A 4-stud cast wheel hub fitted with taper roller bearings and 3/8" wheel studs. Supplied complete with nuts and cap for straightforward installation.
Reduced Wheel Play – with taper roller bearing hub
Taper roller bearings use tapered rollers and matching raceways to carry combined radial and axial loads while resisting end float. Correct bearing preload limits lateral movement and keeps the wheel running true.
Significantly tighter wheel running and steadier tracking under load, which helps maintain alignment and reduces wear on tyres and axle components.
Straightforward Fitment – thanks to 4-stud 4" PCD and 3/8" studs
A 4-stud bolt pattern with a 4" pitch circle diameter matches common trailer wheel patterns, and 3/8" studs are already fitted to the hub assembly. Matching the PCD ensures bolt holes line up without modification.
Quick replacement for compatible axles, cutting installation time and avoiding the need to press or adapt studs on site.
Ready-to-Mount Kit – with nuts and cap included
The hub is supplied complete with wheel nuts and a protective cap, so no separate fasteners are required for initial assembly. The cap protects bearings from dirt and water ingress.
Everything needed for a single-unit swap is in the box, reducing parts hunting and getting trailers back on the road faster.
