Why Choose ICS Trailers
Hub cap fitment depends on mounting geometry, not appearance alone. ICS Trailers can compare the old cap, bolt-circle measurement, flange size and wheel-end details when the original number is difficult to read.
- The matching gasket and replacement window kit can be identified during the same wheel-end service.
- Interchange numbers help when an older cap carries a different manufacturer marking.
