Which 5100's?

[9C1C]

Hey all - On my 2004 Yukon 4x4 I am replacing the rear springs/nivomats with a set of Z71 springs I picked up. I found that there are different versions or sizes of the 5100 Bilstein shocks, so how can I tell which specific one I need to work with the Z71 springs? For the front, the PO says it has a leveling kit, so how can I tell what size 5100's I need for that as well?

I used a supreme suspension level kit on my 04 z71 and went with the 5100’s for 0-2.5” lift. Shock surplus has them in stock. I purchased mine from them and I’m completely satisfied.

Thanks! Are those the Z71's in back with level kit up front in your thumbnail pic there?

That’s my 02 LT that I sold last year. I’ll upload a pic of my 04

This is with the level and 5100’s

Great looking rig! Thanks for the pic, that helps give me reference. My front end sits just slightly higher than the rear so I'm hoping the Z71 springs give it more of a stance like that.

Thanks! After you install the new springs you can always adjust your front keys to level with back.

Where is everybody getting the Z-71 springs and how much lift / height do they add? Do they require longer rear shocks / mounts?
