2006 Yukon xl with zw7 suspension

[JCODOHERTY]

ZW7 also calls for particular jounce bump stops in the rear. Usually overlooked these days. The Hummer H2s and Escalades still call them out correctly and have them listed. You'll notice that they're longer than the regular ones. Rock Auto got them to me easy enough and for the right price. Dealers want way too much for them. I have them with GM replacement Nivomats and GM replacement HD/Z71 type springs. Seems to work well enough. As close as original as I can get it for the back. Might be a tad bit high when unloaded but doesn't dance around and the slightly more than factory rake is what I prefer anyway.

I did not know this. Thanks for the information. I found a set on Amazon referencing the GM part #15270578

For my 04 Yukon XL SLT w/ ZW7 and Nivomats it calls for GM part 15115208, same as the Escalades and H2s. Look for made in US stock. World Parts Direct or Rock Auto will have them.

ZW7 & Nivomats here also, but in an '04 Tahoe. I saw #15115208 on Rock Auto with identical diameters and a slightly different (more robust) profile from #15270578. That price difference is substantial. Should I ever need to replace these, your recommendation looks like a firmer upgrade. Thanks again.
