I have a 2008 Alpine 40' and want to install the in line Super Steer Valves for motion control. Does anyone know what the size of the air lines to the front & back bags. I have spoke with Henderson Line Up and they said I would need one pressure for the front and a stiffer pressure for the rear. Are the air lines size the same to front & back?

Here is an SS-MCU thread with some more info I found using the "FIND" feature, @ top of the Alpine Owner's Forum. Dale tells how to get your line size (outside diameter I presume).

@ Q'zite DRR I spoke to the teenie-bopper at the Hendersen display. He indicated only a need to know line size, and then he'd sell me a kit per axle (they need to be installed in pairs to cover front or rear axle). He didn't say anything about "pressure." But then I'm not sure he had started shaving yet. Hopefully you can elaborate when you get a complete answer, and let us know what it cost for parts & installation & who did the work.

Here is another MCU thread with some photos on pg.2 of Dale's front axle installation, and some good discussion on what's up in the MCU world.

Hello Alpine Road Warrior:

I installed the valves on my 2001 just before leaving for Indio this year. My Alpine used 3/8 inch air lines front & rear. It should be the same for all Alpines.

Where can I buy 3/8" air hose, prob only need less than 2-feet? Any thoughts are helpful? On-line preferably.
