ZW7 Premium Smooth Ride Shock replacement

[DaleJr]

Hey guys from what I understand I have the "premium smooth ride" code ZW7 not autoride. My trucks got 162k and I figured I'd go ahead and replace upper/lower control arms, inner/outer tie rod ends and front and rear shocks/springs for the rear. I don't have any issues now just figured it's time to replace since it's got 162k and they are still the stock ones. Should I not worry about it yet? i know they're around $250-$300 a piece, does anyone know where to get a good deal on them? Thanks

I replaced my rear shocks because one was leaking. Best price I found was these on Amazon:

Thanks Screamn03! Anyone running bilstein 4600 or 5100 series shocks for the rear? I saw on their website that It'll work with the premium smooth ride just have to get their springs as well. How do they ride compared to stock?

ZW7 is Nivomat (self adjusting) not Autoride.
Are we sure of the ACDelco # for those on Amazon?

580-354 seems to be the correct number for the ZW7 replacement (self leveling not connected to a control system) - they were $218/ea. on Amazon maybe that has changed a bit, now they look like $257/ea.

I don't know if you tow anything or load the back down. But I do and honestly I really like my zw7 shocks. I have loaded my truck down front to back, top to bottom and still didn't squat... when mine go out, I'll be replacing them with the same ones.

Plenty of people have swapped for bilsteins and z71 coil springs. They seem happy with the ride. But I don't want to mess with helper bags when towing or loading the back down

Replaced my ZW7 with bilstein 5100's and Z71 springs. I think it rides better, doesn't feel like a mushy pos. I don't tow anything though.

We have 02 yukon 4x4 with 161 k miles rpo codes g65 and zw7. Just replaced with acdelco 540-184 for fronts and 580-354 rears and what difference. Our stock shocks weren't horrible...no bouncing but was starting to notice potholes and ruts hit a bit harder past year. Should have replaced 60k miles ago.

Not sure how I originally figured out that part number but I researched it some more.

The short version is 580-354 is for Tahoe/Yukon where the 540-532 is Suburban/Yukon XL based on this:

The previous owner had replaced the original springs on mine with the Z71 and regular shocks. I put the 540-532 on and although it did raise the rear a little more than I liked it seems to work well, especially when loaded heavy. Still trying to find a set of ZW7 springs to swap out and try to see if the ride is any better.

I got the new Nivomats from Amazon and installed them yesterday along with new front shocks. The ride is better. The feeling of hitting bump stops is gone.
