My installer mounted the valves on the outside tabs of the tow bar - well out of the way but very easy to get to.

CheersKevin - sitting here, thinking of there

Mine are directly behind rear wheels near mudflaps. Shorter length of hose so less chance of piercing and also protected from rocks. Only really visible if you know they are there.

They wont work with a 4inch lift, the bags are not long enough.... I tried with my GQ.

You will need to space the bags with something to fit in....

Ramp, I must have missed something. I take it that your loaded vehicle compresses the springs until the polybags begin to take the load? If that is the case,then what is the point of the longer springs? Would not shorter, but stiffer springs the same length of the polys be a better system?

He might want the extra height and travel the four inch spring has to offer. Also, the bags enlarge up and out, so could fill the void, especially if a spacer is used.

Desert,

Shorter, stiffer springs will give a much rougher ride unladen. Polyairs are an excellent solution where load weight vary's and you do not want to go down the progressive spring path and want to maintain ride height.Regds

Yes Tristo, but. He is not going to get anyfurther compression travel because he has put the spacer in with the poly bag. And, down stroke travel is not determined by spring length, rather shocker stroke length.

Ramp,

I put mine inside the car. I drilled two holes through the floor of the Prado in an area that has great protection underneath. Stops dirt and damage to the valves.

Ramp,
I fitted the valves near each end of the aluminium step on the back of the GU. This is a pretty safe location where the valves can't get bashed, and the hose can be secured away from stones, etc.
There is a hole in the chassis behind the step about 20mm in from each end which allows the valve to be fitted thru. To drill the holes in the step, I had to mark the hole position from behind the step thru the chassis hole, remove the step, and drill it while removed. Works well.

On an earlier GQ I had which had longer springs fitted some time after I installed the Polyairs, the installer fitted a rubber block spacer under the air spring. I understood it was a Polyair accessory. But it wasn't a 4" lift, only about 2".

Ramp,
Unsure if this will work on a GU, but on our '90 4Runner, our Polybag valves are mounted just forward of the leading trailing arm bush ( Chassis end ) this keeps the hose length short, keeps them reasonably well protected, and easy to get to.

Ramp,

I have a Discovery and the valves have been located alongside the fuel filler spout, locked away behind the flap and well away from any damage.
