The Rock Krawler 4.5 Adventure-X Systems is the ultimate in compromise between daily driver/hard core off-roader. The Rock Krawler No Limits systems feature our No limits front sway bar links that allow Rubicon owners to utilize the factory Rubicon sway bar disconnect feature and still achieve full articulation. 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 inches 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.
