Rubicon Express Extreme-Duty Long Arm Kits with Tri-Link System eliminates the need for a rear track bar which allow for a real up or down wheel travel, while also improving the anti-squat for steep terrains. These kits bolt on easily for OEM Dana 35 and Dana 44 rear ends. While having this Tri-Link System, you will experience a much improved on-road tracking. The kits also include front and rear control arms using 2 .250 wall, 4130 chromoly material with Rubicon's newest misalignment joint design, the Builder Ball. This particular setup has 32 degrees of misalignment in a bigger sized 3 inch OD housing.
Extreme Duty Long Arm Upgrade Kits are made for those who already installed a Rubicon Express Super-Flex Short Arm Suspension System. These kits will easily upgrade your existing suspension system to Rubicon Express Extreme-Duty Long Arm System. An exhaust modification is required for this upgrade and lift height will depend on the system you are upgrading. The kits will re-use RE3780 adjustable upper control arms, while bushings are included to convert front upper arms to RE4020. You should check your current application on this. By choosing to upgrade your existing Super-Flex Short Arm Suspension System to Extreme-Duty Long Arm System, you will gain improvements to your LJ’s on road handling and stability.
