landcruiser tabletop

Hi all,
Just curious, does anybody out there have a very well articulating hzj75 tabletop. My springs are not very old, 20k km (40mm raised h/duty, and articulation is very poor. Had a dual cab hilux (procomp suspension, no locker and a typical not working toyota lsd) go through a serious of holes in 2wd where i could not in 4wd (both of us in first h/r, no run-up, same speed), bit ordinary. I understand that my suspension may be too stiff and suited better for carrying loads. I posted a thread about front sway bar removal, if any benefit. To answer my own question (because i got no replies) i removed it and rasied one front wheel until rear wheel lift, gained a whole 8mm and found very little difference on road, none in the bush (doesn't seem to do much). I realised i can buy new OME or procomp etc, but has any body had real success, don't hear/see much about hzj's as big articulators (custom an exception)
Please don't tell me just install lockers, i realize what they do, i am wanting info about articulation. Thanks.
