Important Fitment Note:
This kit is intended for one compatible wheel end using a 395S inner bearing, 387A outer bearing, 3.12-inch × 4.506-inch oil seal and 4-inch oil cap. Before ordering, compare the existing hub number, bearing numbers, spindle bearing surfaces, seal dimensions, oil-cap diameter and complete axle specifications. A trailer’s stated 10,000 lb axle capacity by itself is not enough to confirm fitment.
