The Rock Krawler JL45AXPNL-392TR is a 4.5-inch Adventure-X Pro "No Limits" Trail Runner Long Arm Suspension System engineered specifically for the Jeep Wrangler JL 392 platform. Built to strike the ultimate balance between daily driver comfort and hardcore off-road performance, this system delivers premium components, service-free engineering, and precision geometry in a complete long arm package.

Adventure-X PRO Long Arm System:

• PRO-Grade Billet Lower Control Arms: Features 4 CNC machined billet aluminum service-free lower control arms in a long arm length — providing exceptional strength without routine maintenance
• 4-Link Front / 3-Link Rear Configuration: High clearance 4-link front suspension paired with a high clearance independent 3-link rear suspension for maximum articulation and trail capability
• "No Limits" Sway Bar Links: Front sway bar links are specifically designed to work with the factory electronic sway bar disconnect found on Rubicon models — simply press the button and hit the rocks
• 392-Specific Triple Rate Coil Springs: Heavier-rate coil springs engineered to account for the added weight of the 392 cubic inch V8 engine while delivering 4.5 inches of lift over the factory ride height
• Adventure Series Joints: 100% service-free joints isolate harsh road vibrations and feature high misalignment capability with a Teflon-lined inner sleeve for long-lasting, bind-free performance
• Correction Pads Included: Spring correction pads reduce the factory spring bow, improving coil spring seating and ride quality
• Track Bar Geometry Corrections: Front and rear track bar corrections ensure the axles are perfectly centered for no compromise in on-road handling
• Trail Runner Stage Configuration: Designed as a Trail Runner system for serious off-road use with high axle travel and suspension articulation

System Highlights:

• Complete bolt-in long arm suspension system
• Abuse-proof lifetime warranty on all hard parts (control arms, track bars, brackets)
• Joint housings covered by a 10-year warranty; coil springs by a 5-year warranty
• Designed, tested, and manufactured in the USA
