Rock Krawler JL45AX2LA-4S1 4.5 Inch Adventure-X2 Long Arm Suspension System Stage 1

The Rock Krawler JL45AX2LA-4S1 is a 4.5-inch Adventure-X2 Long Arm Suspension System (Stage 1) engineered to deliver the ideal balance between daily drivability and serious off-road capability. Designed and manufactured in the USA, this comprehensive Stage 1 system gives your Jeep Wrangler JL a significant lift while dramatically improving articulation, geometry, and trail performance.

The Adventure-X2 architecture pairs a full high-clearance 4-link front suspension with a high-clearance independent 3-link rear suspension, providing superior geometry over stock and vastly improved wheel travel front and rear. The X2 rear suspension geometry features enhanced rear instant centers and roll centers for better handling both on pavement and on the trail.

• 4.5-inch suspension lift with long arm geometry for improved ride quality and articulation
• High-clearance 4-link front suspension with service-free Adventure Series joints — no greasing required
• Independent 3-link rear conversion with X2 rear suspension geometry
• High-clearance rear axle mounts provide 4.5 inches of additional ground clearance under the rear axle versus stock
