Hello, not sure if they came as standard or you could tick an options list, some of them have an external unit stuck to the shock leg, about the size of a red bull can, best of googling it brings up loads of images.
You can buy a complete replacement kit from pedders inc tops springs & struts or you can buy separate springs and shocks
Mr b is your man on here, have a look in the forester sub section as a member has just changed his for normal shocks/springs, there's a thread with various options and part no's
