What size lift do I have

New to the Tahoe world.
My truck came with a lift and 285s. Not sure on the actual size of lift. Or who makes it. The original owner painted all the parts black but looks like it was stock red. The steering stabilizer is made my Rancho. Any help Thanx.

I'm slowly realizing this forum blows. No one replies to anything. A million views but no reply's. Oh well off to the next.
