Outer Limits 4x4 Board

You would want one that goes to about 1800kpa and a decent attached hose that is presure rated to what the reg is rated to plus some But i also had an extra Screw type fitting attached to mine for ease of filling and so the line can be released of pressure after filling. Safety first with such high pressures.

Nitrogen Reg Stainless Steel Diaphragm, 0-400 psi, c/w stemstop for $285.00

yeah roctoy chris. see the trips section for pics .....he didnt have a volume, just said trial and error. and yeah, got access to a regulator and nitrogen cause lee bought one when he got the airshocks in his cruiser

well i took it out yesterday. and the shocks were hard as fawk. on saturday i put in about 60ml of 10w oil (the oil only just flowed back out of the shock when half extended, so it had some in it before), and charged them up to about 1100kpa (160psi). there was about 4 inches of shaft showing

on 'high' speed stuff (drivin tracks at about 20kph) it was like the shocks werent even moving, and the mark on the shaft showed only about 1 inch of movement. so it was very rough

but over slow stuff, the shock seemed to work alright and fully extend/compress

what i'm wondering is, is 10w to heavy for the shocks for speed driving? causing them not to react to bumps at speed? and only working at slow stuff?

i'm gonna pull them off completely this week and refill them from scratch, but any input/experience with higher speeds than crawling would be good

Holly Smokes, thats a tad to much. Explains why it was bumby as hell.

Easy way to think of Air Shocks as springs -

Oil = spring rate (more oil - stiffer springs, less oil softer springs)
Gas = ride height ( more gas - more lift)

So your way to bumpy, de-gas the shock, let out a heap of oil, then re-gas and go from there.

You car weighs different to anything else, so you have to find what works for your rig.

cheers for the reply adrian. didnt think 60ml would have such a dramatic effect on them, from soft and unloading, to solid as a rock.

Yeah, i use a 5ml syringe and even then you can feel the difference. Just remember there isn't a great deal of room in there once as the shaft slides in.

Its a PITA but for you, try stepping up 10ml at a time. Regas and go for a drive. Then come back and do it all again. Let the shocks settle for a few minutes otherwise when you de-gas the shock you will loose quite a bit of emulsified oil with the expelled gas.

well, me an mandy pulled em out tonight to drain them, and drained probably 450 ml out of them

no wonder they were so harsh

There was waay more than that in that one shock , not to mention all the oil that shot into mid air across the workshop a few times

Nearly as harsh as your new Box Shox

If you change the weight of oil do you need to drain the standard oil out then refill?

from what i've read on the bottles of oil. mixing different grades of oils give you an 'in-between' grade. so if ya mixed 5w and 15w, from what i gather, you end up with something in the middle

so yeah, if you want to change up weights, you have to drain out the oil that comes with them
