Measurement Guide: How to Order the Right Size

If building a custom trailer from scratch, simply select your desired width. If replacing an existing axle, you MUST verify the following two dimensions (an allowable error of up to 1 inch is acceptable):

1. Hub Face Distance (HF): Measure from the base of the wheel studs on one side across to the base of the wheel studs on the opposite side (where the wheel meets the hub).

2. Spring Center Distance (SC): Measure from the exact center of the welded leaf spring seat on one side to the center of the spring seat on the other side.
