Rock Krawler JT30SB2-S1 3.0 Inch Silverback Long-Arm Suspension System Stage 1

The Rock Krawler JT30SB2-S1 is a 3.0-inch Silverback long-arm suspension lift system engineered for the Jeep Gladiator JT. This Stage 1 kit delivers a complete suspension overhaul that balances serious off-road capability with daily-driver comfort, making it one of the most versatile lift systems available for the JT platform.

At the core of the Silverback design is a high-clearance 4-link front suspension paired with a high-clearance triangulated 4-link mid-arm rear suspension. This geometry eliminates the bind found in factory-style track bar setups and provides maximum articulation and axle control both on the trail and on the highway.

Key Features:

• 3.0-inch lift over stock ride height
• High-clearance 4-link front and triangulated 4-link rear suspension design
• Adventure-X mid-arms with adjustable upper and lower control arms — up to 70 degrees of misalignment when paired with Adventure Series joints
• Triple-rate front coil springs and quad-rate rear coil springs engineered for optimal free-length articulation and spring seat retention under extreme flex
• Maintenance-free, grease-free joint design for long-term durability
• Includes coil correction pads to reduce spring bow
• Front and rear track bar geometry correction brackets for precise axle centering
• Triangulated rear design eliminates the rear track bar entirely, reducing highway cross-talk and improving straight-line stability
• Stage 1 configuration — springs, control arms, and geometry correction hardware included

The Silverback system's Adventure-X arms offer extensive adjustability, allowing precise tuning of caster and pinion angle both front and rear. The multi-rate coil spring package delivers on-road ride quality that competes with OEM comfort while maintaining the articulation and durability demanded on the rocks. All hardware and geometry correction components needed to properly center the axles are included in the kit.
