Rock Krawler JL45X2PLA-2 4.5 Inch X Factor X2 Pro Long Arm Suspension System

The Rock Krawler JL45X2PLA-2 is the 4.5-inch X Factor X2 Pro Long-Arm Suspension System, engineered to deliver the ideal balance between capable daily driving and hardcore off-road performance. This complete long-arm suspension lift system features Rock Krawler's independent 3-link design front and rear, delivering maximum articulation and improved suspension geometry over the factory setup.

The "PRO" designation comes from the inclusion of Rock Krawler's PB&J (Pure Beef and Jealousy) billet aluminum lower control arms. These arms are custom machined in-house from a solid square stock bar of billet aluminum, built to handle the most extreme trail abuse without compromise.

Key Features:

• 4.5-inch lift — provides significant ground clearance gains for larger tire fitment
• Independent 3-link front and rear suspension — maximizes articulation and off-road performance
• Double adjustable front and rear upper control arms — upsizes factory hardware to 14mm with 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 system
• Billet aluminum CNC-machined lower control arms — custom machined in-house from solid square billet stock
• X2 rear suspension geometry — features enhanced rear instant centers and rear roll centers for improved stability
• High clearance axle mounts — provide additional ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets — preserve full shock and suspension travel
• "Adventure Series" maintenance-free joints — used at frame connections to reduce grease points and provide excellent vibration absorption
• Triple-Rate coil springs front and rear — tuned for superior on-road ride comfort and off-road capability
• Geometry correction hardware included — correction pads and track bar geometry corrections to properly center the axles

The X Factor X2 system combines a full high-clearance independent 3-link long-arm front suspension with a high-clearance independent 3-link rear long-arm suspension, delivering confident performance whether you're commuting on the highway or conquering technical rock crawling terrain.
