Well, there has been alot of talk about this and after 1,100 miles it happened. I pulled in of the lake and parked the sled and noticed the the arm was hitting the blocks and the flap was on the ground. I picked the ass end up and it droped to the ground like a brick. I thought the springs were shoot so I turned the blocks from the lowest ( I weight 160lbs) to the highest ( cheap pieces of shit ) well it made no improvement. I thought now I need to replace the springs on my dime. OK Then! This is the strange part which I noticed while unloading from my trailer the day before as well. When I moved my sled by hand to turn it around to a flat surface the suspension then worked like it never happened. Full travel with no built in sag, which is complete bullshit. I did notice that before I moved my sled, it was not flat on the ground, the sled was tilting forward and a slight pressure was aplied to the front arm. Hmmmm!

Could this be just a weak spring ?
Could this be a factor of suspension design and shocks or both ?
Is there a recall on the springs yet ?

This is one of the great mysteries of life which use '02 ZR riders have been struggling with.
No word to date on any rear spring/shock recall or bulletin although a local dealers has been advised by AC the one is in the works but it's content is unknown at this time.

Uneven ground will cause what you experienced. If the suspension is okay on flat ground, then you don't have a problem. I can't explain the why. Put a 4 X 4 board under the track near the rear, and you will swear your suspension is broken, as the suspension will push up and down with no effort. Take out the board and it will be fine.

My 01 Sno Pro did the same thing. It was that air got into the lines of the shocks, cold it was ok, but when heated up it failed. It has the Cross-Link, but I would have to guess a shock or both need to be rebuilt. Got mine rebuilt and it is as good as new!

This true... I use shop dollies to move my ZR9 around... when I put the rear one under the middle of the track, the rear suspension will compress to a point very easily. Did it brand new, 0 miles. Its just part of the design. I know a few Polaris sleds do the same.

I had the same problem not only with the 9 but also with my 99 zr600. I really noticed it after I was hitting the bumps HARD. I would stop and the rear was dragging the ground, it seamed to stiffen up if I let it go for a bit. I had the dealer install a heavier set of rear springs and I had the rear shocks worked on. I weight a healthy 250lbs and I hit it pretty hard at times. No complaints so far, but I think that the suspension would have a bit to say if it could :D
