Rubicon Express JL4400 4 Link Upgrade for 18-20 Jeep Wrangler JL Unlimited

Quadratec Part #: 16300.7130
Rubicon Express Part #: JL4400
Taking your lift kit to the next level on your Jeep Wrangler JL is easy to do with the Rubicon Express 4 Link Upgrade. With no welding required, the bolt-on design makes for a simple install that can be added to an existing lift kit. Extending the length of the control arms offers better approach angles to improve suspension travel and control. These angles are beneficial for off-roading and absorbing bumps in the road while daily driving. Even though less wear will occur due to the change in geometry, the bushings are easily maintained and rebuild kits from Rubicon Express are available.

Articulation: Longer control arms allow the axles to travel further with less pivoting for better control over large obstacles.

Ride Quality: Having the control arms mounted closer to the center of the Jeep will provide a more comfortable ride even over the factory geometry.

Best of Both Worlds: Utilizing both styles of bushing to give you superior control and comfort on any road or trail. The Super-Ride bushings cushion impacts making daily driving easier. Super-Flex control arm ends allow more articulation to help when flexing over obstacles on the trail.
