Since one of the adjuster knobs got ripped off on the weekend , tossing up wether to turn them upside down or not. They are on the rear of an 80 series, at the moment the knob faces inwards, and there is very little room between the disc backing plate and the shock to just turn the bottom 1/2 around.
Has anybody had any problems running them upside down...by this i mean shaft damage??

the RS9000X's wont work real well upside down, if at all
the old RS9000 can still operate upside down so it depends on which shocker you are running

From what I understand from research, the none of the 9000's will work upside down effectively. The valving in the head of the shock is not totally immersed in the oil when upside down, therefore changing the effectiveness of the damping ability.
On a leaf spring rig you might not notice it due to interleaf friction, but on slowhilux's 80 (being coils) it would be quite noticable, like 2 settings different.
Richard showed me a 9012 he cut open, and showed me a line which runs from one end of the shock to other and apprently auto alliance told him this was so the shock will work upside down, i would turn em around, not sure about 9000X's richard runs these upside down as well

My front Rancho 9000s are mounted upside down.
This is the only way this particular model number fit in the front of an IFS hilux (stud on the end with the knob and eye on the shaft end).
Ive been running them this way for a couple of years now and they are still working great.
I had heard that when run upside down they can get air pockets in them which gives a bit of free play but when I pulled one off the other day it was as good as new.
The knobs are $5 each from auto alliance. I've ripped off a few (damaged them on the trail, not stolen them) and I keep some knobs in the truck to replace on the trail. 10 second job.
I ran a pair upside-down once, and after a few days the truck was bouncing all over the place, took one off and cycled it by hand, and there was about 100mm free play before any damping started. Turned them back up the right way and cycled them a few times and they came good again.
This was an old pair I bought 2nd hand though, so maybe they have changed the design since..
I'm thinking about trying some of the 5000 series ones, at 120 each for a 14" travel shock I can live without the adjustability wank..
There is an Old Man Emu shock built for the front of a jeep cherokee that is 12.8" travel which would probably be a good way to go..

If this isn't proof - then what is. I did the same but I had mine upside down for a few months before changing them around. The only reason that Rancho say that they can be mounted upside down is otherwise there would be some vehicle applications where they would not be able to supply a shock. I've seen a copy of an email that someone from this board sent to Rancho in US regarding the matter and they said that it was ok to run them upside down but you must pull the shocks regularly to turn them right side up and cycle them manually to regain dampening effectiveness. Who would do ever do that?
I've got RS99012X in front and RS99036X in rear. I wish that I still had the $$$ and I would have spent it more wisely if I needed to do it again.
You can see my shock mounted upside down in my avatar but I went to the effort of building new shock hoops just so that I could mount them the correct direction.
