Z51 package identification
 

I have researched all the RPO codes to my '89 and I don't show the Z51 or the FX3 package according to the codes. My interest is this, I wrecked the car about 9 yrs ago and the shop took quite a long time to repair due to delays. The shop manager told me that it was more difficult getting some of the Z51 parts? Now either he was using this as a line just for being late or could my car have these items? Is there a way to easily determine if the car has the Z51 package? Something short of a micrometer on a swaybar or something. Just want to solve the mystery so I know where I'm starting from, with any potential mods. This is the only C4 I've owned so I don't know if the susspension is Z51 or standard.

There were many parts to Z51 that were orderable seperately instead of ordering the entire Z51 package. Perhaps he means some of those?

Some of them...

B4P Radiator Boost Fan
FG3 Delco-Bilstein Shock Absorbers
KC4 Cooling System, Engine Oil
V01 Radiator, Heavy Duty, VAR I

Z51 is basically tougher springs, tougher shocks, different sway bars, and what scorp already listed

another option, but unrelated to your problem, is the rear gears. Not sure if your year had a gear for Z51 like mine does, mine has 3.07

And quick steering ratio, power steering cooler, 9.5" wheels all, and better mufflers.

Well,

From the replies I can say I have the following:

3.07 gears
Radiator Boost Fan
17x9.5 Aluminum Styled Wheel

But no codes point to the susspension related items. Maybe I can find a part number on the shocks as they would be different on the Z51. I have some codes I can't place:

A58,BGR,E52,E9Z,MP8,MX0,V73

All other codes are accounted for.
