New-Nivomats... ( Old subject/new problem ) Do they exist??

[mountie]

I took some weight out of my '05 Yukon XL w/ ZW7.....
I measured the rear fender.... after empty, drove over 20 miles... Same height.
The ride 'feels' fine.... But , looking for new Nivomats..... WHO SELLS THEM????

I don't drive a Chrysler..... ( in stock ).... GMC Yukon..... nope....

A better test for the Nivomats is to ADD weight and measure before moving, then after driving a bit. Your test has the shocks already compensating for weight, so why would the height change much when you took away the weight -- if they're working?

Rock Auto, for one, has a couple of choices:

Uh,,,, Same fender height before weight & after weight removal.... after a 20 mile drive. ( sorry, I miss-wrote)
( I did, also, adjust my Hellwig rear bar, to the stiffer hole, while I was under there )

I can read your RA photo.... Maybe a Tahoe shows different info.( Your part number is different ).
I find, in the '05 Yukon, REAR, but for RWD..... not 4WD. GM part.
( A bit confusing, as they say. "not for"...... bla-bla-bla....
I want to be careful ordering, due to the cost!!

EDIT....... I ordered a pair on Amazon ( genuine GM - new)..... We'll see.....

Is your XL 4WD? You didn't say.

Do you have RPO code G65? If you do, those are Nivomats. If not, then non-Nivomat.

4wd ....... ZW7 is the RPO code on my Yukon ????

What is G65 for ??

 

[Fless]

G65 is the Nivomat self-leveling shocks. ZW7 is Premium Smooth Ride, which can be a number of suspension parts, and isn't always the Nivomat shocks. Which is why the G65 code is for the rear Niv shocks.

Post a pic of your RPO codes if you want.

4wd

What I ordered may be for a 2wd..... It is complicated to decipher the choices....
But it's easy to return - shipping..... ( Geeze )......

I canceled my 'Nivomat' shocks order last evening..... I want to be sure before ordering...
Checking the Monroe site.... It appears, Nivomat shocks have a thinner - lower - looking shaft on the bottom. The photo I took of mine, seems it has a larger diameter?
( confusing)....

No G65 RPO code on the sticker, so you do not have Nimovat shocks.

Well, well...... I just saved a few bucks.....
So, all you people in this forum..... A couple months ago, I replaced my front shocks, with a pair of "OEM rated" Bilstiens...... What should I replace my rears with, .... since I have a ZW7 'premium' suspension..... ?
BTW.... If I have a "premium ride"..... What makes it, premium??

OK. Disregarding my previous comment regarding the G65 RPO code, I just found this:

What is the ZW7 suspension package?

Premium Smooth Ride: indicated by the RPO code ZW7. This suspension uses a conventional suspension in the front, but the rear uses a self-contained, self- leveling Nivomat shock in the rear.

So, now I am confused, as well. @Doubeleive

So,.... I'm not crazy....... it's confusing.......
( What does the RPO code, " G65" actually describe?? )

 

[mountie]

Searching, Rock Auto, etc, The specific description for a "Nivomat" , shows many variations, for ..RWD, 4WD, ( ext. 20" wheels, not Z71.... )......
I want..... 2005 YUKON XL SLT 4 WD... ZW7 Premium ride - NIVOMAT.....
But none describe it as such..... There are variables..... when selecting.....
Then there's a selection.... Sachs ( WHICH I WANT)...., but the other manufacturer's VERSIONS, but Nivomat is not mentioned....
Grrrrrrrrrr..... I want OEM/ Sachs !! (( Part # 580-354 OR, 530-532 )) ??????

Amazon describes the Yukon XL, "OEM/ZW7" ( "530-532" shock ) as an "air lift premium shock".... BUT NIVOMAT is not said.......

Based on your pic in post #8, I think your 4WD has regular shocks in the rear, first item on the RA list (filtered for GM & rear). The other three are self-leveling shocks and yours do not appear to be that. The RWD chassis seems to have the Nivomat shocks (2nd item on list below).

Can you read any of the characters on the stickers that are on your shocks? Post a pic? How about on the coil springs?

Here's what one of my Nivomats looks like (2004 short WB, 4WD Tahoe); not the same as yours.

I found & purchased a pair of Sachs " Nivomat" shocks......
Nivomat is the old description of these shocks.......
Sachs stopped using their label..... KYB, etc., sells the "Nivomat".... Made by Sachs.....
I found a SMART guy, who sells only shocks..... I spoke with him for a while..... Buyers get frustrated, due to the multiple "terms" of how the shocks perform..... By the different sellers.

The shocks, on my Yukon.... ( the photo I took )..... Are NOT the correct shocks. They are not the original Nivomat. ( I sent the guy the photo )......
He said, the Sachs shock also supports the rear suspension, in a way, regular shocks don't!!
He said, I am going to love the Sachs..... Much better ride.....

He sells 'used shocks', but they are checked & tested... He spends his time, pulling good / used shocks from vehicles..... Many are low mileage, etc. ( He can tell ).....

Ok, good luck with that; I hope it works out. Nivomat is the technology developed by SACHS, and doesn't necessarily show up as a descriptor on every brand that offers it. Based on what I've seen I still don't think yours came with Nivomat technology for the rear shocks; I could be wrong.

I'd be curious if anyone else with an '05 or '06 4WD XL on this forum has ZW7 AND G65 on the RPO list, or if only the ZW7 code shows up.

If your rear shocks were changed, then, perhaps so were the springs. Better start researching those.

I think, I saw a label on a spring....... Thanks for the head's up......

I don't know but it's easy to just call a dealer parts department give them the last 8 of your vin and ask to verify the rear shock part number.

I called Shumacher GMC in Palm Beach..... I was on hold for way too long.......

G65 == manual self adjusting level control. Manual in that it isn't electronic. Thus Nivomat which was created by Sachs.

Here is my build sheet from GM, I have Nivomats on my RWD.
