What do you need explained?

 

i reckon you could add those to the factory 3 leaf set up and voila........essentially it would be the tsb springs so to speak, well.....kinda anyway. probably would work the same anyway.

 

I'm not sure exactly how these work. I'm looking to lift my Taco but since the whole truck science is new to me I'm a little confused on what all the different possibilites are.

 

even with these aal's, to accheive a 3 inch lift, you would stillprobably need to add a spacer to the rear, along with whatever you use for the front, be it a spacer or adjustable coilovers. at least im pretty sure thats what you'd need to do.
