Custom axle fitment depends on accurate measurements. Hub face, spring center spacing, spring orientation, and hub bolt pattern all need to match the trailer before production.
- Hub Face Check: Confirm 57.75" hub face is correct for the trailer.
- Spring Center Check: Confirm 44.75" spring center spacing before production.
- Bolt Pattern Check: Confirm your wheels use a 5 on 5-1/2" bolt pattern before ordering.
