Okay, when I see vehicles driving around, I look at the stickers on the sides. So far, this is what I have gathered:

Ford's FX4 = Chevy's Z71 = Dodge's TRX4

With that said, what does Z28(which I've seen on Camaros) and Z66(Avalanche) stand for?

Thanks.

 

As with z71 and fx4...they are order codes for packages from the factory.

 

more direct answer z66 is a suspension package like z71

and z28 is a performance package. also see ws6 on transam.

 

the Chevy "Z" was/is simply the code for some sort of special package. It's been used since the 60's on everything from trucks to Vette's.

KC-10 FE out...

 

Snip for a gm site...


In the meantime the bureaucratic workings at Chevrolet had already assigned a Regular Production Option code to what they were calling the Special Performance Package. Apparently, RPO Z27 had been assigned to the SS although it didn't appear under that option until 1969, and the new option was assigned the next number, Z28. It is not known when the decision was made to use the RPO code for the name, but probably not until after the first cars were built.

 

I don't have the full description for each, but basically here's what they mean.
Z28 was a performance package on the camaro. This meant more back when they first came out back in the 60's and early 70's. I believe it also included some body hardware...different tires/wheels. In the last generation of camaro....before they became extinct...Z28 was the only camaro with a V-8 which was a 5.7L. If it wasn't a Z28 it had a V-6. There was also an SS camaro during the last few years which had a little bit more power, and unique styling package.

The Z66 package on the Avalanche is an On-road package. I know it includes a load leveling suspension, but other than that I don't know. If you care to research it further go here...www.chevyavalanchefanclub.com.

 

Yep. I have a 30th anniversary ss in my garage with around 9000 miles on it.

 

Do you have a picture of it? One of my buddies has one thats white with red racing strips. Im not positive that its the 30 antiversary but its pretty damn nice. SS package and all.

 

Actually I don't. I need to start it up this weekend and move it around some. I will grab a few then for ya. I just drove it in 97 when I got it, and it has been garaged ever since. I was kinda thinking it may be worth something one day.

 

If it has white leather than it has the 30th Aniv Package on it. The stripes should be orange though. All 97s have 30th Aniv logos on the dash.

Red Lariat if you ever want to sell yours I would be seriously interested...thats exactly the kind of car I am looking for. I want a low mile, original. Is yours a 6spd or an auto?

Here are a few of the rarer F-Bodies I have had over the years:

My 88 GTA Trans Am:


My 98 Camaro SS


My 00 WS6 Convertible (one of 174 made):

 

Mine is the auto. If I had bought it, it would have been a 6 speed. But my dad got it for me for graduation in 97.

 

Hey ram,

Here is an old video of my ss. Its black, auto, ttops. From some info I had a few years ago it was 1 of 126 of that type.

Pay no mind to my buddy laughin when the tires squeal towards the end.
