watch the shaft move somewhat slowly back to full extension or do they rebound really really fast?
That means they are good. Remember, they are HPG's...High Pressure Gas.

I guess for me that doesn't make sense. I appreciate your response, but Ill explain why. The purpose of a shock is to slow down the springs compression and rebound to make for a smoother ride. With the way that the shock is now it would slow the compression but it would accelerate the rebound. I understand that the shock is high pressure but that just means that it takes a lot of force to change the shocks direction. I have been around racing my whole life and we use high pressure gas shocks all the time when the track dries out, but you can still have a slow rebounding high pressure shock. Anyone elses thoughts?
seems like you got all the answers..... just remember a sleds track is considerably more weight than your hand...or a motocross tire....hence.... more weight + more pressure = rebounds that are proper....remember the rebound is what sets up the next compression...therefore eating the bumps up and not jarring your spine from your rear....
mike, not quite sure why you are taking offense to what I said by telling me I have all the answers. I have been on several forums trying to decide what is right and I have about 50/50 on what people have told me. What I was referring to in racing is a stock car. Weighs 3300 lbs not a dirtbike. Not only that, I told smallengine that I appreciated his thoughts and just explained what I thought and I was looking for more opinions.
who took offense....read your statement and walla...you have all the answers...with one misconception...the spring is to absorb or slow down the shock allowing for comfort on the rebound and a better ride....hence thats why you adjust spring tension when adjusting the shock for more or less pressure...heres a link

Well I just talked to a mechanic at my closest ski doo dealer. The shock is in fact shot. It should rebound somewhat slowly. Unfortunately, they don't have the equipment to rebuild them and cannot order replacements anymore from skidoo. Anyone know of any replacement shocks that will work for this sled (99 mxz 600 121 in skid)? If so could you direct me to an online site that sells them. Or if anyone knows of a place in Iowa that rebuilds them or if it is quite a lot cheaper to rebuild I could ship them anywhere. Any suggestions? Thanks in advance.
Would also consider rebuilding or replacing the coil over shock depending on the price.
Thanks Mike and to all who have given help. Snownstunt, that is exactly what the sled is riding like. It is beating me to death. I have gotten some good places that rebuild pretty cheap off of this and other forums. Ill post a new thread after I have them rebuilt to let people know if I would recommend where I get them rebuilt at. Seems like people are always needing that service. Thanks again.
