What "breaks" exactly...???
The weak point in a perentie 6x6 (rear) axle is the 1.24" 24 spline halfshafts. Which can easily be upgraded to 1.5" 35 spline.
The front ring and pinion was also a weak point during the trials until they made a special upgraded version.
If you are breaking a perentie 6x6 drivetrain doing hill starts on bitumen then I would question your driving skills.
