Hey everyone, first post here and owner of my first Lexus.

I have an '04 RX330 that came equipped with air suspension but the previous owner swapped it for a Strutmaster conversion kit. I don't like the ride quality of the eibach spring/strut combo and the rears are starting to go out (clunking noise/rough ride)

I was wondering if I can switch the rears for a stock coil/spring setup that came with the non-air RX330. When I go to look up part #'s for a stock coil/spring setup I'm getting 3 different #'s for each side:
Rear Left:
48540-0E020
48540-48170
48540-48180
Rear Right:
48530-0E020
48530-48170
48530-48180

Do you guys know if these are interchangeable parts? Can I use any one of these on my RX330 that came originally with the air ride? I've tried calling 6 Lexus dealerships around my house none of them will give me a straight answer and some of them were down right rude... Salvage part places aren't much help either

Would really appreciate your guys' input. Thanks!

I just helped a buddy swap out his air suspension for a regular one. His air suspension died. he went aftermarket, strutmasters.

I would just call a dealership or go in person. the only difference is you need to do something with the air suspension sensors at each corner (the wiring will just dangle).

It took time, but it was a straight forward swap, strutmasters had comprehensive directions.

Thanks but Idk if u read my whole post. I do have Strutmasters right now and I hate the ride quality, it's too bumpy and there's lots of vibration. The eibach springs are too sporty for my taste and doesn't feel like a luxury ride like Lexus intended for the RX

I called many dealerships and even walked into a couple, they never give me a straight answer and the only thing they are providing me is part #'s for the stock air suspension that came with the vehicle which I don't want because it's too damn expensive!

I just want to know if I can buy salvaged stock non-air strut/coils from any RX 330 and bolt them into mine

Posting in case others find this useful.

My front passenger side (air suspension) went out 2? years ago. I replaced it. A couple of weeks ago my drivers side went out (same problem, strut bearing) and I opted to go the salvage yard route. Purchased a 2006 driver and passenger side for $80/each off eBay. Direct fit, plugged the air tubes in the cowl. No error lights and the ride is great - negligible (if any) difference between the air and non-air struts.
