Super-Flex Short Arm

The Rubicon Express Super-Flex system is the best suspension for ZJ Grand Cherokee’s running factory short arm suspension geometry. Upgrading your Grand Cherokee with a Super-Flex suspension system will turn your ZJ into a remarkable performing 4x4 machine with a smoother and more flexible ride on and off the trail. The Rubicon Express Super-Flex 4.5” lift replaces your stock ZJ suspension with our high-quality, trail-ready components. It features an adjustable front track bar, lower and upper adjustable rear control arms with our Super-Flex spherical ball joints (allowing necessary adjustments), replacement 4.5” lift springs, and Gen II sway bar disconnects. This is the best ZJ lift available that retains the factory short arm design and utilizes the factory suspension mounting points. This suspension allows the use of 32” tires. The Rubicon Express 3.5” Super-Flex suspension system is for ZJ Grand Cherokee enthusiasts who require a little less lift than the 4.5” system, at a more affordable price. The 3.5” features Rubicon Express Super-Flex lower control arms with our serviceable Super-Flex spherical ball joints, replacement 3.5” lift springs, and Gen II sway bar disconnects. The 3.5” Super- Flex system features the same ride quality and general trail traits as the 4.5” system. This 3.5” suspension package is easily upgraded to the 4.5” version should you decide your ZJ needs more lift in the future. This suspension will allow the use of 31” tires.
