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, wheel positioning, tire clearance, and safe towing performance.

85″ Hub Face / 70″ Spring Center – Commonly fits trailers with a 72″ wide frame.
89″ Hub Face / 74″ Spring Center – Commonly fits trailers with a 76″ wide frame.
95″ Hub Face / 80″ Spring Center – Commonly fits trailers with a 82″ wide frame.
Important: Always measure your existing axle before ordering. Do not select an axle based solely on trailer frame width, deck width, or fender spacing.
