Rock Krawler JL35X2PNL-2TR 3.5 Inch X Factor X2 Pro No Limits Trail Runner Long Arm Suspension System

The Rock Krawler JL35X2PNL-2TR is a 3.5-inch X Factor X2 Pro "No Limits" Trail Runner Long Arm Suspension System built for serious off-road performance. This 2-door configuration features a front and rear coilover setup — the defining characteristic of the Trail Runner series — delivering an additional level of ride tunability beyond a standard coil spring system.

At the core of this kit is Rock Krawler's independent 3-link long arm design front and rear, engineered for maximum suspension articulation and ground clearance. X2 rear suspension geometry provides adjustable anti-squat with enhanced rear instant center and roll center management, keeping the chassis composed on and off the trail. High clearance axle mounts deliver up to 4.5 inches of additional ground clearance under the rear axle compared to stock.
