Rear Shock Fluid

[Van Voyager]

I notice the KZ1300 manual details a procedure for changing the rear shock fluid - basically: unscrew the air hose, dump the fluid out, completely fill the shock with new fluid, then dump out the specified amount to leave the correct level in the shocks. Not sure if that procedure applies to the Voyager shocks or not- I think they're the same shocks as the KZ/ZN1300. I'm not getting a lot compression-damping (maybe there isn't any???) on my shocks right now and I'm assuming a fluid change - possibly slightly thicker fluid - would help with that. Anybody changed their rear shock fluid?

I do not know if the 1200 and 1300 used the same shocks,but I changed it on my 1200 several years ago,and I really liked what it did for them,then they started leaking.I made the mistake of replacing them with the Progressive 416s,because they were advertised as an air shock,and I was very happy with the VXII 's air shock
The 416 is really a spring shock with possible air assist,but the spring is so stiff it rides like a hardtail,and no air is needed.
I would much rather have new OEM shocks.
The reason I did not use the 412s is they are a high pressure nitrogen gas shock,as are the door and hood struts on our farm equipment,and I do not like the short life they have.The 412s do have spring assist.

I changed the fluid on one of my 1300's a number of years ago.
I used ATF sealer/conditioner and they felt good and never leaked again .
I do not recall the exact amount but if the shocks are completely compressed the level should be just below the air fitting .
DO NOT OVERFILL .
I looked it up. Rear shock capacity is 265 ml

I always drain the shock fluid into a marked container (cc). And only refill with the amount drained. My strong recommendation is to only use any ATF or only synthetic light weight fork oil 10w.

The reason is when cold ATF and synthetic oils flow. On my 1200 I mixed 5w and 10w synthetic fork oil. On my 1700 I used 10w synthetic fork oil. ATF is 5w, but very refined, which makes it a very stable fluid. Also these oils work well in high temperatures.
