Rock Krawler JT45SB2-TR 4.5 Inch Silverback Stage 2 Trail Runner Long-Arm Coilover Suspension System

The Rock Krawler JT45SB2-TR is a 4.5-inch Silverback Stage 2 Trail Runner long-arm coilover suspension system engineered for the Jeep Gladiator JT. This complete lift kit blends hardcore off-road capability with daily-driver comfort, delivering a full front-and-rear coilover configuration for maximum tuneability at all four corners.

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. This geometry eliminates the rear track bar entirely, keeping the rear axle perfectly centered throughout the suspension cycle, reducing rear suspension bind, and greatly smoothing the highway ride by eliminating the cross-talk of front and rear track bar arrangements.

Trail Runner Stage 2 Coilover Package:

• Front and rear RRD 2.625-inch Remote Reservoir Racing Coilovers — fully adjustable and tunable for on-road comfort and off-road performance
• Fast CD (Compression Dampening) Adjusters included on the Stage 2 Trail Runner coilovers for an elevated level of fine-tuning capability
• Triple-rate front coil springs and quad-rate rear coil springs engineered with proper free-length for maximum articulation while maintaining spring seat contact under extreme flex
• X Factor Series adjustable lower control arms offering up to 90 degrees of total misalignment
• Service-free long arms with Adventure Series joints that isolate road vibration while providing high misalignment capability with zero maintenance
• Coil correction pads to reduce spring bow and track bar geometry correction to perfectly center the axles
• Approximately 4.5 inches of lift over stock height

The Trail Runner configuration features coilover shocks at all four corners, maximizing articulation and off-road performance. Note that rear coilovers are optimized for off-road use and are not ideal for frequent towing or heavy bed loading. Rock Krawler's Silverback Stage 2 Trail Runner system is the foundation for serious off-road builds that still demand exceptional street manners.
