JK Wrangler

The Rubicon Express 4-link Extreme-Duty Long Arm system is the most advanced suspension system available for JK Wranglers. These high performance suspension systems deliver performance and control that are unmatched by any other long arm kit on the market. 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 engineered to provide superior handling without limiting articulation. The kits FULL WIDTH heavy-duty transmission crossmember allows for more durability and frame rigidity. This also allows for an easier installation because there is no welding required. Systems can be ordered in 3.5”, 4.5” and 5.5” lift heights with optional high performance monotube shocks. Like all Rubicon Express systems, these are made in the USA and backed by the Rubicon Express Advantage Lifetime Warranty
