Why Choose ICS Trailers

Hub caps with the same bolt circle can still differ in depth, flange size and wheel-end application. For this shallow 46mm version, compare the removed cap, bolt pattern and overall depth before ordering. ICS Trailers can help identify the correct replacement from old markings, photos or measurements when the original number is unclear.

• Matching gasket, window kit and vent plug references can be checked during the same wheel-end service.
• Interchange numbers help when an equivalent cap carries different manufacturer markings.
