I installed some bilstein 5100's set at the 2" level and my cv's look like they are barely affected. It did give a little bit of lift but when I compare mine to others that have installed them, the others have a lot more lift.

Could I have installed the coil springs upside down?

I know I set them at the 2" mark but look at other peoples install, they have at least an 3/4 of an inch more than I do. My rear is still a little bit higher.

If you look at my cvs compared to others that have installed it, mine look like they have barely been affected.

Just wondering mine is different than others.

 

Coils that are in right side up or not will still provide the same exact amount of lift.
With that said, your springs are indeed installed right side up(correct).
The bilstein 5100 lift strut kit is meant to be easier on the cv's and not so harsh like the spacers provide.

Bilstein struts lift up to 2". Some may be slightly more and some may be slightly less. Not every truck/kit will act the same way.
Did you do a measurement before and compare it with an after measurement?
The rear will be slightly higher with a 2" kit and slightly lower with a 2.5" kit so the "perfectly level" sweet spot is in between for these trucks.

Be happy your cv's aren't at a harsh angle and be sure your 4wd doesn't shake at highway speeds. other than that, sound like your looking for a body lift next. ;-)

 

IDK much about the 4wd but i can back up Dirty on the coil spring being upside down or not. It wont matter.

 

Doesn't look that much different from mine:
