Compatibility, Size and Fit
The stated fit is limited to a 1.980-inch inner-diameter hub bore. The axle rating does not replace checking the bore size: verify both measurements for the trailer. The description identifies boat, RV and utility trailers as intended applications, but does not name specific trailer models.
What Is Included
The package includes two trailer hub protectors with rubber dust caps. The number of dust caps is not specified. The description recommends two orders for fully equipping a trailer, but does not specify the number needed for a particular trailer configuration.
Before You Decide
Measure the hub bore with a caliper, confirm the axle rating is within range, and check the package quantity against your replacement needs. If using the lubrication feature, confirm you have a standard grease gun available.
