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

[JollyRoger01]

Do you have RPO G65? With ZW7 (Premium Smooth Ride) those are the Nivomat shocks on the rear, and changing to a conventional shock requires the coil spring to be changed, too. Need stiffer springs without the Nivomats.

EDIT: any chance the shocks are not OE now?

They’re OE left side is failing.

The Bilsteins spec a companion spring for the conversion. I think most people just change to the standard spring. UPull or new.

Someone on here had a set of used Nivomats for sale, but I can't recall who. If you're interested I'll do a deeper search.

2005? Lifted or OE height?

I guess I just need to go ahead and lower it then. Thank you for the offer.

Someone with more experience with the conversion and lifted suspensions could weigh in on what springs are used.

If I remember correctly, guys switch to Z71 rear springs.

That's what I was thinking. But is there a "standard" OE spring? A third style?

 

[Sam Harris]

Pretty sure the Z71 is about an inch taller. I imagine there’s a “standard” as well but don’t know. I decided I like the functionality of the Nivomats so probably going to stick with those, and do the 5100’s up front.

I was pulling the broken axle housing off my front diff and decdied the only way that thing broke was the amount of torque applied twisted the main housing in its rubber mounts and the axle tube is bolted solid so it twisted the pumpkin enough that the right side twisted up or down enough to break that tube. There’s nothing inside it except an axle. Don’t try a reverse burnout in a boosted AWD.

Just curious Mark--but could you have just replaced that broken tube with a jy tube?
