I just used the RPO decoder and it said the F41 code stood for a firm ride suspension. Does anybody know exactly what parts or options are included in an F41 suspension?

Actually, from what I've read here, and on the history and restoration board, F-41 is the basic, suspension. Then to add, the firmest springs are the Z-28s.

Well damn, I thought I might have something. Oh well, thanks for the info.

 

Sorry to drop your mood, dude. I love it when you find out you've got something good. Well hey, you've got a third gen right!!

 

Contrast to FE1 / Soft Ride suspension.

F41 is sort of a stepped up RS suspension.

Yeah, at least it's a third gen! Well, it's nice to know that my suspension isn't the bottom of the barrel, just close, hehe.

 

Hey i have a question for ya. How about a 1 1/2 sway bar. No one seems to have heard of it. Ive got one and don't know here it came from.

 

1 1/2 inches comes out to 38.1 mm. So it's not a WS6 sway bar. It must be some kind of aftermarket piece, a damn big one! You got me on that one.

 

I have a 1 1/2 inch swaybar also. I have no idea where it came from, and I have measured the diameter over and over with a measuring caliper. I would like to know where It came from!

What is the stamped number on the middle of it. Mine says X189 or XI89, i cant tell if its an I or a 1. mines an 89 irocz, 350 auto. i ran all the rpos and got some that dont read on the rpogram. Im gonna Email chevy to see what tyhe hell this thing is, cause i can't find bushings big enough, and its the last thing i neeeeeeed to install and my winter project is done.

 

Didnt the F41 package include a bigger front sway bar? I believe its 34 mm. Anybody know for sure?

 

Yeah my car's an 89 IROC convertible and I'm sure it has a 1 1/2 sway bar. People say that it's impossible, but I'm totally sure. I'll check that number on the bar later. Oh and my rear sway bar is exactly 1 inch (25 mm?)

 

Its in the middle of the bar. Small stamped letters. I couldn't find any other numbers. My buddy, which is a ford fanatic, says that, when you buy motorsports parts, or high performance parts from ford. The stamping is always started with an X. ?????
I dont know. I think im gonna go bore the 35mm bushings i got to 1.490 to keep them tight and go from there.

 

Well, maybe it's one of those things that Chevy did and didn't bother to let anyone know about it. I've heard of other "mystery parts" showing up on Chevys in the past.

 

Yeah I checked it tonight and there's a number on it, and I'm sure it says X338. I'm pretty sure that's what it says and it's stamped in the middle of the bar. I'm also having trouble with the mounts because there are no 1 1/2 mounts. I think I might buy the biggest mounts and shave them also.
