Rock Krawler JT45AX2NL-DCS 4.5 Inch Adventure-X2 No Limits Coilover Long Arm Suspension System

The Rock Krawler JT45AX2NL-DCS is a 4.5-inch Adventure-X2 "No Limits" Coilover Long Arm Suspension System engineered to deliver the ideal balance between daily drivability and hardcore off-road performance. This comprehensive long arm lift system replaces the factory suspension geometry with a full high-clearance 4-link front suspension paired with a high-clearance independent 3-link rear suspension, maximizing both articulation and on-road composure.

The "No Limits" designation refers to the inclusion of specially designed front sway bar links that allow Rubicon owners to retain and use the factory electronic sway bar disconnect feature while still achieving full suspension articulation on the trail. Simply press the button and attack the rocks without compromising street manners.

The Adventure-X2 system features fully adjustable upper and lower control arms equipped with 100% service-free Adventure Series joints. These arms offer up to 70 degrees of total misalignment, allowing precise tuning of caster and pinion angle both front and rear, and significantly reducing the bind inherent in factory control arms.

Key Features:
