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

The Rock Krawler JT30AX2LA-DTR is a 3.0-inch Adventure-X2 Trail Runner Long Arm Suspension System engineered to deliver the ideal balance between daily-driver comfort and hardcore off-road performance. The Trail Runner configuration features coilover shocks at all four corners, maximizing suspension adjustability and off-road capability while maintaining excellent street manners.

At the heart of this system is Rock Krawler's proven Adventure-X2 suspension geometry, combining a full high-clearance 4-link long arm front suspension with a high-clearance independent 3-link rear long arm suspension. The X2 rear geometry features enhanced rear instant centers and rear roll centers for a smooth, controlled ride whether you're rock crawling or cruising the highway.

Rock Krawler's Adventure Series joint technology isolates road vibrations like an OE bushing while providing high misalignment capacity. The engineered sleeve design ensures that tightening the control arm hardware does not compress the bushing material, resulting in a long-lasting, rattle-free joint that never needs maintenance. This long arm system is built for Jeep Gladiator JT owners who demand the best in both on-road refinement and off-road dominance.
