go with the 4wd harware 2inch springs and spring over with greasable shackles.One of my employees runs this and its awsome.their spring rate is really soft anf springs flex great for their length.we were getting ready to do a yj conversion when 4wd said try our springs,we did and saved some money on the conversion.before we tried 2 other kits,superlift and procomp both would jar your teeth.
