The 2005 models were using up what factory parts were available at the time, hence the 2wd model. It is like you say though, a rare one. I've only seen one and didn't have the opportunity to check it out closely. I'd be interested if it carried the RPO code for ZR2.

 

There's a thread on here of a member having a 2wd zr2, and did an ls swap... I haven't seen it in a while... wonder if he got anywhere with it...

 

Yes it does have the ZR2 RPO code just like the Blazers. I thought that FX Edition was just a sticker and attached to the seats. I even wondered if the rebel wasn't an aftermarket. The ZR2 with the "highrider" is one stick so definitely factory. But when I ran across this 2004 Jimmy with all the same and it came from a different car lot across the country no way are they anything but factory. That extra one inch of lift has to be as well which I suspect is the "highrider" thing. I sure would like to find out who else has found one of these. Connected to the OBD2 scanner it puts the factory as New Jersey even though the Jimmy was a Canada only vehicle.

 

I thought the ZR had a 2 inch factory lift?

 

The GFX was (and maybe still is?) a factory option trim package available on most GM vehicles. There's a Sierra with the GFX stickers and headrest emblem that lives down the street from me, and I've even seen cars like the Acadia with it.

Not trying to fight or call you out, but all the source information I've seen available on the internet says ZR2 package on both GMC and Chevrolet S-series trucks and SUVs were all a 3" lift with 3.9" wider stance from 1994 though 2005. Here's a couple:

There's also lots of broken links to and from ZR2 forums that have been closed down. If you really wanted to go digging for history, you can find some of that info in the way back machine archives.

 

Yes 3 inch. I measured my Jimmy highrider and ZR2 Blazer before I sold the Blazer and got an extra inch. Same with the 2004 highrider I bought on New Year's. I took my tape and measure the ZR2 parked at the local mall where the guy works and the same. I know the torsional can be adjusted but perhaps there was a reason for adding the "Highrider" to the ZR2 sticker. As for the GFX and Rebel badging it was here that someone said it was likely a dealer promotion. So I guess you confirm they are all GMC options. Thank you.

 

ZR2 is the RPO code for the "higher-wider stance." GMC ZR2's were called "Highrider" where as Chevy's just go by ZR2. The GFX package looks to be something on a few of the later GMC's. I'm not sure what you are not understanding?

 

The Jimmy is also ZR2 and has the same decal as the Blazer. However. only some models have the "Highrider" decal as part of the ZR2 decal and those models also have the "REBEL" decal on the bottom. They also have the fx edition. They either have all or just the ZR2 decal. All have the ZR2 too code. Im not sure what it is about that you are not understanding? They are clearly a seperate version of the GMC ZR2s and factory installed.

 

Here are 2 2004 JMC Jimmy ZR2s a 2005 ZR2 which do not have the additional "Highrider" decal included in the ZR2 factory decal. Nor do the have the "Rebel" decal or the special FX edition badging. It is not just how the "later models" were listed or identified or and alternative to the Blazer ZR2. These are separate and specific factory provided models. Instead of being dismissed by people misrepresenting the "highwider" reference I am looking for actual information anyone might have on what these separate versions of the Jimmy ZR2 are? I have only seen 2004 and 2005 models and only a few.

 

I don't think AjBert and I are trying to dismiss you. We just don't agree with you that your truck is a unique model. We're not experts, but we're certainly enthusiasts. AJBert has been an active participant in this community for more than a decade, and I have owned and have been following and researching information on the S-series trucks since the early 2000's, including on the ZR2 specific forums where a TON of deep dive information was done into the various changes and specifics of the ZR2s from their inception in 1994 through 2004/2005 when the S series was cancelled. I've seen no information anywhere that supports your claim that the Highrider decal on your truck denotes a something mechanically or structurally different about yours vs. other ZR2s. The terms Higher Wider, Highwider, Highrider, etc. were all RPO descriptions available from an RPO printout. The term changed from year to year, and between GM and Chevy, but from all the research I've done there wasn't any actual changes in the underlying ZR2 suspension, and the GM service manuals support that.

I suspect the measured height differences you noticed between your truck and a different one is simply due to suspension sag. The ZR2s (Blazer/Jimmy especially) are very prone to this. A simple measurement to the frame or fender in a parking lot won't tell you anything at all. You'd actually need to make sure that both are at factory suspension specifications for ride height, tire installation, vehicle weight, fuel volume, cargo weight, and a dozen other things that will affect that type of measurement. It's possible that the taller truck even has heavier spring rate torsion bars that aren't as saggy as the other truck. Or maybe they and the leaf springs were replaced at some point.

I did a bit of googling about the GFX package to confirm this. The company's website used to be: http://www.gfxtrucks.com but it appears they are either no longer in business or they have changed their business site because that website is no longer reachable. If you really want to you might could find that site in the wayback machine. I haven't found any other primary sourcse, but there are a number of secondary sources that say that GFX was a CanadianTier 1 GM supplier of dealer up-sell trim options that offered things like sewn badges, carbon fibre trim pieces, custom cluster bezels, custom floor mats, decals, etc. I'm not sure if they sold into the US or not, but their packages were quite common here in Canada.

All that being said, I would love if you were able to find any source information that shows that there are factory mechanical differences about your truck from other ZR2s. If you do find any details, please share them with us.
