Rock Krawler JT45SB2-CS 4.5 Inch Silverback Coil Over Long-Arm Suspension System

The Rock Krawler JT45SB2-CS 4.5 Inch Silverback Coil Over System is a premium long-arm suspension lift kit engineered for the Jeep Gladiator JT. This system is designed for serious off-road enthusiasts who also use their Gladiator as a daily driver, delivering high-clearance trail performance without sacrificing on-road comfort or precision handling.

At the core of the Silverback system is a full high-clearance 4-link long-arm front suspension paired with a triangulated 4-link rear assembly. The triangulated rear setup keeps the rear axle perfectly centered throughout the suspension travel cycle, eliminates the need for a rear track bar, removes rear suspension bind, and significantly smooths out highway ride by eliminating cross-talk between front and rear track bar geometry.

Key Features:

• 4.5 inches of lift for increased ground clearance and larger tire fitment
• High-clearance 4-link long-arm front suspension with maximum articulation and geometry correction
• Triangulated 4-link rear assembly — eliminates rear track bar for superior axle centering and reduced suspension bind
• Adventure-X Mid-Arms with adjustable upper and lower control arms offering 70 degrees of misalignment for precision caster and pinion angle tuning
• Service-free long arms with Adventure Series joints that isolate road vibration, require zero greasing, and deliver long-lasting performance
• Triple-rate front coil springs and quad-rate rear coil springs engineered with proper free-length for articulation while maintaining spring seat contact under extreme flex
• Coil Over shock configuration for an additional level of ride tuneability and enhanced off-road performance
• Coil correction pads included to reduce spring bow inherent in the factory setup
• Track bar geometry correction included to perfectly center axles front and rear

The coil over configuration of the Silverback CS system adds a further dimension of tunability compared to standard coil spring setups, allowing owners to dial in ride height, damping, and overall performance to their specific needs — whether on the street, towing, or on the trail. All components are manufactured by Rock Krawler Suspension in the USA.
