Hey guys, I am still trying to figure out which of these control arms is the factory design. The new ones I installed have a different location for the front sway bar than the previously installed control arms (which may or may not be from factory). Moog is saying that the control arms they gave me are the correct part but now I'm trying to figure out if they are wrong or if I have a ZR2 that has non OEM parts on it. Please have a look at the picture and let me know which control arms your ZR2 has.

Thanks everyone!

This is the new Control Arm from Moog. You can see the location of the sway bar link is different.
This is what was one the vehicle as I bought it.

Your originals look just like my non-ZR2 4x4 originals, as in the sway bar mount comes off right at the shock mount.

 

Yes the top one is for a zr2, the other 2 are 2dr s10s. you may not have a zr2. Does it say zr2 on the codes in the glove box? Theres also zr2 stamped in the fenderwells. and check the sticker on the door to see if 31 inch tires where stock.

 

Quite a few of the replacement lower control arms seem to have the sway bar hole in the wrong place. Particularly for the ZR2. Seems some companies are manufacturing the more common one and saying it fits all. Which it does if you remove the sway bar. (not) About the only way to be sure it is the correct one is to take your old one to the parts store with you to compare them.
Or cut the mount off the new one and weld it in the correct location if you can't find one. ZR2 specific parts are getting harder to find every day. Last time I was in a junk yard that had a ZR2 I snagged the center link because it is longer and has the extra hole for the stabilizer. Not available any more.

 

Here are a couple Pics that hopefully clear it up. I do see the ZR2 option in the glove box so hopefully I actually have a ZR2 model. I am left wondering why the hell there would be non ZR2 control arms and a sway bar on here but nothing I can do now. I can just find a used ZR2 sway bar and things should line up properly. I measured my front sway bar and I think it was 42" from the center of each hole.

 

Is this a Canadian Blazer? All ZR2's in the US had 31/10.50/15 tires and the W engine. Yours is the X motor and I've never seen any s-series vehicle with 265/75/15 tires.

 

Yes it is a Canadian Blazer What is the difference between the W and X Engines? Cold weather changes?

 

If memory serves me right the difference from w to X was the upgraded injectors from the poppet style and the removal of the EGR valve which I do believe was introduced in 02'

 

The 265/75/15 tires would make more sense in snow than the 31/10.50/15 which were more of a off road/mud tire.
My mistake on the engine code. I didn't look at the year (2005) on your vin number. The W engine code wasn't available in 05.
