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 used the MOOG Z71 springs and 5100s on my 01 and they lifted it about an inch after settling. I’m looking for more performance/stability than comfort. If I’m not mistaken there were 3 different spring rates available.

Just curious Mark--but could you have just replaced that broken tube with a jy tube?
I am thinking I’ll fix this and keep it as a spare. I can order a new tube for $70 and the bearings and seals are about $125 for both sides. But I wanted a rebuilt diff so that’s what I went with and if I manage to break it I’ll have something to swap in. I have been thinking I need a spare front and rear diff and transfer case, because supercharger. They all have 170k on them. The trans should be good now, fingers crossed.

I did the conversion on my ’01 with ZW7/G65. The spring on the left is the Moog Z71 spring #81069. The spring in the center is the standard Moog spring #81071. The spring on the right is the factory ZW7/G65 spring. I ended up going with the standard spring on my leveled ’01.

im sure it is, im waiting for some of the plastic push pins to come in today and ill adjust it more
Cool. Believe me, I wasn't criticizing. I was just wondering if the crashbar behind the front fascia was damaged. Did you also do the side lower mouldings? Have a side view?
