Compatibility and fit at a glance

These hubs are designed to fit Trojan Duratorque and beam axles and should fit a wide range of NZ manufactured trailer axles. When selecting your configuration, match the wheel stud pattern to your rims (5 studs with 4 1/4" or 4 1/2" PCD, with 7/16" or 1/2" stud widths) and decide between integral or bolt-on discs.
