It's not worth the $500 in my strictly personal opinion for a rig built like yours or mine. My TJ does fine on some pretty darned tough trails with an Antirock up front and the OE antiswaybar in the rear with extended links.What I don't know is if the anti rock on the rear is worth the $500 sticker price since the stock sway bar is a smaller diameter then F. Stock and pretty flexy. For a mild build ( 4" SA on 33's)
