Bilstein manufactures high quality parts. I've read that Bilstein manufactured for Dodge and depending on options chosen.
I would guess that they are standard on your "Last Call."
It's too early here for me to get confirmation right now. Usually there will be someone who knows for sure.
They have manufacturing plants in 6 different Countries.
Headquarters Ennepetal Germany, United Kingdom, USA, Romania, Mexico
And in your Country Shanghai China
