Rock Krawler JL45AX2LA-4DCS 4.5 Inch Adventure-X2 Long Arm Coilover Suspension System

The Rock Krawler JL45AX2LA-4DCS is the 4.5-inch Adventure-X2 Long Arm Coilover Suspension System designed for the Jeep Wrangler JL 4-Door. This complete front and rear lift system is engineered to deliver an exceptional balance between daily commuter comfort and serious off-road performance, making it one of the most versatile long arm suspension upgrades available for the JL platform.

Adventure-X2 Long Arm System Architecture:

• High Clearance 4-Link Front Suspension — Full long arm 4-link front geometry for improved caster, enhanced axle articulation, and superior on-road stability
• Independent 3-Link Rear Suspension — High clearance independent rear 3-link conversion using X2 rear suspension geometry with enhanced rear instant centers and rear roll centers for the smoothest-riding 3-link setup available
• X2 Axle Bracket System — High clearance axle mounts deliver 4.5 inches of additional ground clearance under the rear axle compared to stock
• Coilover Shock Configuration — Coilover shocks provide an additional level of tuneability, allowing the owner to further enhance ride quality, handling, and off-road performance to their preference
• 100% Service-Free Adventure-X2 Joints — Maintenance-free joints eliminate the need for greasing while providing long-lasting durability and eliminating bind common in factory control arms
• Triple-Rate Coil Springs — All four coils work together to deliver on-road comfort that surpasses OEM linear-rate springs, with proper free-length for full off-road articulation that keeps the coil firmly seated
• Rear Upper Shock Relocation Brackets — Repositioned upper shock mounts ensure no loss of shock travel or suspension travel during the lift conversion
• Geometry Correction Included — System includes front and rear track bar geometry correction brackets to perfectly center both axles and eliminate on-road handling compromise
• OEM-Style Spring Correction Pads — Reduces the spring bow inherent in the factory JL setup for improved ride quality and spring retention

Installation Notes:

• Requires welding of front and rear long arm frame mounts
• Requires removal of OEM frame-side lower and upper front and rear control arm mounts
• Requires removal of OEM axle-side rear lower control arm and track bar mounts
• Requires modification of OEM rear shock mounts and welding of raised rear upper shock mounts
• Requires welding of the new coilover mount on the axle
• Recommend installing limiting straps after final setup to prevent over-extension
• A new front C.V. driveshaft is recommended for front shocks with a maximum extended length greater than 29 inches

The Rock Krawler Adventure-X2 Long Arm Coilover System is purpose-built for Wrangler JL owners who demand a comprehensive suspension solution that performs on the street, on the trail, and under tow — without compromise.
