Seriously. From Mr. Closethehoodandwalkaway himself, no less.

Mark made me open the hood in the first place! I had to see if mine had the threaded pulley. Since I was already there and the grinder was within arm's reach and I had 5 minutes to spare...

I guess I was just feelin frisky to actually do stuff outside for a change. This weather has me like a dog when the tie-out snaps.

I'm just gonna close this tab and walk away. I don't belong in the GMT800 section, anyway.

Word. Especially since I've now opened up a can of worms. Probably gonna have to clean and paint the other pulleys now. :rolleyes:
Yeah I took a look at painting the pulley on the Silvy and decided there’s about 100 other things under the hood that would start bothering me if I start with that so I walked away. Maybe on The Beast since I’ve already put in some work under there lol.

I’m pricing shocks for my ride and the Bilstein 5100 note says except ZW7 RPO code. Well I just so happen to have the comfort plus ZW7. Will they still work or is there something that different about it?

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?

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

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. :mad:

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