Axle Dimensions Explained:

Accurate measurements are essential for optimal performance. The hub-face-to-hub-face dimension measures the distance from the base of one wheel stud to the base on the opposite side when hubs are mounted (sold separately). The spring-center-to-spring-center measurement approximates your trailer’s width, defined by the positioning of the loose spring seats, offering flexibility in configuring your suspension system.

Application:

This axle beam is perfect for replacing a trailer axle or fabricating a custom suspension for trailers that demand reliable performance and consistent tire contact. Ensure you consider your trailer’s capacity, wheel bolt pattern, brake type, and desired hub-face measurement to achieve the ideal setup.
