if it's a non sno pro the shocks are not rebuildable.

The shock is replaceable without dropping the skid frame. It is a lot easier that way.

I'll look at it this weekend. I'll pull the shock out & see how the springs react. I'm thinking the shock is sticking. If I lift the rear of the sled then release, it settles about 3". If I push down on it, it stays down until I lift it again (it does go up a bit, but not much).

The comments have been useful. I've never worked on a sled suspension before.

Here is a simple fix. Move your rear arm back one hole on the rails. This will take care of the problem and stiffen up the ride. I started doing that with my 02 800 Cross Country when I bought that brand new. When it was brand new I had the same problem you are having. When I sent my shocks off to Fett Brothers on my 03 900 and had a stage 2 kit done with them, when they sent them back their instruction kit tells you to move the rear arm back also. I promise it will take care of your problem and you wont be un-happy.

Try this first. Raise the rear of the sled. Loosen the track as far as it will go. Loosen the front arm limiter straps adjusters (if you have them) until they sag. Now the shock is limiting the front arm travel but that would not be good and could brake the shock so tighten the limiter straps adjusters until the shock shaft moves in 1/4"". Tighten the front shock spring adjuster so the spring is tight. Adjust track tension and alignment to spec's.When the sled is set back down you will notice (if you did it right) that the front limiter straps are loose and the sled is now sitting up pretty. Moving the rear arm back one hole is a good idea. The reason that you have the rear sag is because everyone tightens the limiter straps for better steering ( use carbides). When the sled comes to a rest it sags because it is being supported mainly by the rear arm sp's. You will also have to make sure that the front of the sled is not sitting to high which will lift the front of the skid up.

It was too cold to pull the shock & check it, but I did discover the track was as tight as a rubber band. I adjusted & aligned it, & much of the suspension sag is gone. Later in the year, when it warms up, I'll pull the rear shock & check it & the springs.

Thanks for all the help.

BTW, I removed the axle bolt from the rear arms (I was going to move it to the rear holes), but the arm assembly wouldn't move. I'm assuming maybe there's a sleeve extending into the skid rail holes. Again, it was too cold to fuss anymore, so I'll get to that later. If someone knows about this, maybe you can enlighten me.

Hey, good to know about the track, as for the rear torque arm - there shouldn't be anything like a sleeve extending into the rails, probably just tension from track/shock/sled weight/etc., I had to use a RUBBER mallet to move mine, I just GENTLY tapped it forward SLOWLY until it aligned, after every things done I just rode again with 600s 700s & 800s and kept up and even beat them in tight turns and winding trail (EVEN A RUSH 800). Good luck! if turns out as good as mine did you'll LOVE IT!!!

before u try anything u might want to consider lowering your front suspention , but start by asking someone to put weight on the front end and at the same time check out your rear suspention resistance u might be suprised

Thanks. I'm glad you said it.
