Rock Krawler JL45AX2NL-2TR 4.5 Inch Adventure-X No Limits Trail Runner Long Arm Suspension System

The Rock Krawler JL45AX2NL-2TR is a 4.5-inch Adventure-X "No Limits" Trail Runner Long Arm Suspension System engineered for the 2-door Jeep Wrangler JL. Designed and manufactured in the USA, this complete long arm lift system delivers the ideal balance between daily driving comfort and serious off-road performance, featuring 2.625-inch coilover shocks front and rear for an aggressive, capable setup.

The Adventure-X platform combines a full high-clearance 4-link long arm front suspension with a high-clearance independent 3-link rear suspension, giving you superior articulation and geometry over stock without sacrificing on-road manners. The rear system utilizes Rock Krawler's proven independent 3-link conversion with X2 rear suspension geometry, including enhanced rear instant centers and rear roll centers for optimized handling dynamics.

The "No Limits" designation refers to the inclusion of specially designed front sway bar links compatible with the factory electronic sway bar disconnect feature found on Rubicon models, allowing full articulation at the push of a button. These sway bar links feature factory-sized hardware, a CNC-machined billet aluminum center section, and Made-in-USA heim joints from FK Bearing.
