The Rock Krawler JL45X2NL-2TR is an extreme-duty 4.5-inch lift suspension system engineered for serious rock crawling on Jeep Wrangler JL models. This Trail Runner configuration combines front and rear coilover setups with long arm geometry to deliver maximum articulation and ground clearance for hardcore off-road applications.
X Factor X2 Independent 3-Link Design:
- Front and rear independent 3-link suspension architecture provides exceptional articulation and off-road performance
- X2 rear suspension geometry with adjustable anti-squat and enhanced instant centers and roll centers
- High clearance axle mounts add 4.5 inches of ground clearance under the rear axle compared to stock
- Chromoly solid steel control arms with double adjustable upper arms featuring 14mm hardware and 2.375-inch mounting width
- Pro Krawler joints at each control arm connection point for maximum durability
- Maintenance-free Adventure Series joints at frame connections reduce grease point maintenance
No Limits Sway Bar Compatibility:
The No Limits designation refers to the included front sway bar links specifically designed to work with the factory Rubicon electronic sway bar disconnect feature. These links feature CNC-machined billet aluminum center sections with FK Bearing heim joints made in the USA, allowing full articulation while maintaining the convenience of factory sway bar control.
Trail Runner Coilover Configuration:
Front and rear coilover shocks provide exceptional tuneability, allowing owners to dial in ride quality, handling, and off-road performance to their exact preferences. The relocated rear upper shock mounts ensure full suspension travel is maintained throughout the lift range.
Installation Notes:
- Requires welding of front and rear long arm mounts and coilover axle mounts
- Requires removal of OEM frame and axle-side control arm mounts
- Aftermarket front axle housing with FAD delete required for front upper arm mount welding
- Steersmart XD Yeti HD bottom mount drag link recommended for off-road use
- CV front driveshaft recommended for shocks with extended length greater than 29 inches
- Limiting straps recommended to prevent over-extension of suspension components
Designed and manufactured in the United States, Rock Krawler suspension systems are proven on custom one-off builds before being refined for production, ensuring real-world performance and durability.
