I am parting out my car and in that list of parts in my mason-tech air suspension.
This is just the shocks, struts, and bags, not the management and air lines.
Mason-tech fitted universal air bags to bilstein struts. They made all billet cnc aluminum mounts. I made my own rubber molds to prevent metal on metal contact with the frame of the car and the mounts for the bags and such. anyways, this kit is great and is a real jaw dropper. if you want low, this is the kit for you!
I also have a spare rear bag. its brand new and i'll throw it in with this kit.
Below is my build thread.
Almost forgot, they are 3/8" lines.
Price is shipped to the continental 48 states
