Rock Krawler JT45X2NL-TR 4.5 Inch X-Factor X2 No Limits Trail Runner Long Arm Suspension System

The Rock Krawler JT45X2NL-TR is the 4.5-inch X-Factor X2 "No Limits" Trail Runner Long Arm Suspension System, engineered for hardcore rock crawling with a full front and rear coilover setup. This system delivers maximum articulation and off-road performance through its independent 3-link design at both axles — a proven Rock Krawler architecture that has set the benchmark for long arm suspension geometry.

The "No Limits" designation refers to the inclusion of specially designed front sway bar links compatible with the factory electronic sway bar disconnect feature, allowing Rubicon owners to utilize that functionality while still achieving full suspension articulation. The sway bar links feature a CNC machined billet aluminum center section and Made-in-USA heim joints from FK Bearing.

The "Trail Runner" configuration pairs 2.625" RRD Racing Coilovers with Remote Reservoirs at all four corners for maximum off-road tuneability and performance. Coilovers add an additional level of adjustability, allowing owners to fine-tune ride quality, handling, and off-road capability to their preference.

Key Features:

• 4.5" lift over stock ride height
• Independent 3-link design front and rear for maximum articulation and off-road performance

• Double adjustable front and rear upper control arms upsized to 14mm hardware, 2-3/8" mounting width, and 1" Pro Krawler joints at each end
• Chromoly solid steel arms engineered to handle the full forces of the suspension
• Adventure Series maintenance-free joints at the frame-side lower control arm connections to reduce grease points and provide excellent vibration absorption
• Rear upper shock relocation brackets to preserve full shock and suspension travel
• Weld-on rear upper shock mounts, axle-side control arm mounts, rear track bar mount, and rear axle truss included

Installation Notes: This system requires removal of OEM axle-side rear lower control arm and track bar mounts, modification of OEM rear shock mounts, and welding of new raised rear upper shock mounts and coilover mount on the axle. Installation of limiting straps after setup is strongly recommended. Fabrication experience and suspension setup knowledge are required.
