Choose Your Axle Size (Hub Face / Spring Center)
Select the hub face (HF) and spring center (SC) measurements that match your trailer frame and suspension setup for proper alignment, tire clearance, and safe towing performance.
- 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.
