I guess it depends on how and where you drive. Mine have 137k miles on them but need changing in the spring.

so it's worth keeping a z55 or z95 suspension vs bilstein on 4 corners? I want to do all 4 corners but if the ride quality is better with the oem then I'll keep it

It's worth keeping your Z55, it helps with handeling plus I notice on windy days, the Z55 soaks up wind gusts. Plus it rides much nicer than standard suspension.

+1 to keeping the OEM system (at least for the GMT900 generation - I don't have any experience with the newer trucks). It's well engineered, durable, and I find it easy to work on on the rare occasions I've needed to, such as changing out the rear shocks and compressor.

Ok, so I'm wanting to replace the OE front struts on my 2012 Denali. I don't have the Z95 rpo code, only the Z55.

The front struts have a connector plugged into the top and I've looked at the Arnott SK2954 and it says it includes a sensor to eliminate dash panel error messages.

Is this the model I need? I'm confused, sone descriptions say it's a conversion shock and that it's a "passive" replacement. It also lists having the 6DA/7DA spring codes, but mine are the 6F1/7F1

Passive means a conventional strut not electronically controlled so for anyone with auto ride it is a conversion to a passive strut. It appears that this is the right pn but I haven’t used them and can’t verify the spring type. Someone that has will chime in.

the only replacement I have found for the front z55 suspension is Monroe 40049 which is in that $300-$350 range. if I remember correctly the AC delco equivalent is about the same price.

this is what is on my truck now

When I looked up for my 14 denali awd.. I got the monroe 40048 w Z55 Susp
and the ACdelco # was 580-434
Hope this helps.. This would be the correct OE replacement... And retain
the factory Z55 active handling. Which is what I'll do when it's time.
I did the rear shocks last summer with the correct ACdelco air ride shocks
