Help with struts/shocks (Total Newbie to car)
 

Hello guys, I am completely new to the car scene and would like to start working on my 2011 Sonata. My struts need changing but when I look at the car (pics below), the suspension has a spring around it. All the parts online only have this (second pic). Do I have to buy the spring separately or can someone link me a full strut/shock assembled so I can buy? Thank you
