Rock Krawler JL45AXPNL-4TR 4.5-Inch Adventure-X Pro No Limits Trail Runner Long Arm Suspension System

The Rock Krawler JL45AXPNL-4TR is a 4.5-inch Adventure-X Pro "No Limits" Trail Runner Long Arm Suspension System engineered for Jeep Wrangler JL owners who demand a high-performance lift kit capable of excelling both on daily streets and demanding off-road trails.

Adventure-X Pro Platform:

The Adventure-X Pro system pairs a full high-clearance 4-link long arm front suspension with a high-clearance independent 3-link long arm rear suspension, delivering an optimal balance of on-road ride quality and serious off-road articulation. The "PRO" designation means the system is equipped with 4 billet aluminum CNC-machined, service-free lower control arms in long arm length — offering maximum strength and a maintenance-free ownership experience.

"No Limits" Sway Bar Link Technology:

The "No Limits" designation refers to the inclusion of specially designed front sway bar links built to work seamlessly with the factory electronic sway bar disconnect system found on Rubicon models. These links feature factory-sized hardware, a CNC-machined billet aluminum center section, and Made-in-USA FK Bearing heim joints — allowing Rubicon owners to press the button and hit the rocks without compromising full articulation.

Trail Runner Coilover Package:

The Trail Runner configuration features 2.625-inch coilover shocks at all four corners — front and rear — providing a complete, fully tunable suspension platform. Coilovers allow owners to fine-tune ride quality, handling, and off-road performance to their specific needs.
