Rock Krawler JL45AX2NL-4 4.5 Inch Adventure-X2 No Limits Long Arm Suspension System

The Rock Krawler JL45AX2NL-4 is a 4.5-inch Adventure-X2 "No Limits" Long Arm Suspension System engineered to deliver the ideal balance between daily street driving comfort and hardcore off-road performance. This complete long arm lift kit transforms the suspension geometry of the Jeep Wrangler JL 4-door with a full high clearance 4-link front suspension paired with a high clearance independent 3-link rear suspension for maximum articulation and control on any terrain.

The "Adventure-X2" designation signifies a service-free long arm system — no greasing required — built with 100% Service Free Adventure Series joints throughout. The system includes 8 fully adjustable control arms that allow precision tuning of caster and pinion angle front and rear, reducing the inherent bind found in factory JL control arms.

The "No Limits" name comes from the inclusion of specially designed front sway bar links compatible with the factory electronic sway bar disconnect feature found on Rubicon models. These sway bar links feature a CNC machined billet aluminum center section and Made-in-USA heim joints from FK Bearing, allowing full articulation at the press of a button.

Key Features:

• 4.5-inch lift height (based on Rubicon models with standard build)
• Full high clearance 4-link long arm front suspension
• High clearance independent 3-link long arm rear suspension with X2 rear geometry
• Enhanced rear instant center and rear roll center for superior ride quality
• High clearance rear axle mounts provide 4.5 inches of additional ground clearance under the rear axle vs. stock
• Rear upper shock relocation brackets retain full shock and suspension travel
• Triple-rate coil springs front and rear for exceptional on-road comfort
• 100% service-free Adventure Series joints — no greasing required
• No Limits CNC machined billet aluminum sway bar links with FK Bearing USA-made heim joints
• Correction pads included to reduce factory spring bow
• Front and rear track bar geometry corrections to perfectly center axles
