The Rago Fabrication Hi-Lift Jack Mounts for the Toyota Bed Rail System were designed to mount a Hi-Lift Jack using the the Toyota Bed Rail System.
The mounts are CAD designed, CNC cut, CNC bent, and welded by Rago Fabrication. They come with high torque knobs. Rago Fabrication designed and made the knobs in house with 1/2 inch bolts that are welded internally. They will never break away from over tightening like the plastic knobs are known for.
