Rock Krawler JT30SB2NL-TR 3.0 Inch Silverback No Limits Trail Runner Stage 2 Long-Arm Suspension Lift System

The Rock Krawler JT30SB2NL-TR is the 3.0 Inch Silverback "No Limits" Trail Runner Stage 2 long-arm suspension lift system — a premium coilover-based solution engineered for the Jeep Gladiator JT that bridges the gap between daily driver comfort and hardcore off-road performance.

At the core of the Silverback design is a high-clearance 4-link long-arm front suspension paired with a high-clearance triangulated 4-link mid-arm rear suspension. The triangulated rear setup eliminates the rear track bar entirely, keeping the axle perfectly centered throughout the suspension cycle, reducing bind, and delivering noticeably smoother highway handling.

The "No Limits" front sway bar links are purpose-built for use with the factory electronic sway bar disconnect found on Rubicon models. Featuring CNC-machined billet aluminum centers and Made-in-USA FK heim joints, they allow full use of the factory disconnect at the press of a button.

The Adventure-X mid-arms feature adjustable upper and lower control arms offering up to 70 degrees of total misalignment when paired with Adventure Series joints at the frame and axle connections. This wide range of adjustability allows precise tuning of caster and pinion angle both front and rear, while the service-free joint design eliminates grease points entirely.

Ride quality is managed by triple-rate front coil springs and quad-rate rear coil springs, engineered with proper free-length for articulation while staying firmly seated in the coil buckets. Coil correction pads are included to reduce spring bow and improve geometry.

As a Trail Runner Stage 2 system, this kit features coilover shocks at all four corners for maximum tunability. The Stage 2 configuration upgrades the 2 5/8" RRD Racing Coilovers with Remote Reservoirs to include Fast CD (Compression Dampening) Adjusters, providing an even greater level of on-the-fly tuning capability for ride, handling, and off-road performance.
