Hi guys an Gals, an hi from over the pond..

I've just fitted some Rancho RS9000's on my truck, they are older in design by the current ones by the looks of it & im a bit baffled with how they work.

There is the compressor that fits under the bonnet (translate- 'hood' ) with 2 outlets. There is a small diameter pipe from each of these outlets, both run to a 6-way splitter. From these, there are 4 more pipes off each leaving me with 8 pipes. Now each damper has only 1 connection so why 8 feeds..?? Is there meant to be some kind of adjustment valves with the kit..??

With regards to how the system works, is it a case of 'soft' when the compressor is not running and 'stiffer' when it is running..??

 

Compressor has two outlets, 1 front, 1 rear. The manifolds at each end have 1 fitting for the air feed from the compressor, one for the left and one for the right shock (and possibly a second set of fittings for dual shocks) and one line that runs up to the in-cab controller/gauge assembly:



Adjuster has a valve to release air out of the front and back manifolds, two gauges for reading the pressure (i.e. stiffness) of each end and a button to run the compressor. Running compressor builds up pressure in the system, making the shocks stiffer. Letting air out of the manifolds softens the shocks.

 

Cheers for the reply dude..

I had an idea it would run something like that, guess im missing some parts then (valves and gauges). I have tried 4 times now to get in touch with Rancho with no success

thanks again for the info and thumbs up for your truck..awesome..!! Nothing like that really over here in the UK. Nowhere to play with em...pesky little Britain

 

Would not be terribly hard to duplicate, the gauges are just simple air gauges, I think they go up to around 100 psi or so for the maximum stiffness. The valves are even simpler, they are just regular tire inflation (schraeder) valves with the bottom over the top to press down on the valve pin to release air.
