Suspension problem or normal? - Snowmobile Forum: Your #1 Snowmobile Forum

My 2000 Z 370 rear suspension may or may not have a problem depending on what you folks can tell me.
with the sled sitting on the floor (with nobody sitting on it) the suspension seems to be at a reasonable height but if I lift up on the rear bumper with very little effort the suspension will go up another 4 inches or so. Soon as I let it go it drops back down. I have the springs set at the highest setting.
Is this normal? Do they just do that? BTW my brothers 2004 F6 does the same thing.

Its suppose to do that, I talked to a local dealer and heres what I came up with.
The rear suspension is designed to have sag built in, so when the butt end of the sled gets lifted on the trails or where ever, it keeps the rear track connected to the ground, enabling you to maintain speed, and control of your sled. I thought it was a very interesting theory.

they all do it, my brand new 0 miles 600 switchback does it along with my fusion and supersport.

Yep, that way when you hit a hole the suspenssion will drop instead of the whole sled!

That is known as the kick back relief distance.
Kick back is the amount of over travel that the skid does when responding to bumps.

Thanks all... Good to know.

Mine does that on my 98 vmax, BUT when you let it back down, you can only push it down about 1 inch when sitting. If you sit on it it will not rebound at all when you get off of it. Therefore I am putting new suspension in the rear end.....
