Designed for those who already have a Rubicon Express Super-Flex short arm suspension system, this kit will allow for an easy upgrade to our Extreme-Duty Long Arm System. This package includes a stout 1/4" thick, three-piece belly pan for easy transfer case and transmission access; rear stainless steel brake line and the six Rubicon Express chromoly long arms needed to upgrade your existing short arm system to an Extreme-Duty Long Arm suspension system. We use 2" x .250 wall Chromoly tubing for our lower control arms for serious off roading use. Lift height depends on the system you are upgrading. Exhaust Modification Required. Note: Upgrade systems re-use RE3780 adjustable upper control arms included with Rubicon Express Super-Flex Short Arm Systems. Bushings are provided to convert front upper arms to RE4020. Check your current application.
