Construction & Design:

Fabtech’s Trail Suspension System is built with ruggedness and precision in mind. The heavy-duty link arms use thick-walled steel tubing to withstand extreme off-road stresses without bending or fatigue. Polyurethane bushings reduce noise and vibration while providing long-lasting durability. The dual rate coil springs are engineered specifically for the Jeep JL chassis, delivering a smooth initial ride with progressive stiffness to handle payload and high-speed impacts.

The system’s design preserves factory control arm mounting points, simplifying installation and maintaining proper suspension geometry. The inclusion of a draglink flip kit and reinforced track bar bracket ensures steering components operate within factory parameters, extending their service life even with increased ride height.
