Rock Krawler JL45X2PNL-4 4.5 Inch X-Factor X2 PRO No Limits Long Arm Suspension System

The Rock Krawler JL45X2PNL-4 is a 4.5-inch X-Factor X2 PRO "No Limits" Long-Arm Suspension System engineered for serious off-road performance. Built for hard core rock crawling, this system delivers maximum articulation, superior geometry, and exceptional on-road stability all in one comprehensive package.

The "PRO" designation reflects the inclusion of Rock Krawler's signature PB&J (Pure Beef and Jealousy) billet aluminum lower control arms — custom CNC machined in-house from solid square stock billet aluminum for uncompromising strength and durability.

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

Key Features:

• Independent 3-link design front and rear for maximum articulation and off-road performance
• Double-adjustable front and rear upper control arms with 14mm hardware, 2-3/8" mounting width, and 1" Pro Krawler joints at each end
• Chromoly solid steel upper arms engineered to handle the full forces of the suspension
• X2 rear suspension geometry with enhanced rear instant center(s) and rear roll center(s) for adjustable anti-squat
• High clearance axle mounts providing 4.5" of additional ground clearance under the rear axle versus stock
• Rear upper shock relocation brackets to preserve full shock and suspension travel
• Adventure Series maintenance-free joints at frame connections — fewer grease points, excellent vibration absorption, and proper joint misalignment off-road
• 4-door JL platform-specific engineering and fitment

The X-Factor X2 long-arm system provides a stable, confident feel whether commuting on the highway or pushing through the toughest trails. Rock Krawler designs and manufactures their suspension systems in the USA, applying real-world custom build experience to every production kit.
