We don't recommend Rustys. Too many customer service issues over the years.
Look into Hell Creek Suspension 4.5 lift leafs and Iron Rock, Zone, Rubicon express front suspension stuff.
I run the Hell Creek leafs, (3") Iron Rock Off-road adjustable control arms, IRO coils, IRO double shear track bar (highly recommended), and Bilstein 5100 shocks and LOVE the setup. The leafs took awhile to break in but after driving around for 100 miles with 300lbs of sand in he box and hauling the jeep on my trailer with the sand from MN to UT, they broke in nice!
