This Trail suspension system for the 4 Door Jeep JL is engineered to deliver balanced performance for drivers who demand serious offroad capability without sacrificing daily driving comfort. Designed to handle rock crawling, aggressive trail use, and overland travel, the system is carefully tuned with rear dual rate coil springs and matched shock valving to provide a smooth, compliant on-road ride.
The suspension is built as a complete short arm system that utilizes the factory control arm mounting points for a straightforward installation. Fabtech’s heavy duty lower link arms are manufactured from 1.75″ OD, .250″ thick wall steel tubing and are engineered to withstand harsh offroad abuse without bending. Large polyurethane bushings combined with Fabtech’s proven 5 Ton Joint® deliver long service life, quiet operation, and excellent articulation.
The coilover conversion is supported by heavy duty 1/4″ thick steel bracketry that securely mounts to the factory coil spring buckets and frame. Fabtech’s Dirt Logic 2.5 Coilovers feature an all stainless steel body for unmatched corrosion resistance and provide a significant improvement in ride quality over traditional coil spring and shock setups. This upgrade enhances suspension control, comfort, and confidence both on-road and offroad.
Steering geometry is properly corrected for the increased ride height through a heavy duty draglink flip system and reinforced track bar brackets. This design maintains factory steering angles, allows full articulation without binding, and avoids adding stress to the steering box. Rear suspension geometry is equally refined to maintain proper axle centering and factory roll center characteristics.
Every component in this system is engineered to work together as a complete package, resulting in increased wheel travel, predictable handling, and long-term reliability. This makes it an excellent choice for Jeep owners who want a capable trail-ready suspension with refined street manners.
