Rock Krawler JT30AX2LA-TR 3.0 Inch Adventure-X2 Trail Runner Long Arm Suspension System

The Rock Krawler JT30AX2LA-TR is the 3.0-inch Adventure-X2 Trail Runner Long Arm Suspension System, engineered to deliver the ultimate balance between daily street driving and hardcore off-road performance. This comprehensive system pairs a full high-clearance 4-link long arm front suspension with a high-clearance independent 3-link rear long arm suspension for maximum capability across any terrain.

The Trail Runner configuration equips all four corners with coilover racing shocks, maximizing off-road capability and tuneability. The Stage 1 Trail Runner System features 2-5/8" RRD Racing Coilovers with Remote Reservoirs front and rear for a well-tuned performance package. Upgrading to the Stage 2 Trail Runner adds Fast Compression Dampening (CD) Adjusters on the coilovers for an even greater level of on-the-fly tuneability.

Key Features:

• Full High-Clearance 4-Link Front Long Arm Suspension paired with an independent 3-link rear long arm for optimized geometry and articulation
• Adventure Series Joints — 100% service-free, maintenance-free joints that isolate road vibrations, provide high misalignment capability, and never require greasing
• Trail Runner Coilover System — front and rear coilover combination with 2-5/8" RRD Racing Coilovers with Remote Reservoirs for maximum off-road performance
• X2 Rear Suspension Geometry with enhanced rear instant center and rear roll center for the smoothest-riding 3-link suspension available
• 4.5 inches of rear ground clearance gain from the X2 axle bracket system over stock
• Heat Shield thermal barrier protection on front control arm joints at the frame, just like OEM
• Rear upper shock relocation brackets ensure no loss of shock or suspension travel
• Track bar geometry corrections front and rear to perfectly center axles and maintain on-road handling
• Spring correction seats and correction pads to reduce factory spring bow
• Supports up to 37"–40" tires depending on trim level and fender configuration

The Adventure Series joint design features a steel sleeve engineered to act as the buffer between bracket clamping force, ensuring the bushing is never compressed during installation. This results in an exceptionally long-lasting joint that is completely noise-free and grease-free for the life of the system.

Rock Krawler engineered this system to be the comprehensive foundation for every adventure — whether cruising the highway, towing, or descending technical trails. All hard parts are backed by Rock Krawler's abuse-proof lifetime warranty.
