4 bolt inner box brace, the across frame front brace, the outer brace, and get a ZJ v8 tie rod and flip it over the knuckle, cut off your sway bar mounts, good trackbar (i like the RE HD since you can buy the trackbarbar mount cross brace, which i have and love)
get good shocks, and make sure youre control arm joints/bushings are all good and your steering should be pretty good after that. you could probably do all of the above much cheaper than doing just the currie steeringsetup. then use the money you saved to buy stiffeners .
with the cross frame box brace, cross frame trackbar brace, and stiffeners, your steering will greatly improve.
