Rock Krawler JL45AX2NL-4S1 4.5 Inch Adventure-X2 No Limits Long Arm Suspension System Stage 1

The Rock Krawler JL45AX2NL-4S1 is a 4.5-inch Adventure-X2 "No Limits" Long Arm Suspension System Stage 1 engineered to deliver the ideal balance between daily drivability and serious off-road capability. This complete long arm lift kit combines a full high-clearance 4-link front suspension with a high-clearance independent 3-link rear suspension for outstanding articulation and trail performance.

The "Adventure-X2" designation means the system is equipped with 8 fully adjustable control arms featuring Rock Krawler's 100% service-free Adventure Series joints, offering up to 70 degrees of total misalignment when paired at the frame and axle connections. This dramatically reduces the inherent bind found in factory control arms and allows precise tuning of caster and pinion angle front and rear.

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. The sway bar links feature factory-sized hardware, a CNC machined billet aluminum center section, and Made-in-USA FK Bearing heim joints — simply press the button and hit the rocks.

Key Features:

• 4.5 inches of lift height with long arm configuration for improved suspension geometry
• High-clearance 4-link front and independent 3-link rear suspension design
• X2 rear suspension geometry with enhanced rear instant center and roll center management
• High-clearance rear axle mounts providing 4.5 inches of additional ground clearance under the rear axle vs. stock

• Front and rear track bar geometry corrections for precise axle centering
• Service-free Adventure Series joints — no greasing required

Designed for the Jeep Wrangler JL 4-door platform, this Stage 1 system provides everything needed to transform your Wrangler's suspension into a capable, trail-proven setup without sacrificing everyday ride quality.
