Jeep Wrangler JLU 3.5 Inch Adventure X 4XE Mid-arm System With IFP Shocks Rock Krawler

Rock Krawler 3.5 Adventure - X Mid-Arm Suspension System for Jeep Wrangler JLU (4XE Models)

The Rock Krawler 3.5 Adventure - X Mid-Arm 4XE System is specifically designed for Sport and Sahara owners who want a complete system, bolt-in installation, and the best articulation of any mid-arm kit on the market. Our system proves its durability and off-road performance every time you hit the streets or trail!

The term Adventure - X comes from the inclusion of 8 adjustable control arms with our 100 percent service-free Adventure Series joints installed. Our industry-leading, Adventure - X mid-arms feature adjustable upper and lower control arms and offer a total of 70 degrees of misalignment when paired with our Adventure Series joints at the frame connection and at the axle.

The inherent bind in a factory JL control arm is greatly reduced. With so much adjustability, it allows you to precision tune the JL's caster and pinion angle front and rear.

Driving you home with the most comfortable ride possible in a Wrangler, are our Triple Rate coils. All 4 coils work together to achieve excellent on-road comfort that we feel is better than the OEM linear rate springs.

The coil itself is built with the proper Free-length for off-road articulation and stays firmly seated in the coil bucket (as long as a proper length shock is installed), and overall has a very controlled reaction to bumps, rocks, sand, mud and whatever else you can manage to throw at them! All Rock Krawler JL systems include correction pads that reduce the spring bow inherent in the factory setup.

The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in on-road handling. When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, in tow or down a trail!

• If building with a spare delete we recommend dropping 1 inch in coil lift height for the rear.
• If building an extended off-road and expedition travel or heavily upfitted build in the back, we recommend upsizing 1 inch in coil lift height for the rear.
• We recommend a new front driveshaft if you plan to off-road routinely.
