Rock Krawler JT45PNL-TR 4.5 Inch X Factor Pro No Limits Aluminum Mid-Arm Trail Runner Suspension System

The Rock Krawler JT45PNL-TR is a 4.5-inch X Factor PRO "No Limits" Mid-Arm Trail Runner Suspension System engineered for Rubicon Gladiator owners who demand a complete, bolt-in solution with maximum off-road articulation. All 8 control arms are constructed from solid 7075 aluminum and incorporate Rock Krawler's award-winning X Factor design for outstanding durability and performance on both the street and the trail.

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

The Trail Runner configuration pairs RRD 2.625-inch remote reservoir racing coilovers both front and rear, delivering 13 inches of front shock travel (yielding 14.4 inches of axle travel) and 12 inches of rear shock travel (yielding up to 15 inches of rear axle travel). Coilovers add an additional level of tuneability for the driver to dial in ride, handling, and off-road performance to their preference.

Key Features:

• 4.5-inch lift height with bolt-in mid-arm architecture
• All 8 adjustable X Factor control arms machined from solid 7075 aluminum
• 95 degrees of total misalignment when paired with Adventure Series and Pro Krawler joints
