What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Tonyrodz]

Damn they look super skinny next to stockers. Interested to hear how they ride. Are all aftermarket shocks like that ?

Don't really know, but they better be better, or at least comparable. They are KYB's. I'll definitely keep you updated on ride quality. Anyone know where I can get a new bump stop from? I bet it's gonna be a pita too!

You are talking front jounce stop right? @Tonyrodz

Here is Amazon link, but I see many more out there may be better price and color too.

I should have just asked in here instead of making a new thread, have any of you used a sonnax boost valve? If so which one? I understand I should use the first gen for my 2001?

 

[Tonyrodz]

Just ordered a set of Belltech's for $37 shipped. Yellow, oh well.

The jounce stops are gravy to replace. Put it up on jack stands, then just use a small prybar or flathead screwdriver to pop them out. They go in by hand with a twist.

Nice. Thank you Red.

Did my shocks today. Surprisingly all the shocks we're still good. Front end used to wallow. Saw the passenger front bump stop is split. View attachment 71742Had stock shocks all around. Putting the KYB's in we're a PITA! Got them all in tho. Was too late to take it for a test drive to see if the ride improved. Hopefully it was worth the time, effort and money. View attachment 71743 View attachment 71744Look at the size difference. Length is the same, but check out the width.

Btw- Anyone want the Sachs rear shocks? I'd hate to throw good shocks away. Fronts are a little rusty, but I think they're still good also. Free to anyone who wants to pick them up. Front and/or rears. Mailing would kill the free vibe. LolView attachment 71746

Your factory rear shocks look like Nivomat shocks. Do you have RPO code ZW7 in your glovebox?

 

[Tonyrodz]

Not sure. Says Sachs on it. They the same? They're actually pretty heavy.

 

[TM98]

I believe you need both RPO code G65 and ZW7 for the Nivomat shocks

 

[eohat]

If you have RPO ZW7 then you need to swap out the rear springs too. I recently did a ZW7 delete on mine.

Well, that sux! I have it, so what exactly does that mean? And what if I don't swap out the springs? What's the deal with Nivomat shocks? Are they heavy duty? Will the KYB's not be good enough?

 

[TM98]

Yes it will be very soft riding in the rear from what I understand.

Here's some info on the ZW7 option:

I was able to unload mine on Craigslist for 200.00 with the matching springs, when I did my rear lift.

If I'm reading it right, says truck will sag if loaded. I don't really ever load it up, and the sag wouldn't be too bad in my eyes, since it sits higher in the rear then I like anyway. Now I'm just concerned about the handling with the new shocks.

 

[Tonyrodz]

Is it a softer spring that won't work well with the KYB's?
EDIT: I think/hope it'll be OK. Just looked it up on the site and it says I can use the Excel-G's with the ZW7 option. Keep your fingers crossed.

Sweet. If you do decide to replace the springs they’re cheap and easy to install.

My truck rode about 2in lower when I replaced my nivomats with bilsteins. It looked cool rode smooth but didn't have any load handling ability. Even bottomed out once just driving around. Nivomats have a built in spring and you will see you cannot compress them by hand like other shocks. I replaced mine with bilsteins factory spring. Handles better than the nivomats but doesn't have the same load handling ability it did stock.
