The latest addition to the Rubicon Express JK suspension offering is our complete 4-link front and rear 3-link extreme-duty long arm system with progressive coils.

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 competitor's 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 inch, 4.5 inch and 5.5 inch lift heights with optional high performance monotube shocks.
Progressive coils have a longer extended length vs. Linear coils, maximizing droop travel. The progressive spring rate also results in a smooth ride over small bumps with enough spring rate to prevent harsh bottoming during full compression.
