Default Air suspension conversoin

I'm wanting to go ahead and do an air suspension conversion to regular struts, and I haven't been able to find a guide anywhere if anyone knows where I can find one. I'm also exploring the different replacement options, and I'm wondering what the verdict is for a good brand for the replacement shocks

If your wanting to do the oem air suspension setup, really not cost effective. Best off going w/ a aftermarket air bag kit.

KYB is an OEM supplier for Toyota/Lexus and is my pick.

You are right, there are very few guides if any. It's fairly straightforward if you have ever done struts. Just know that the air system will throw a light since you removed it and you cannot turn it off by coding.

Is it as simple as removing all the air system components and putting in the reg struts? I've got a mechanic to help me out with it so the labor is no problem. I was more or less wondering if there was a sequence or anything I had to follow while doing the conversion to avoid throwing any codes or causing any electrical problems. I was also looking for a guide for exactly what parts I needed besides the struts themselves that need to be swapped out

Hopefully someone who has done it will chime in.
Electrically it looks like the Air Suspension ECU has stay intact because it it is unhooked or if the Air Sus fuse is pulled you will loose your stop light switch.
Maybe just turn Air Suspension off but leave electronics intact(minus the struts)?




And it's also wired into Skid Control ECU and AFS ECU, etc so more reasons Suspension Control ECU should prob remain intact. IMHO
There will probably be codes but hopefully only seen in Techstream and not error lights in dash that you will see.

Check out strutmasters.com or American air suspension. They sell conversion kits from air to regular. I was looking into that to swap into mine as well.

besides the struts you will need
- all springs, struts, upper strut mounts, strut boots.

you can piece it together but may be more then the whole kit. Or you can find used springs.

I think the kits come with instructions to fool the ECU from throwing errror codes. I didn’t dig deep into that but I would think you would have jump something in the wiring to fool
ECU in thinking the air suspension is still there.

Whats it cost to replace the bad one? vs the whole conversion kit? Be curios to know how the the two suspensions compare.

It was about $950-$1100 for the whole kit

One air strut is about $950.
