Trailer hubs should be matched by measurements and internal bearing requirements, not only by the axle weight rating. Before ordering, confirm the full hub stack so the hub, spindle, bearings, seal, and wheel all match correctly.
Compatibility: Designed for compatible 3,500 lb trailer axle applications using the correct spindle, bearing, seal, and 5 on 5.5" wheel bolt pattern.
Vehicle / System Fit: Trailer idler hub position where no brake drum is used.
Installation Notes: Verify bearings, races, grease seal, dust cap, lug nuts, and wheel compatibility before installation. Bearings, seals, caps, and lug nuts are not included unless separately stated.
Performance Insight: A properly matched idler hub supports the wheel assembly and allows smooth rotation on the spindle. Correct bearing and seal matching is critical for safe trailer service.
