2003 Yukon XL ZW7 swap

[aztecnavajo]

Hey guys,
My Yukon XL has the ZW7 auto leveling suspension. Previous owner swapped the shocks for conventional shocks w/o touching the coil springs and the truck rides like shit. The ass end sags and is spongier than SpongeBob. I found these on amazon and was wondering if they'd help with the issue I'm having, any suggestions are welcome too. Looking at a possible 1-2 inch lift in the future too so are these coils ok for that? Please and thanks.

yea those will work. if you want to lift the rear more later you can add spacers

Supposedly those Z71 springs add about 1inch lift. others have claimed more and less lift from them, but average is about an inch. I have the ZW7 as well, honestly when my shocks go out, I will probably replace them with the same, I really like the auto load leveling from them

finally got around to swapping the springs out and the truck feels better, but you were right about that ~1" lift in the rear, for the moment I want to level the front so its not sitting lower than the rear, would the stock keys be ok or should I get the f150 keys I keep hearing about?

That's good to know.

Yea you can crank stock keys, but I would pick up some aftermarket lift keys and try those out first.

If you really want to go all out id suggest doing bilstein 5100s all around and then either put moog springs, or just get bilstein replacemnet springs that go with the shocks.
you can always get a pair of cheap reliable keys for the front off of ebay

That's the plan! Lol the new springs are moog and saving up for some blistiens.

this is what my 03 Yukon looks like after Bilstein 5100's and the springs you posted. As matter of fact I ordered everything from Amazon just reading through these threads. I had to do it because my Air ride finally gave out and was looking at an alternative solution and of course to save some money. I can state the Vehicle runs fine through turns with these shocks and you maintain the comfort of the old air ride system. At least that's my experience. I also have torsion keys up front to level it out. It's sitting on 18's with 33"s

How much was everything in total? And where did you get the torsion keys from?
