Yes, I have the z55 primary code. I cross checked GMpartsdirect and the 20842472 part number lines up. Thanks again

I found a match by searching the list of suspension codes listed on the R/A list against the ones in the glovebox door.
Eventually I got a match on just one.

GM got it right on the z55 in this Gen. If the ride isn’t already amazing enough, towing is even better in an XL with the 6.2L on e85. It’s simplicity by today’s standards and strangely budget priced for its longevity and warranty.

Please send me these links as well if you can, as im looking for the same thing for my 2008 yukon slt. Needs front struts bad and would like to keep the factory autoride, Dealerships near me have been saying they haven't had those in years

@petethepug, is there an AC Delco fully assembled front strut for the z55 suspension? If not, is it worth the trouble to buy all the AC Delco pieces and assemble them? How is the full assembled Dorman strut?
@usdlawstudent , what did you decide on? I need the same struts you were seeking.

I still haven’t decided, but going full OEM is going to be like $2k+ out the door, which is pretty steep for me considering the age/value of the vehicle. Rock auto has a passive fully assembled front strut assembly and passive rear shocks for ~$170 each or a little over $750 out the door. I’m leaning towards those for budget reasons. And I appreciate that I’d unfortunately lose the autoride functionality.

There’s no fully loaded OEM strut for the 07-14 z55 / z95 anymore.
Worth it’s weight in gold to buy the OEM parts a la carte. On a few boots and goodies I did MOOG & aftermarket. MOOG has replacement springs on R/A right now. Your current springs should be ok. Save them as they’re NLA if you don’t like the MOOG.
Dorman assemblies were having frequent returns for leaks since introduced.

in case helpful, the arnott assembly is part # SK2954, $197.79 each on rock auto. Lowest price I found anywhere (even taking into account shipping cost). As I mentioned before, we’d lose the autoride functionaloty with these.
Rock auto is showing a Dorman assembly (949650XD) that is labeled “improved design.” Cost is $530.79 each. Much more expensive than the arnortt, but it looks like it retains the autoride functionality. They may cost similar to the OEM DIY assembly and may not be as good of quality or reliability.
