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. The kits FULL WIDTH heavy-duty transmission crossmember allows for more durability and frame rigidity then the competition. This also allows for installation that is much easier that competitors kits eliminating the need for welding. An optional robust belly pan, and CNC machine steering knuckle provide outstanding upgrades. Systems can be ordered in 3.5″, 4.5″ and 5.5″ lift heights with optional high performance monotube shocks.
