3.5 Inch Adventure-X Long Arm Suspension - 4 Door JKU

The Rock Krawler 3.5 Adventure-X Systems is the ultimate in compromise between daily driver/hard core off-roader. The Adventure-X systems combine the benefits of a full high clearance 4 link front suspension with a high clearance independent 3 link rear suspension. This is where conventional on road handling meets bad a$$ off-road ability. The rear system uses our tried and true independent 3 link conversion with X2 rear suspension geometry with enhanced rear instant center(s) and rear roll center(s). The new high clearance axle mounts provide 4.5" of ground clearance under the rear axle as compared to stock. The rear upper shock relocation brackets ensure you do not lose any shock or suspension travel. The combination of a full high clearance 4 link long arm front suspension and high clearance independent 3 link rear long arm suspension lets you dominate the streets and the trails.

*XR Package does not require OUR raised rear track bar bracket, the factory axle has a raised rear trackbar bracket, and for OUR systems that do not have a rear trackbar one must be added.

*If building with a spare delete, we recommend dropping 1” in coil lift height for the rear.

*If building an overland or heavily upfitted build in the back, we recommend upsizing 1” in coil lift height for the rear.

*Recommend a new front C.V. driveshaft for all front shocks with max. extended length greater than 29"
