OK, so not much progress on my dilemma. Looks like my air compressor may have died - ran for a little while, but springs did not inflate at all. Going to get the truck in the air this weekend (finally) and get a look. I contacted Suncore, and they are no longer making their spring conversion kit - apparently they were having issues with the spring rates. Have not had much luck finding a set of used springs either. Local salvage yards don't seem to have any, and all the searches on eBay turn up springs from 2004 and prior models that indicate that they won't work in my 2006 - why I have no idea - it is virtually identical. And I also saw where someone installed a set of junkyard springs and found out that they were not heavy enough. So not I don't know what the hell to do. If my air springs are not leaking / blown out I am tempted to try to install a schraeder valve to allow me to manually inflate the springs. I can't seem to locate the correct coil springs without forking out a buttload of money to a dealer. I'm open to suggestions. It would seem like I should be able to find SOME kind of spring that will work in this damned truck!

rear 100 springs should work fine with a little lift... Think its 2" I have a contact that has a few if you want I can shoot you his info. https://www.toyteclifts.com/sq-00rc-rear-2-5-lift-coils-for-00-07-sequoia.html if you want new. https://www.1stgenoffroad.com/store/p25/2862Spring.html#/ you'll need the "spring hollow" for the coil spring to seat in https://parts.findlaytoyotaflagstaff.net/oem-parts/toyota-spring-insulator-483130c020 should be out the door under $500 all new parts, cheaper if you find a part out with the hollows for cheap

Update on my situation. I found the online service manual, and ran a straight 12V right to the compressor. It kicked on, so I know my compressor is not fried. But the springs were not inflating at all, and I could hear air flowing. I pulled the springs back out and tested them individually on the bench with compressed air. First one worked fine, second one - nothing. On further inspection, I found that the locating pin on the bottom had busted off. Not sure if it was a defect or if it got cocked out of position somehow. Hopefully I can get something done under warranty with Unity. In the meantime, I tested both of my original springs with air and soapy water, and found that only one of them appeared to be leaking. Just for added measure, I coated the dry rotted area of the good one with black silicone - I figured it couldn't hurt. Reinstalled both springs, and again - nothing from the compressor. So I gave up for the night. I was planning to straight wire the compressor again to test it, and almost on a whim last night I hit the key, and the compressor fired right up and inflated the springs. I am wondering if the ECU tripped a code to prevent the compressor from firing up, and reset itself after enough time had passed.

I'm going to see if it holds for a few days before driving it. Fingers crossed! Thanks for all the help!

I had a similar issue with the air ride on my 2007 crapping out. I sourced 4wd towing springs from a 2005 on ebay. Seller threw in the isolators for free and it was shipped to the house for $200. It wasn't too hard to install and now this thing rides so much smoother than even when the air bags did work. I will say that the blinking dash light is still annoying but the fact that it's my wife's kid cruiser it works out fine, she doesn't notice blinking dash lights...ever.
