Help identifying lift

[Swede has a TJ]

A previous owner installed what I'm pretty sure is a 3" lift.
The springs and shocks are grey with no real markings or identification. I've looked at some kits trying to figure out the manufacture. But nothing seems definitive to me.
Anybody got any ideas?

Most likely Rubicon Express.

Most likely Rubicon Express.

Sounds like it. Pics would help

Gray makes me think Rubicon Express.

The Nth Degree 3" springs were gray, but I'm betting it's not those.

Trailmaster springs are grey too. Pics of them and the control arms if they aren't stock would help. Also what material the tcase drop is if it has one.
