Rock Krawler JL45AX2LA-4D 4.5 Inch Adventure-X2 Long Arm Suspension System 4-Door

The Rock Krawler JL45AX2LA-4D is a 4.5-inch Adventure-X2 Long Arm Suspension System engineered for the Jeep Wrangler JL 4-Door. Designed and manufactured in the USA, this comprehensive lift system delivers an ideal balance between daily street driving comfort and serious off-road capability.

Adventure-X2 System Highlights:

• High Clearance 4-Link Front Suspension combined with an independent high clearance 3-Link Rear Suspension for maximum articulation and improved geometry
• Service-Free Long Arm Joints — engineered sleeve design acts as a buffer between bracket clamping force and the bushing, eliminating the need for greasing and producing zero noise in the housing
• 4.5 Inches of Rear Ground Clearance Gain from the X2 high clearance axle bracket system compared to stock
• Enhanced Rear Instant Center and Roll Center geometry for smooth, controlled ride quality on road and off
• Rear Upper Shock Relocation Brackets preserve full shock travel and suspension articulation
• Spring Correction Seats front and rear to extend coil spring life and reduce factory spring bow
• USA-designed and manufactured components with premium hardware and detailed installation instructions included

Installation Notes: This system requires removal of OEM frame-side lower and upper front and rear control arm mounts, welding of front and rear long arm frame-side mounts, and welding of provided rear axle-side control arm, shock, sway bar link, and track bar brackets. Limiting straps are recommended after final setup to prevent over-extension of suspension components. A front driveshaft upgrade is recommended for frequent off-road use.

The Rock Krawler Adventure-X2 platform is built to be the foundation for every adventure — whether cruising on the street, towing, or tackling demanding trails.
