2002 Yukon ZW7, G69 codes

[geddy2112]

Been reading and reading all the different threads on this site, very informative to the point i am getting a little too confused because of all the different choices people have used and tried.
I am the original owner of my 02 Yukon SLT with the premium auto leveling option. Glove box shows ZW7 and G69. She has 165000 on the clock. She is mechanically sound. The ride is starting to get harsh over bumps lately, especially the front passenger side. I would like to replace the front shocks with factory replacements. Is this the correct shock listed on Amazon? https://www.amazon.com/ACDelco-540-...1&refRID=B5SMN176K3ZFHTYEAN20#customerReviews

My Yukon has towed a open car trailer to the race track and also a boat on some occasions during its life time. I believe the rear shocks are still fine since i recently tow my 21ft boat for some distance. Do most people change all 4 shocks at the same time? Also, While looking under the truck, i noticed that the cone shaped bump stops are falling apart too so i will be replacing those too. Are there any other parts i should swap out during the install?I don't want to compromise the auto leveling by swapping out to other types of setup since she has towed so well in the past. I know the Bilstein swap is popular but that would involve swapping the springs out which can change the way the truck rides while towing.

thanks for the input

Not sure if you have a 4.8 or 5.3 (I don't think it matters for shocks), but just making sure you have seen this to at least know your options.

You say you want to replace with factory shocks, but if there is any chance you want to raise it or lower it, or try to improve your suspension in any way, (for how YOU DRIVE YOUR vehicle), beyond stock; now is the time to AT THE LEAST, look into it.


You don't need to change all four shocks at once if you are keeping the stock setup, but I would at least change the pair (front or back). People get helper bags, or stiffer springs if you are towing often. If you are towing frequently though, keeping the stock setup (if its working great for you) probably is your best option.


As for other parts, it kind of depends on if you are keeping up with maintenance. Do you know what to look for as far as worn out parts, or has a mechanic looked at it recently or made any recommendations?

Are you sure you have RPOs ZW7 AND G69? I've not seen that combination before.

Plug your VIN in here and have a look:

Have your other RPO codes handy in case you find something new too.

This is the picture I took of the glovebox codes. I also have the original window sticker for my truck and it does say premium auto level suspension.

Thanks for the info. I do all the work myself and I will be changing both sides. Not looking to cheap out like that because if u are changing one side, the other side is probably not too far behind. I have a lift in my garage so I do not have to lay under the truck.

Ok, that's what I thought. You have the ZW7 and G65 which are the auto level rear shocks, the nivomats.

So the ACDelco rear shocks are 580-354/12476113 for yours.. and the front appear to be 540-184 but code T2F is not on your RPO sheet. GM Parts Direct shows the front being 12477738.

Rear Springs are 15182555/45H2164.

Yeah, I see C69 and G65 with ZW7
