Rock Krawler JL35X2NL-392TR X Factor X2 No Limits Trail Runner 3.5-Inch Long Arm Suspension System 392

The Rock Krawler JL35X2NL-392TR is a 3.5-inch X Factor X2 No Limits Trail Runner Long Arm Suspension System purpose-built for the Jeep Wrangler JL 392 platform. This coilover-equipped long arm system is engineered for hardcore rock crawlers who demand maximum articulation, trail performance, and a tunable ride — all while accommodating the extra weight of the 392's massive V8 engine.

The 392-specific coilover valving and spring rates are calibrated to deliver a true 3.5 inches of lift over the factory 1-inch ride height, resulting in a balanced, functional stance that works with — not against — the front-heavy 392 drivetrain.

Key Features:

• X Factor X2 Long Arm Geometry — Independent 3-link design front and rear for maximum suspension articulation and off-road performance
• Trail Runner Coilover System — Front coilovers with 392-specific valving and spring rates tuned for the V8 engine's weight distribution; includes Fast CD (Compression Dampening) adjusters for enhanced on-the-fly tunability
• No Limits Sway Bar Links — CNC-machined billet aluminum center section with Made-in-USA FK heim joints, designed to work with the factory Rubicon electronic sway bar disconnect for full articulation at the push of a button
• X2 Rear Suspension Geometry — Provides adjustable anti-squat with enhanced rear instant center and rear roll center correction
• 392-Tuned Spring Rates — Heavier coilover spring rates engineered to support the 392 cubic inch V8 and maintain proper ride height and handling balance
• Double-Adjustable Upper Control Arms — Allow precision tuning of caster and pinion angle front and rear, with upsized 14mm hardware and 1-inch Pro Krawler joints at each end
• Adventure Series Maintenance-Free Joints — Located at frame connections on lower control arms to eliminate grease points and reduce control arm bind
• Geometry Correction Included — Correction pads and front/rear track bar geometry corrections included to properly center axles and eliminate on-road handling compromise

The Trail Runner designation indicates this system includes Rock Krawler's coilover shock package with compression dampening adjusters, delivering an additional level of tunability for ride, handling, and off-road performance beyond a standard coil spring setup. This system is designed for Rubicon owners who want a complete, trail-ready long arm solution that excels from the daily commute to the most demanding rock crawling terrain.
