Rock Krawler JT45SB2NL-CS 4.5 Inch Silverback No Limits Long-Arm Coil Over Suspension System

The Rock Krawler JT45SB2NL-CS is a 4.5-inch Silverback "No Limits" Coil Over long-arm suspension system engineered for the Jeep Gladiator JT. This complete system is designed for serious off-road enthusiasts who want maximum trail capability without sacrificing daily drivability.

At the core of the Silverback system is a high-clearance 4-link long-arm front suspension paired with a triangulated 4-link rear assembly, delivering maximum articulation and precise axle control. The triangulated rear design eliminates the need for a rear track bar entirely, keeping the axle perfectly centered throughout the suspension cycle and eliminating rear suspension bind for a noticeably smoother highway ride.

Key Features:

• "No Limits" Front Sway Bar Links — CNC-machined billet aluminum centers with Made-in-USA FK heim joints, engineered to work seamlessly with the factory Rubicon electronic sway bar disconnect for bind-free maximum articulation
• Triple-Rate Front Coil Springs paired with Quad-Rate Rear Coil Springs — engineered with proper free-length to maintain spring seat contact even under extreme flex, while preserving standard JT rear load capacities
• X Factor Series Adjustable Lower Control Arms — offering up to 90 degrees of total misalignment for precision tuning of caster and pinion angles
• Adventure Series Joints — fully service-free, zero-maintenance joints that isolate road vibration while providing high misalignment capability and long-lasting durability
• Coil Correction Pads included to reduce factory spring bow and improve coil geometry
• Track Bar Geometry Correction included front and rear to perfectly center axles and maintain on-road handling precision

The "No Limits" designation reflects this system's compatibility with the factory Rubicon electronic sway bar disconnect — simply press the button and hit the rocks. Whether crawling technical trails or cruising the highway, the Silverback No Limits Coil Over system delivers an exceptional balance of off-road performance and on-road comfort.
