OME 886 Idea? with top spacer?

So I have a 2006 Trd sport 4 door with OME lift 886 and nirochacher 90000 shocks on the front. I was Wondering if it would be a good idea to put a top spacer in? I do have a aftermarket ARB bump on the front too and I didn't get a 2" lift in the front when in lifted it I got just under a 2" lift would top spacer be a good idea or not? and if so what size of a spacer?

 

I have OME 885's on my 06 TRD Sport 4door and it came with a top plate spacer. I think it only gives about 1/2" of lift and I'm pretty sure I got a full 3"s of lift out of it. Maybe a little less since its settled now.
