I am wanting to install Poly Bushings and NEW Ball joints in my '01 Firehawk front end ( Upper and Lower Front control arms ). I want to get a used set and rebuild them so I minimize the down time on my car.

A National used-car part search engine, called Car-Part.com - shows 4 Different suspension options - along with names - for the 4th Gen F-Body:

1) F41 ( Firm )
2) FE7 ( Heavy Duty )
3) FE2 ( No name ? )
4) FE4 ( Special )

Now... I ASSUME these are just options with different sway bars/Spring-rates/shock valving etc.
But.. before I purchase these used Upper and Lower control arms and then rebuild them - Are ALL of these 4 suspension options using the same exact Control arms ?

I gotta' think YES - But I don't want to buy them, rebuild them and THEN find out I got the WRONG ONES !

Thanks for feedback !

 

As far as I'm aware, all of the control arms ( front and back ) are the same. The difference is in the shocks/struts, springs, and sway bars.
