The Rock Krawler JL45AX2NL-392S1 is a 4.5-inch Adventure-X2 "No Limits" Long Arm Suspension System (Stage 1) purpose-built for the Jeep Wrangler JL 392 platform. This system is engineered to deliver the ideal balance between comfortable daily driving and serious off-road performance, with 392-specific engineering throughout.
The "Adventure-X2" designation reflects the system's full high-clearance 4-link long arm front suspension paired with a high-clearance independent 3-link rear suspension, delivering enhanced instant center and roll center geometry for maximum articulation and trail capability. The X2 rear axle bracket system also gains 4.5 inches of ground clearance under the rear axle compared to stock.
The "No Limits" name comes from the inclusion of specially engineered front sway bar links designed to work with the factory Rubicon electronic sway bar disconnect feature, allowing full articulation at the press of a button. These links feature factory-sized hardware, a CNC-machined billet aluminum center section, and USA-made FK Bearing heim joints.
Because this kit is tuned for the 392, it includes 392-specific Triple-Rate coil springs calibrated to a heavier rate to properly support the weight of the 392 cubic inch V8 engine, while still delivering 4.5 inches of lift over the factory 1-inch ride height. All four coils are designed with the correct free-length for off-road articulation and improved on-road comfort over factory linear-rate springs.
