TOYOTA 42603-60500 Wheel Hub Center Cap

This genuine TOYOTA OEM wheel hub center cap (part number: 42603-60500, factory designation: ORNAMENT SUB-ASSY, WHEEL HUB) is a premium quality, factory original component designed to aesthetically seal and protect the central bore of alloy wheels.

Function and Importance:

The primary function of the wheel center cap is to protect the wheel hub and axle shaft retaining nut against environmental impacts. It prevents water, mud, dust, and aggressive road de-icing salt from entering the internal parts of the wheel hub, thereby significantly reducing the risk of corrosion at critical fastening points. In addition, it contributes to the vehicle's uniform, factory appearance.
