Rock Krawler JT45X2LA-DTR 4.5 Inch X-Factor X2 Trail Runner Long Arm Suspension System

The Rock Krawler JT45X2LA-DTR is a 4.5-inch X-Factor X2 Trail Runner Long Arm Suspension System engineered specifically for the Jeep Gladiator JT diesel platform. This comprehensive long arm system delivers a full coilover setup at all four corners, purpose-built for serious rock crawling while maintaining excellent on-road manners.

At the heart of the system is Rock Krawler's proven X2 geometry, featuring an independent 3-link design front and rear for maximum articulation and off-road performance. The Trail Runner configuration runs coilovers front and rear using RRD 2.625-inch remote reservoir coilover shocks, delivering exceptional wheel travel and tuned ride quality both on the street and on the trail.

The X-Factor X2 system's proprietary geometry enhances rear instant center and roll center behavior for stable, predictable handling under all load conditions — whether driving highways, towing, or pushing through technical rock terrain. The Adventure Series joint design absorbs vibration similar to OEM bushings while eliminating grease maintenance points, making this system as trail-ready as it is daily-driver friendly.
