Why Choose ICS Trailers

Wheel-end washers can be easy to confuse when their overall size is close, so the 88mm ID, 127mm OD and 6mm thickness are worth checking against the removed part. If old markings are still visible, ICS Trailers can also compare those numbers with the supported replacement references and surrounding axle hardware.

  • Check the matching spindle nut arrangement during the same wheel-end repair.
  • Photos and measurements can help narrow down similar Pro-Par components.
