Rock Krawler JT45AX2NL-TR 4.5 Inch Adventure-X2 No Limits Trail Runner Long Arm System

The Rock Krawler JT45AX2NL-TR is a 4.5-inch Adventure-X2 "No Limits" Trail Runner Long Arm Suspension System engineered for the Jeep Gladiator JT platform. This comprehensive long arm lift kit delivers the ultimate balance between daily driver comfort and hardcore off-road capability, pairing a full high-clearance 4-link long arm front suspension with a high-clearance independent 3-link long arm rear suspension for maximum articulation on any terrain.

The "Trail Runner" designation signifies a full coilover configuration front and rear, featuring 2-5/8" RRD Remote Reservoir Racing Coilovers that deliver both outstanding on-road ride quality and serious off-road performance. Coilovers add a complete level of tuneability, allowing the owner to fine-tune ride, handling, and off-road performance to their preference.

The "Adventure-X2" architecture uses an independent 3-link design both front and rear for maximum articulation. The rear suspension utilizes X2 geometry with enhanced rear instant centers and roll centers, providing adjustable anti-squat characteristics. High-clearance X2 axle bracket mounts deliver 4.5 inches of additional ground clearance under the rear axle compared to stock, while rear upper shock relocation brackets preserve full shock and suspension travel.

The "No Limits" designation comes from the inclusion of specially engineered front sway bar links designed for use with the factory electronic sway bar disconnect feature found on Rubicon models. These sway bar links feature factory-sized hardware, a CNC-machined billet aluminum center section, and Made-in-USA FK Bearing heim joints — simply press the button and hit the rocks.

All control arm joints in the Adventure-X2 system are 100% service-free, isolating harsh road vibrations while delivering high misalignment capability. A steel sleeve fitted with a Teflon-lined inner sleeve ensures the bolt rotates freely without chafing, twisting, or deforming the bushing material. Heat shield thermal barrier products protect the front control arm joints at the frame, just like OEM.
