Rear Strut Assembly
 

Good afternoon,
I need to replace both rear Struts on my 2006 ES330. I asked the dealer and they gave me a part number;
48530-39885
when I looked at the Lexus online part catalog it looks like taht part number is for the strut without the spring coil?!
Does anybody know, if I could get the whole strut assembly including the spring coil, ready to go?
Does anybody know the part number for that part?

Thank you very much
