I recently helped a buddy of mine put some Rancho RS9000X shocks on his F150 Supercrew. They had adjustment ***** just like the KYB AGX's do. He also bought a kit for under $200 that used compressed air to adjust the shocks from inside the cabin. We screwed off the **** and put a new piece connected to an air hose on. Are there any kits like this available for the AGX shocks so that we can adjust them without getting under the car?

Here is a link to the kit he bought:

I havent seen any shocks like the ones you are talking about for the maxima.

OT: Those shock are awsome, my dad has a set on his lifted 86' F250 I'm always messing with them.

 

The closest thing is the Tein EDFC damping controller, but it only works for their coilovers. I'm pretty sure an application will fit the Max though.
