Technical Specifications and Features

The Fabtech 8in Rad Arm System is engineered with precision and includes several key features that set it apart. One unique aspect is Fabtech's extended length Track Bar, which is 4in longer than stock and offset to the driver side, featuring a 1/4in thick steel mounting bracket. This design helps keep the Track Bar and Draglink closer to parallel, reducing push in the steering and improving overall steering performance. Additionally, the system includes the massive Dirt Logic 4.0 Resi Coilover Conversion, providing outstanding damping capacity for off-road adventures while maintaining a quality on-road ride. The Coilover bolts in place of the factory coil spring without removing the bucket, and the 4in diameter aluminum remote reservoir mounts horizontally above for full compression travel with oversized tires.
  • Extended length Track Bar for improved steering performance
  • Dirt Logic 4.0 Resi Coilover Conversion for enhanced damping
  • 4in diameter aluminum remote reservoir for full compression travel
