"08 Z71 Tahoe Oem Struts?

[EddieC]

Looking to replace our original front struts and it seems that conventional and monotube struts are listed by aftermarket manufacturers but I can't find any information on what our Z71 was originally equipped with. Anyone know? We liked the way it rode from the start as GM intended so we're not looking for a significant change.

540-472 front
540-300 rear

So monotube was original on Z71?

One GM parts site notes front #540-573 for a 2008 LT; no specific listing for Z71.

Can you still see a label at the bottom of your strut with the part number?

Those numbers I got were kind of a quick search and after reading it seems that they didn't do too much different on the shocks like they used to on the z71. If yours are black then I assume they probably are the same strut and any LT.

The front struts are red and original. No obvious labels on the struts and the finish is significantly deteriorated. Worth another crawl under there though.
The original window sticker noted Z71 option with "Off Road Suspension".

I did find a press release that noted "high pressure struts".

Only factory ac delco fronts I can find that are red...
540-472
540-579
Take a look at your rpo codes for suspension numbers... should start with a 6 or a 7...

I see 6TJ and 7TJ. How do I use that?

Your part numbers show "monotube" which I have read have "high pressure" so it seems to be adding up. I was considering KBY replacements that come fully assembled and they have a monotube option.

Yours by rpo codes listed would be 540-579...
Rock Auto has them for $83.79...

Thanks for chasing that around.

Thanks for chasing that around.

FYI: Red means Rancho shocks. They were OE supplier for Z71s
