Rock Krawler JT45AX2LA-TR 4.5 Inch Adventure-X2 Trail Runner Long Arm Suspension System

The Rock Krawler JT45AX2LA-TR is the 4.5-inch Adventure-X2 Trail Runner Long Arm Suspension System, engineered to deliver the ultimate balance between daily-driver comfort and hardcore off-road performance. The Trail Runner designation means coilover shocks are fitted at all four corners, maximizing suspension tunability and off-road capability while remaining well-sorted for street use.

At the heart of this system is a full high-clearance 4-link long arm front suspension paired with a high-clearance independent 3-link long arm rear suspension, combining superior geometry with maximum ground clearance. The X2 rear suspension design features enhanced rear instant centers and roll centers, delivering the smoothest-riding 3-link independent rear suspension available for the platform. High-clearance rear axle mounts provide 4.5 inches of additional ground clearance under the rear axle compared to stock.

Key Features:

• Trail Runner coilover configuration — 2-5/8" RRD Racing Coilovers with remote reservoirs at all four corners for maximum adjustability and off-road performance
• Adventure Series service-free joints — isolate harsh road vibrations equivalent to OE bushings, with high-misalignment capability and a steel sleeve rotating on a Teflon-lined inner sleeve to prevent wear; zero maintenance, zero grease required
• Engineered clamping design — the joint sleeve acts as a buffer between the bracket's clamping force, preventing bushing compression during installation for long-lasting, noise-free performance
• Full high-clearance 4-link front suspension with long arm geometry for improved articulation and on-road handling
• Independent high-clearance 3-link rear suspension with X2 geometry for enhanced rear instant center and roll center performance
• 4.5" rear axle ground clearance gain from the X2 high-clearance axle bracket system
• Rear upper shock relocation brackets to preserve full shock and suspension travel
• All necessary hardware and detailed installation instructions included

The Adventure-X2 Trail Runner system is designed and manufactured in the USA, reflecting Rock Krawler's commitment to precision engineering and real-world proven performance. Whether navigating rocky trails or cruising the highway, this long arm system provides a premium suspension foundation for serious Jeep Gladiator builds.
