4.90" Center Caps

When it comes to the center hole of a trailer rim, it is to some extent a standardized measurement. For example a 4 lug trailer rim, will generally have a 2.80 in center bore, where as a 5 lug wheel generally measures 3.19 in or 3.30 in. Getting into the larger sized trailer wheels, a 6 lug commonly has a measurement of 4.25 in or 4.28 in, and the center bore of an 8 bolt rim is most often either 4.90 in or 5.12 in. 

Our center caps are available in chrome-plated steel and plastic, or stainless steel. We even offer black center caps for those tough looking aluminum trailer wheels. Typically, the majority of our caps are compatible with standard axles or axles with E-Z lube, by simply removing a replaceable plug.
