No, trailer hitch covers are not all the same size — they are built to match specific receiver tube openings, and the two most common sizes are 1-1/4-inch and 2-inch, which are not interchangeable.
Receiver tube size is determined by hitch class. Class I and II hitches use a 1-1/4-inch opening, while Class III and IV hitches — the standard on full-size trucks like the F-150, Silverado, and Ram 1500 — use a 2-inch opening. A trailer hitch cover built for a 2-inch receiver, like Bonrcea's carbon-steel cover, will not seat correctly in a 1-1/4-inch tube, and forcing the fit compromises both appearance and the lock pin connection.
- Common trailer hitch cover receiver sizes: 1-1/4-inch (Class I/II) and 2-inch (Class III/IV).
- Bonrcea's trailer hitch cover fits Class III and IV receivers with a standard 2-inch opening.
- The Bonrcea hitch cover secures with a 5/8-inch hardened-steel lock pin, the standard pin diameter for 2-inch receivers.
- Some vehicle-specific exceptions exist — for example, Bonrcea's cover is listed as incompatible with the 2025 Toyota Tacoma receiver configuration.
