We've discovered that the most important measurement in making sure the replacement disc hubs fit correctly on your trailer is dimension E. If we don't get this right, we find that the calipers don't align either side of the rotor face.
As shown above, ALKO disc hubs measure 11.5mm. ALKO also tell us that the measurement from the bearing cup machining to rotor face is critical (in this case, as above, 36mm.)
