Quick Summary

This two-cap LUXTRKSTO set is described for trailer hubs with a 1.98-inch cap diameter. The caps are zinc-plated carbon steel, and the product description recommends installation with a rubber mallet.

Key Details

Detail Product information and buyer relevance
Quantity Two dust caps.
Outer diameter 1.98 in (50.4 mm); check the hub opening before selecting caps.
Material and finish Carbon steel with zinc plating.
Thickness 0.04 in.
Warranty The product description states a 6-month warranty; check the applicable terms.

Compatibility, Size and Fit

The caps are described as fitting most standard 2,000-3,500 lb trailer hubs, including EZ Lube and standard axle types. The description also names most 4- and 5-lug axles when the cap diameter is 1.98 in. These are broad fit claims, so verify the exact hub opening and axle configuration rather than relying on axle weight or lug count alone.

What to Compare Before Buying

  • Measure or confirm the hub’s cap opening against the 1.98 in outer diameter.
  • Check that the axle and hub configuration matches the stated application.
  • Confirm the selected item is the two-cap quantity.

The description says the cap is slightly larger by design and recommends a rubber mallet for installation. Follow the applicable axle or hub instructions; this recommendation is not a complete installation procedure.

Before You Decide

Confirm the cap diameter, axle and hub fit, and two-piece quantity. Review the applicable installation instructions and warranty terms for the exact item.
