Hub face and spring center measurement diagram for trailer axle sizing

  • Hub Face (HF): Measured from the outer face of one hub to the outer face of the opposite hub
  • Spring Center (SC): Measured from the center of one spring seat to the center of the opposite spring seat

Matching the correct hub face and spring center measurements helps ensure proper fender clearance, suspension alignment, wheel positioning, and overall trailer fitment.
