Rock Krawler Silverback Hybrid Arm Upgrade System For Jeep Gladiator JT (GAS)

The Rock Krawler Silverback Upgrade System is the ultimate performance upgrade for your Jeep Gladiator JT. This Designed for serious off-roaders who still drive their Gladiator daily, this system blends high-clearance off-road performance with on-road comfort and precision.

At the heart of this kit is a high-clearance 4-link front suspension and a triangulated 4-link rear setup, providing maximum articulation and control without the bind of traditional track bar setups. The rear triangulation eliminates the rear track bar entirely for smoother highway handling and superior axle centering.

This kit features Rock Krawler's fully service-free long arms with Adventure Series joints. These advanced joints isolate road vibration like an OE bushing, while offering high misalignment capability and long-lasting performance with zero maintenance.

No grease. No noise.

No compromise. The Adventure-X Mid-Arms offer 70 degree of misalignment and fully adjustable upper and lower control arms for precision tuning of your Gladiator's caster and pinion angles.

Whether you're crawling rocks or cruising pavement, you'll notice the difference. When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, in tow or down a trail! Thank you for considering Rock Krawler Suspension.
