ZW7 rear struts for ‘07 Yukon

[mentalattica]

I hope I’m posting in the right place. I have a 2007 Yukon SLT w/ 128k. I rebuilt the entire front end at about 90k. I’ve been nervous to touch the bouncy rear other than the stabilizer links because I kept getting conflicting info on whether or not I have Nivomat self-leveling struts (I don’t know what Nivomats look like to be able to tell the difference).

I’ve come across countless threads about the ZW7 RPO code and how it needs another corresponding code to indicate I have Nivomats. All I see is ZW7 on mine. I was hoping someone more knowledgeable can confirm I don’t have them at a quick glance. I was going to order Delco 540-433 but want to be sure.

This forum has always been extremely helpful so I wanted to also thank everyone!

Post the last 8 digits of your VIN, and @915_Tahoe may be able to get you the correct part number for your truck, and this should answer the question regarding Nimovats.
