The Rock Krawler JL45AX2NL-392TR is a 4.5-inch Adventure-X2 "No Limits" Trail Runner Long Arm Suspension System engineered for the Jeep Wrangler JL 392.

Adventure-X2 Long Arm Architecture:

• High clearance 4-link front / independent 3-link rear long arm suspension design for maximum articulation and off-road performance

• High clearance axle mounts provide 4.5 inches of additional ground clearance under the rear axle compared to stock
• Rear upper shock relocation brackets preserve full shock and suspension travel

Trail Runner Coilover System:

• Features 2.625" coilover shocks front and rear for added tunability and enhanced ride quality on and off the trail
• Triple-rate coil springs deliver on-road comfort superior to OEM linear-rate springs while maintaining proper free-length for off-road articulation
• Coil springs stay firmly seated for controlled response over rocks, sand, mud, and rough terrain

"No Limits" Sway Bar System:

• Sway bar links feature a CNC machined billet aluminum center section with Made in USA FK Bearing heim joints and factory-sized hardware
• Simply press the factory disconnect button for full articulation on the trail

Service-Free Control Arms:

• 8 fully adjustable control arms with 100% service-free Adventure Series joints installed
• Adventure Series maintenance-free joints at frame connections reduce grease points and provide excellent vibration absorption
• PRO Krawler Joints at axle connections for maximum misalignment capacity
• Full adjustability allows precision tuning of caster and pinion angle front and rear

Geometry Correction Hardware:
