Quick Summary

These LUXTRKSTO trailer hub dust caps have a stated 1.98-inch outside diameter and are described for standard 2,000 to 3,500 lb trailer hubs, including EZ Lube and standard axles. The package listing also specifies two replacement rubber plugs.

Key Details

Detail Product information and buyer relevance
Outside diameter 1.98 inches (50.4 mm); check the hub opening against this measurement.
Stated fit range Described for most standard 2,000 to 3,500 lb trailer wheel hubs, including EZ Lube and standard axle types.
Lug configuration Described as fitting most 4-lug and 5-lug axles when the cap diameter is 1.98 inches.
Material and thickness High-carbon steel with a stated thickness of 0.05 inch.
Surface Zinc plated.

Compatibility, Size and Fit

The stated fit is not universal: the description says “most” hubs in the listed range. Confirm the hub’s cap opening measures 1.98 inches and check the axle and hub configuration before choosing these caps. The title also identifies Dexter EZ Lube applications, but the listed size and exact hub fit should still be checked.

What Is Included

The title specifies two dust caps and two extra rubber plugs. The plugs are described as replacements for the cap plugs.

Setup and Correct Use

The product description says the cap is slightly oversized by design, recommends a rubber mallet for installation, and suggests grinding the outside edge to a taper to make installation easier. Confirm the fit and follow the applicable instructions for the specific trailer hub before installation.

Before You Decide

Check the 1.98-inch outside diameter against the hub, confirm the axle and hub configuration, and verify that the listed two caps and two replacement plugs match the package you need.
