FX-3 ....something I did not know
 

Was not aware that the FX-3 system had six shock valve settings per switch setting....if you were in the performance mode the shocks stiffen more as you go faster.....below 25, 25, 50, 75, 100, and 125...

Re: FX-3 ....something I did not know
 

I didnt know until I read the small drivers book as a part of the MY90-91 pizza box. It speaks to this along with a graph ratio. Neat huh?

Re: FX-3 ....something I did not know
 

I thought the first two settings were really only used in touring...and that the switch settings basically decrease the speeds at which they begin to firm up. Which is why if you are at highway speed and flip the switch around nothing should change at certain speeds, because you are full hard by then. I don't think you need to be at 125mph to be at the hardest setting.

Where is the best place to get them rebuilt these days? I need a set done...

Re: FX-3 ....something I did not know
 

Bilstein still does em. Keep in mind Ron thats all they do... they do not clean them up repaint them or put new stickers on they simply rebuild the internals.

Re: FX-3 ....something I did not know
 

Does anyone know what they charge for rebuilding?

Re: FX-3 ....something I did not know
 

Depends on the valving. They offer standard and morroca valving for the Autocross types.

Re: FX-3 ....something I did not know
 

$100 ea doesn't matter if it is stock or custom valved.

I had mine done something like 20-30% more rebound and 10% more compression. They may have just tested one out on the shock dyno to get close to the appx valving desired, but i have a feeling they have done enough of them to know how to set them up just by giving them the firmness increase desired.

If i had to do it again, I would have put a little more rebound and compression valving in the fronts, but not the rears.

Re: FX-3 ....something I did not know
 

They will rebuild for free with proof of purchase

Re: FX-3 ....something I did not know
 

Phil, you mean to the original owner of the car, right? Or if you buy their FX3 shocks new? TIA

On the FX3 the early cars it does say it the the ZR-1 owner's manual about the 6 selections within each of the three switch positions. Remember the system changes two more times on it's way to becoming the "active handling" system that debuted in the C5. I think the 93 & up cars have an updated version and the 96 cars have a system without the driver controlled FX3 selector switch. I think that is the time line anyway!:o

Re: FX-3 ....something I did not know
 

I think they consider GM the orig purchaser.

If you were to buy new 4 shocks at $200ea, then there is a warranty. Could you imagine if people found out there was a way to get free rebuilds...GM probably bought 200k-300K of these shocks over several years that the option was available- bad business case for sure.

Re: FX-3 ....something I did not know
 

Correct

Re: FX-3 ....something I did not know
 

Hmm used to be more for the morocca valving good info

Re: FX-3 ....something I did not know
 

She will ask for proof of purchase

Re: FX-3 ....something I did not know
 

:thumbsup: So is it correct to assume your leaky shock has been repaired Phil ? Geat info for the club

Re: FX-3 ....something I did not know
 

I had Rippie send off the FX3's on the 89 when the coilovers went on the car. It was 80 per shock plus shipping. If you can still find the FX3 computer this is a good mod as well if you track the car at all. A friend had a 90 track car with this done and it was a noticeable difference in how the shocks reacted. I wanted to do the same with the 89 however I was never able to locate a computer...

Re: FX-3 ....something I did not know
 

You can get 4 new FX-3's from DRM for $450... I thought rebuilds would be a better value...

Re: FX-3 ....something I did not know
 

I wiped my rear shock down to see how fast the leak comes back
I have not sent in my shock yet but Lisa has made the offer to repair it for free, I have a parts lady reciept
She will replace it for free but none to replace it with now
I have another correct rear shock, I wanted to put on car during repair, but the gear is the wrong gear on top, hence, I have not mounted it and sent in leaky one for repair, Those DRM prices seem very cheap, maybe old, or just wanting to clear out C4 stuff

Re: FX-3 ....something I did not know
 

Just got one with a roadrace chip from Lingenfelter, they have a couple other chip options. but haven't installed it yet. I don't know if the 89 would be the same controller.

Re: FX-3 ....something I did not know
 

That's what I think it is. I bought the rear trailing arm relocating brackets from them on sale recently as well.

Re: FX-3 ....something I did not know
 

Holy smokes! That's a little over 1/2 of what I paid for a new set four years ago!

Thanks Mike and Phil for the info. I have to go dig up my receipt for my shocks and drop an e-mail to Ms. Ciacci.

Thanks guys!:thumbsup:

Re: FX-3 ....something I did not know
 

That's $350 for standard shocks and +$450 for FX3 upgrade for a total of $800 to purchase the FX3 shocks. Not that fantastic of a deal.

Re: FX-3 ....something I did not know
 

:o thanks. Now I don't feel like I paid the corvette tax and a ZR-1 tax!

:cheers:

Re: FX-3 ....something I did not know
 

I got a price from my local part supplier last week of $375 per shock. That $450 was looking pretty good but maybe not anymore. Might look into rebuilding as next winters project.

Re: FX-3 ....something I did not know
 

Should be about 200 per shock
try e shocks

Re: FX-3 ....something I did not know
 

Just got a rear pr from e shocks and shipping was free, very good service!

And I found them here on our forum thanks guys, not ready to install yet but
when I do I'll have a few questions...jimmy

Re: FX-3 ....something I did not know
 

I will have to see what they will charge for shipping to Canada. The free shipping is US only.

Re: FX-3 ....something I did not know
 

Bilstein left a message on my phone today. $100 ea to rebuild plus any parts beyond the standard seals and oil. Shipping is on me...

Cheers,
