This is a complete replacement kit for an idler (non-brake) trailer hub. It fits trailer axles rated 5,200 to 7,000 lb that use an 8 on 6.5" bolt circle. The hub comes with 1/2" studs.
The hub uses a 25580 inner bearing and a 14125A outer bearing. The 25520 and 14276 races are already installed. One kit services one hub, so a full axle needs two kits.
Check the bearing numbers stamped on your existing components and verify the seal size before ordering.
