    Right. That's what I narrowed it down to. The Z71 comes with Gas shocks (black) that look the same as the standard shocks. The standard shocks are oil-filled. The Z71 Appearance Package (chrome tow hooks, Z71 gauge faces, special grille, etc.) gets the upgraded rancho shocks.

    I have a Z71 without the appearance package, but it does have a towing package and it has the all black shocks.

    back in the day, the Z71 package included Bilstiens but not sure any more, if Chevy is getting there shocks from Monroe they could be Rancho's. I thought the Rancho's were made by Monroe.

    look to see if there is any numbers on the shocks that you could google.

    Thanks for the information. It really helps when you provide the codes. That way we can compare to our individual trucks and not guess. :great:

    I agree that that is good information. However, I do think that gm should mention I there that the rancho shocks only come on the z71 appearance package (separate from the z71 suspension package even though the shocks are a suspension part). If they pu all of this info in one area of information, I think it would avoid confusion for people

    Got another question about this. My truck does have the Z71 upgraded appearance package and has the Rancho shocks. I got under to see what model of shocks they are but I didn't see a name or number.

    Anybody got an idea what Rancho model shock they are using from the factory on the 2012 Crew LT Z71 Rancho? I'm wanting to lift my truck and might get the Rancho MyRide kit.

    The newer GM Z71's come with a Cheap Rancho shocks, Not the Bil's that they had before. one more case of GM going CHEAP again.... :( I just got my new Bilstein's and will be putting them on soon. As the Bilstein reps will tell you. After 100K miles if there shock is not leaking it's still good And when I had my 02 Avalanche I changed my Bil's for new ones and they were both the same in damping.. So the old ones were still good..
