i was thinking about cranking up the torsion bars. right now they can go up quite a bit.

 

You will get a few inches. I ran cranked T-bars for a while heres the bad
-Bad ride quality
-Torn CV's within a year or sooner depending on how high you go
-NO flex in the front

I would recommend ball joint spacers like these

shackle swaps are pretty quick and easy.....throw 'em on. If you aren't happy, you might have wasted a couple of hours
