Just finished doing the complete write up on fitting the over the knuckle flip. This gives more clearance for the tie rod as well as reducing the steering effort due to the flatter links. It was quite noticeable. This gives a longer lasting setup then using hemi's and when combined with a V8 ZJ tie rod, a very strong one too.
Also wouldn't mind knowing from anyone who has done this before what backspacing is the most you can have if running 15" rims.
You find it with the write up on lifting the swaybar links as well as the trackbar axle bracket in the suspension and steering section of my site.

This can also be done exactly the same way on a TJ by just using a LHD drag link.
