Rock Krawler JL45X2PLA-4DS1 4.5 Inch X-Factor X2 Pro Long Arm Suspension System Stage 1

The Rock Krawler JL45X2PLA-4DS1 is a 4.5-inch X-Factor X2 PRO Long-Arm Suspension System engineered for the Jeep Wrangler JL 4-Door. This Stage 1 system delivers an exceptional balance between daily driving comfort and hardcore off-road capability, making it one of the most capable long-arm lift kits available for the JL platform.

The PRO designation signifies the inclusion of billet aluminum lower control arms that are custom machined in-house from solid square stock billet aluminum, engineered to handle extreme trail abuse while remaining service-free.

Key Features:

• Independent 3-Link Front & Rear Design — delivers maximum articulation and off-road performance with no natural binding points
• X2 Rear Suspension Geometry — provides adjustable anti-squat with enhanced rear instant centers and rear roll centers for improved stability
• Double Adjustable Upper Control Arms — proprietary chromoly solid steel arms with upgraded 14mm hardware, 2-3/8" mounting width, and 1" Pro Krawler joints at each end for precise caster and pinion angle tuning
• High Clearance Axle Mounts — new X2 axle bracket system provides 4.5" of additional ground clearance under the rear axle compared to stock
• Adventure Series Maintenance-Free Joints — used at frame connections on the lower control arms to reduce grease points and provide excellent vibration absorption and joint misalignment capability off-road
• Rear Upper Shock Relocation Brackets — ensure full shock and suspension travel is retained
• Triple-Rate Coil Springs — tuned front and rear coils deliver on-road ride quality that exceeds OEM linear-rate springs while maintaining proper free-length for off-road articulation
• Track Bar Geometry Correction — front and rear correction hardware included to properly center both axles and eliminate on-road handling compromise

All Rock Krawler JL systems include spring bow correction pads to address the inherent factory setup deficiency. A professional alignment by an off-road experienced specialist is recommended after installation. The X-Factor X2 system is backed by Rock Krawler's abuse-proof lifetime warranty on all hard parts.
