Rock Krawler JL35AXPNL-392S1 3.5 Inch Adventure-X No Limits Long Arm Suspension System Stage 1

The Rock Krawler JL35AXPNL-392S1 is a 3.5-inch Adventure-X "No Limits" Long Arm Suspension System (Stage 1) engineered specifically for the Jeep Wrangler JL 392 platform. This comprehensive lift kit delivers the ideal balance between a capable daily driver and a hard-core off-road machine, with every component purpose-built to handle the added weight and power of the 392 cubic inch V8 engine.

392-Specific Triple Rate Coil Springs:

This system includes specially tuned Triple Rate coil springs that deliver 3.5 inches of lift height above the factory 1-inch lift height. The springs feature a heavier rate calibrated specifically for the mass of the 392 V8 powerplant, providing a balanced, functional ride height whether you're on pavement, towing, or attacking a trail.

Adventure-X Long Arm Architecture:

• Full high clearance 4-link long arm front suspension for maximum geometry correction and articulation
• High clearance independent 3-link long arm rear suspension with X2 rear geometry for enhanced rear instant center and roll center performance
• 8 adjustable control arms equipped with 100% service-free Adventure Series joints — no greasing required
• Rear upper shock relocation brackets to preserve full shock and suspension travel
• High clearance axle mounts providing significant additional ground clearance under the rear axle versus stock
• Track bar geometry correction brackets, front and rear, to precisely center both axles for uncompromised on-road handling
• Correction pads included to reduce the spring bow inherent in the factory setup

"No Limits" Sway Bar Link System:

• Specifically designed front sway bar links compatible with the factory electronic sway bar disconnect feature found on Rubicon models
• CNC-machined billet aluminum center section for maximum strength and durability
• Factory-sized hardware with Made in USA heim joints from FK Bearing
• Simply press the factory disconnect button for full off-road articulation — no extra steps required
