    I had to replace my rear shocks, at first i thought the sluggish suspension is normal by American cars, but later on, i had the feeling this isn't normal.

    So i ordered from rockauto a pair of coil springs (Moog 81071) and two new nivomat shock absorbers (ACdelco 580-354). Let me tell you, what a difference is that!

    First of all i think it's insane that rear shocks only last about 100k miles, so for all the owners of a Tahoe with the towing package / smooth ride (see you glove box for the numbers: G65 and ZW7)
    Let you rear shocks inspected by a mechanic, pull them out and check for any resistance.

    My old ones, had no resistance or what so ever. I could easily pull and push them with my bare hands.


    Those are the new ones:

    So if you replaced the shocks with nivomat kind again, why did you replace the coil springs?

    Mine has 115k on it and my rear nivomat shocks are still working great, and I have towed a lot of stuff and some really heavy stuff with it. Still levels back to correct ride height. Love mine

    Well, the reason why i also changed the coil springs is more like a preventive measure.
    Why not change the coils as well (its not that much of a money, compared to the nivomat shocks!)

    Nivomat is great, but mine where just blown up. I wrote also a complain letter to sachs (the german company who makes the nivomat's) I think the many speed bumps we have here stresses out the nivomat's to a point they become weak. They are not build for off roading...

    I would not expect shocks to last 100k miles, especially if towing.
