The latest addition to the Rubicon Express JK suspension offering is our complete 4-LINK Extreme-Duty Long Arm system.

They feature adjustable chromoly upper and lower control arms that will stand up to anything you can drive over. With PT-MEG Super-Ride Bushings and Super-Flex Joints they are sure to provide superior handing while not limiting articulation.
