Thanks very much!

We're you referriNg to my car or dsrxgoompa's car? I always thought that after the m/c was considered a 31. But I've also heard that u/l's were 31's and non u/l's were 30's. This is something that I always wondered. Ill try to check next time we see each other or maybe if he's reading this he can chime in

Edit: he just said that his said 30 as well. Which throws both of my theories out the door. What is a true ucf31 then?

What size tires is he runing? Do they rub at all?
Did you roll, shave, or modify your fenders or quater panels?
How is your alignment? did you get any different arms or anything to get the alignment back in spec?
Looks good!

I swore mines said 31? But i'll double check it once i get back to my car after work.
My Impression the 31 is the MC version the 04-06 models and the 30's are the 01-03 models.

Now I'm stumped too. I checked my 05 UL this morning and it said UCF30L.

Looks like UCF31 denotes air suspension everywhere except the US. So in the US we all have UCF30's. The L is for left hand drive.

Chrispy is correct.
From all the data I have been able to gather, there are no LS430s for the US market that are true UCF31 (and so marked on the VIN plate).
Other markets distinguish the factory air suspension models (similar to the UL in the US - but perhaps with a different feature set)) by the UCF31 code.
I think this issue is now pretty well resolved, but a counter example would be very interesting.
Thanks to all who checked.
