I have been looking into some springs and originally I was going to get Eibach's but now it might be swifts. But, I wanted to know where the Eibach spring is manufactured? This could sway my decision.

 

Eibach springs are made here in Southern California.
Eibachs are very well made and of great quality, however I would choose Swift springs because they generally have less coils in their springs which allows more spring travel.

 

Are Swifts made in the USA?

 

Nevermind, it looks like Japan.

 

Eibach's warehouse is located at Corona, CA
