What do you mean by "lift spindle"? Do you mean an extension on top, to fit with a drop bracket? That has been done.
Do you mean a spindle where the hub has been moved to a snout outboard of the lower ball joint, rather than above it? I believe they are available in the desert industry, but don't know names OTOH. Camburg makes one, but it is for their race kit. This type of spindle cannot be used with the factory 4WD.
Haha! Well I got suckered into buying the lift spindles. I spent around $800 for the spindles and strut spacers. I just didn't like seeing the skinny ball joint spacer/spindle extender. Plus I plan on adding King Coilovers and the TC UCA in the very near future.....in fact they are on order and hopefully on an airplane heading my way.
