Rock Krawler 3.0" Silverback "NO-LIMITS" Long-Arm Lift Kit for Jeep Gladiator JT delivers the ultimate combination of daily driving comfort and hardcore off-road capability for your Jeep Gladiator JT. Designed to excel both on the street and the trail, this system blends a full high-clearance 4-link front suspension with a high-clearance triangulated 4-link mid-arm rear suspension.

Key Features:

  • Service-Free Adventure Series Joints: Say goodbye to greasing. Our innovative joints isolate harsh vibrations like an OE bushing, allow maximum articulation with high misalignment, and are built to last — resisting wear, chafing, or deformation even in the harshest conditions like mud, sand, snow, and salt.

  • Precision-Engineered Sleeves: Each joint features a steel sleeve that rotates freely on a Teflon-lined inner sleeve, preventing bushing compression and ensuring quiet, long-term performance without maintenance.

  • "No-Limits" Front Sway Bar Links: Designed to work seamlessly with the factory electronic sway bar disconnect found on Rubicon models. Featuring CNC-machined billet aluminum centers and Made-in-USA FK heims — press the button, hit the rocks, and go.

  • Triangulated 4-Link Rear Suspension: Keeps the rear axle perfectly centered, eliminates the need for a rear track bar, reduces suspension bind, and dramatically improves both on-road and off-road ride quality.

  • Adventure-X Mid-Arms: Adjustable upper and lower control arms with Adventure Series joints offer 70 degrees of misalignment, significantly reducing the inherent bind of factory Jeep Gladiator control arms. Easily fine-tune your Gladiator’s caster and pinion angles.

  • Triple and Quad Rate Coil Springs: Triple-rate front coils and quad-rate rear coils deliver a smoother, more controlled ride than factory springs — both on-road and off-road. The coils are engineered with the correct free-length to stay seated during full articulation.

All Rock Krawler JT suspension systems include correction pads to minimize spring bow and track bar geometry correction to perfectly center the axles — enhancing both handling and off-road performance.

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
