Rock Krawler JT30OX-D 3.0 Inch Overland X Mid-Arm Suspension Lift Kit Diesel

The Rock Krawler JT30OX-D is a 3.0-inch Overland X Mid-Arm Suspension Lift Kit purpose-built for Jeep Gladiator JT diesel models. Engineered for drivers who demand real off-road performance without sacrificing daily drivability, the Overland X system delivers a complete bolt-in solution with heavy-payload coil spring tuning, full geometry correction, and Rock Krawler's proven service-free control arm joints.

Overland-Tuned Coil Spring Package:

• Triple Rate front coil springs and Quad Rate rear coil springs provide 3.0 inches of lift while delivering on-road comfort that rivals or exceeds the factory setup
• Rear coils are specifically valved to handle significant static payloads — ideal for overlanding, bed-loaded builds, and trailer towing applications
• Coils are built to the proper free-length for maximum off-road articulation and stay firmly seated in the coil bucket throughout the suspension travel range

Geometry Correction & Control Arms:

• Includes front and rear spring correction pads to minimize the spring bow inherent in the factory Gladiator setup
• Front and rear track bar geometry corrections precisely center both axles for zero compromise in on-road handling
• Adventure Series control arm joints are 100% service-free and deliver up to 70 degrees of misalignment, dramatically reducing the bind found in factory JT control arms
• Fully adjustable upper and lower control arms allow precision tuning of caster and pinion angle front and rear

Diesel-Specific Engineering:

• Coil spring rates and geometry are calibrated for the added weight of the Jeep Gladiator EcoDiesel engine
• Designed to maintain proper front-to-rear rake and ride height specific to diesel-equipped JT platforms

Additional Kit Features:

• Complete bolt-in installation — no cutting or welding required for the base system
• Front and rear spring leveling pads included
• Rear spring seats included
• Lifetime warranty on all hard parts

The Rock Krawler JT30OX-D Overland X lift kit is the ideal upgrade for Gladiator diesel owners who want a trail-ready suspension system that excels equally on the highway and the trail.
