Rock Krawler JT30OS-D 3.0 Inch Overland Mid-Arm Suspension Lift Kit for Jeep Gladiator JT Diesel

The Rock Krawler JT30OS-D is a 3.0-inch Overland Series Mid-Arm suspension lift system engineered specifically for diesel-powered Jeep Gladiator JT models. Designed for overlanders and truck owners who carry significant static payloads, this system delivers bolt-in installation with incredible off-road capability and a comfortable on-road ride.

Overland-Optimized Payload Capacity:

Rock Krawler's Overland Systems are purpose-built to carry 500 pounds in the bed area while keeping the vehicle sitting perfectly level under that load — making this kit ideal for truck campers, tool storage, and serious overland builds. The system maintains safe operating range while preserving acceptable tongue weight for trailer towing.

Adventure Series Control Arms:

The adjustable-length high-clearance front lower control arms feature Rock Krawler's 100% service-free Adventure Series joints. These industry-leading joints deliver a total of 70 degrees of misalignment at both the frame and axle connections, dramatically reducing the bind inherent in factory JT control arms for superior articulation and durability.

Triple Rate Front & Quad Rate Rear Coil Springs:

The proprietary multi-rate coil spring design — triple rate up front and quad rate in the rear — provides 3.0 inches of lift, improves on-road ride quality over factory linear-rate springs, and delivers controlled, predictable responses to varied terrain. Springs are built with proper free-length for off-road articulation and stay firmly seated in the coil bucket throughout the suspension's range of travel.

Geometry Correction Included:

All Rock Krawler JT systems include correction pads to minimize the spring bow inherent in the factory setup. Front and rear track bar geometry corrections allow precise axle centering with no compromise in on-road handling.
