Can anyone identify this lift?

07 Tundra, bought the truck with the lift. I took it for granted that it was a Rough Country lift since the shocks and struts are Rouch Country, but after getting under the truck and not seeing the same cross members that come with a rough country and then comparing it more closely with my brother's 14 tundra with a rough country lift I am not so sure. Nowhere does it say rough country or any other brand other than the shocks/struts. Shackles look a lot different as well.

 

It's definitely not a BDS lift.

 

looks like it may be....

what I found when I looked up zone kit. Just no extensions for struts since they have been "upgraded"

Thanks!
