I am changing the valving on the front arm shock of my 2003 F7 standard to the F7 sno pro valving. Does anyone know the specs for this change. Any help would be grateful. Thanks.

Simple oil changes won't be enough if he wants to go with the SP style valving. That's really the only way to do it if you need them much stiffer.

I just had the local cat mechanic do my shocks (2003 Standard Suspension). I put them back on the sled and the A arms are nearly horizontal (flat across). I can lift the sled 3-4 inches befor it starts to lift the sled frame! What the ......... Bottoms out with my upper body weight by pushing on the bumper? What now? :dunno:

Maybe they forgot to charge them with nitrogen. That would help a little.

That's what I said to him :dunno: He said they were charged. He told me he would do them again. Is there a different oil other than "cats" shock oil we should try.

The oil wouldn't make it sag like that. Or, what your saying is that you had a lot of sag after they were rebuild, right? If so, did you adjust your springs to the same spot? I know, that's kind of a lame question.

I put the springs back to the same spot as they were prior to the rebuild. The shocks are sagging just as if they were not rebuilt but they felt much stronger prior to installing the springs. I jacked the springs all the way to the top threads and they still had the same amount of sag :dunno: Very soft under load. The sled looks lowered in the front.

hmmmm, that's strange. Did you do any rear suspension changes while the front shocks were getting rebuild. Your rear skid doen't look like it's sitting the stock location. Might be putting more weight on the front end.

Its the firecat in the photo. Notice the flat A arms. This is prior to the rebuild. It is worse now.

The Sno Pro has a resivior. Does this make a difference in the valve stack for a shock without the resivior? Thanks

Best thing to do is remove the shocks and take the springs back off of them. Compress the shock and see if they skip or feel overly soft. They should return nice and smoothly. If the shocks are ok, maybe just add a little more preload. The shocks don't hold the front of the sled up, the springs do. They will help keep the ride in sag just a little higher, but can't really support the weight of the sled. I don't know if I really explained that well enough, ,but I hope you get the jist of what I'm saying. Oil shouldn't make too much of a difference in this. They are probably using stock oil or a lightweight synthetic. I know some guys use straight medium Amsoil shock fluid, but I found it makes the shocks to slow. Too each his own, I guess.
