Rear air suspension sag shortly after turning off

[Buster444]

I have a 2017 rebel with air suspension and now that’s it’s cold the rear sags all the way down and my compressor sounds rough followed by a loud purging noise which never existed till this week. Put pumps back up but I noticed if I leave it in off-road height it don’t sag only on normal and aero it sags after 20 min even during the day any thoughts?

The off road selection could run the compressor more as it is designed to adjust the ride height due to uneven terrain. That may be why it appears to not deflate at all. As for the purging sound, maybe a bad deal or loose hose(?). Did you check all hose connections? Have you put some soapy water on all connection points to look for foaming bubbles?

@tron67j no I haven’t got to the soapy water yet been kinda busy but that’s my next move, but I’m kinda considering just getting an air suspension delete and just run regular shocks and struts but I would like some kings or carli suspension but the delete kits only have a few options that I know of

Do a search in the forum for air suspension and delete process, you're going to find a lot of discussion. Good luck.

From my understanding any suspension system will work, you just need to get front strut mounts. And of course, use a programming tool to change the bcm to think the truck never had air suspension to begin with (otherwise you will get error message on the dash).
