Sizes: see table below
- A triangulated 4-link locates a solid axle with two lower links and two angled upper links; the triangulation locates it sideways so no panhard bar is needed (Axial).
- Axial says it moves the axle in a more linear path with less sway, steer and torque twist than a 3-link. Builder rules of thumb on NC4x4: at least 6 in of vertical link separation at the axle and 40 deg or more of triangulation for lateral control.

Upper vs lower links  uppers shorter so anti-squat falls with droop  NC4x4 forum
