Bilstein 4600 or 5100???

[2006Tahoe2WD]

I just ordered a set of 4600's for the front of mine. They will be replacing the stock red shocks. I have almost 70k on the clock so I guess it is about time to replace them. I have the nivomat ZW7 premium ride shocks in the rear. Anyone know how long these things last?

How did this turn out for you?
I'm considering the Bilstein 199021 springs and 4600 Bilstein shock set.
Rear 24-143806
Front 24-065009

4600's here, they ride great and control everything just fine, but they are a little soft for my liking as well.

Anthony,
Thanks for the note. I'm still thinking the 4600 series. I'm old and want a smooth quiet ride. I have a sports car with Bilstein sport - so if I want a bumpy ride I have that available to me.
My current question is when changing out of the ZW7 RPO (Premium Ride) to "standard" shocks why not just get stock springs from GM? They don't cost that much, maybe less than the Bilstein (1999021) or Eibach (pn not known) springs.

How do you transfer the spring perch from the OEM strut/shock to the new Beilstein 4600 shock to form a complete strut assembly to reinstall? Thanks.

I am replacing everything and wanted to know are the Bilstein 199021 springs for autoride or for stock springs? I dont have a autoride on my truck and want to buy the correct item.

I assume your talking about a front coil over? If so I took a set from my buddy's Trailblazer to a local shop and they loaded them for $50.

Found my answer- swap over the OEM spring seat :http://cart.bilsteinus.com/pdfs/E4-WM5-Y344A00.pdf
