    Default Suburban ZW7 "Nivomat" Suspension

    Anyone else looking at replacement rear shocks, (actually suspension supportive dampeners) for their Suburban/Tahoe/GMC with ZW7 "Nivomat" option?
    So far, I found these:
    http://www.shockwarehouse.com/site/p...rucks-and-SUVs

    The front shocks in a ZW7 system can be replaced by good quality gas shocks, but the rears cannot; because the springs in the rear are weaker/softer than normal, and will sag if used in conjunction with a standard shock absorber.
    A spring change (to standard suspension) will allow you to use a regular shock absorber, however, GM claims the ride comfort will suffer.
    BTW: the suspension option should be listed on the inside of the glove-box, hence if You have a ZW7 code (Premium Smooth Ride), or a Z55 code (Auto-Ride Control), it's gonna cost You to replace the dampening units.

    Please post a link if You find the same or similar item at a better price.
    KYB, Sachs, and Monroe builds the above "Nivomat" replacement parts, with the Sachs being the factory originals.

    Here's another replacement part: Monroes for $269.10...scroll down to the Monroe for Nivomat.

    I actually found the factory correct pair of Nivomat shocks (Sachs) on amazon.com for less money than the Monroe or KYB units, and I paid no sales tax, plus received free overnight shipping.

    It sure pays to look around the internet!

    Not sure but mine says LT with autoride right underneath. Not sure if mine is a a Z55 I'm not sure how to find the RPO list and what is on my truck.


    Nevermind found the RPO plate, Autoride is Z55.

    Thought so.
    Auto-Ride uses a different shock than the ZW7 Nivomat suspension.
    Nivomat is self-contained, Auto-Ride is powered.
