2012 Expedition Limited 4WD - Check Air Suspension Message

[Marc K]

Hello All! I have a 2012 Expedition Limited 4 wheel drive that has the "Check Air Suspension" message and a rear end that looks like a lowered truck. This truck is not my daily driver but I wanted to get opinions - since I need to replace the rear suspension I was trying to figure out options if I also wanted/needed to buy new tires (currently running 275/55/20 on original wheels) also - possibly going with a small lift and larger tires. Any ideas or suggestions. Thanks!

As I work my way around this site, I wanted to confirm that it is (or is not) possible to replace the rear air suspension with springs/coils. If that is accurate, is there a rear suspension set up that is preferred based on the truck not being a daily driver, no towing, no off road; just looking for a more economical fix while also being able to raise the truck a bit to fit larger tires on the stock 20" wheels. Thanks!

Check out this thread.

Which rear air suspension to coil conversion should I purchase for a 2011 Navigator?

Looking for suggestions / past experiences etc. for which air to coil kit should I buy for my 2011 Navigator? How is the air suspension warning system bypasssed with these conversions? It appears that Arnott is the only source that has a bypass module mentioned in the desription. I'd prefer...

One thing nice about the Arnott is:
“Each kit includes Arnott’s unique, engineered Electronic Bypass Module, which seamlessly eliminates dashboard fault codes for a clean installation.”

I see that kit and thanks for the additional option. First thing I notice is that it is considerably more from a price standpoint (Over $300 more). Is the Arnott kit that much better or is the bypass module worth $300?

do have instructions or insight on exactly how to install this bypass module?

Instructions leave a lot to be desired. They have a video and written instructions on their website.
