how to tell if rear shocks are going bad in ProAction ?

[TrailxRider]

I have an '07 RS Nytro with about 900 miles on it. I've never jumped the sled and all the miles are trail riding. While working on the sled recently it seams like the rear is sagging more. I'm not sure if its just me thinking it looks lower or if there's something wrong with the rear shocks. How can you tell if they need to be redone? I can't ride the sled yet bc of no snow to tell first hand. Any help is appreciated.

My brothers 06 Nytro had 4000+ miles of hard trail riding on it before he got the shocks rebuilt.When you ride it after a shock rebuild the difference is night and day.Before the sled would bottom lightly on the G-out bumps but last winter after the shock service it was alot harder to bottom.Take the rear shocks out and see how hard it is to squeeze together(front one with spring removed),if its shot it will go together with little effort.A rebuild only cost him $50bucks per shock,alot cheaper than new shocks of any kind.

Well shocks do not control the amount of sag only how fast the suspension travels up and down (controlling the spring rate vs weight forces) if it seems diff than last yr you may have eated tooo much turkey.

Seriously you would have to ban the crap out of the sled to change or damage the spring rate in 900 miles.

when I lift the rear up and set it down the sled sinks a little which I know is normal but then if I gently push on the rear I can push the sled right down with little effort and it won't come back up on its own. Seams like there's not a lot of rear travel left. That's why I ask.

and I only weigh 160 lbs haha I work out regularly and slowly gaining weight as muscle mass. I weighed more last year riding.

Well slowly pushing down on the rear has nothing to do with the shock if you take the spring off and compress the shock it won't re-extend itself that is the springs job.

Shocks can sometimes cause the problem you are describing... I would take them out and check them or have them checked and possibly serviced. OEM shocks are notorious for having poor quality fluid to start with and a service can do wonders.
