GTownWorks Wheel Center Caps 4.88-Inch
Product description
Key points
These GTownWorks wheel center caps are for truck, trailer, RV, and SUV wheels with a 4.88-inch center bore. The set includes four push-through caps made from carbon steel with a chrome-silver finish.
Their job is practical as well as cosmetic: they cover the wheel hub opening to help keep out dirt, moisture, and road debris. The chrome-plated finish is described as corrosion-resistant, including against road salt, and should be straightforward to wipe clean.
Keep in mind that the fit is limited to a 4.88-inch center bore. The caps are not a universal-size replacement, so matching the opening matters more than the vehicle label.
How it fits
Each cap measures 124 mm (4.88 inches) in diameter, with an overall height of 122 mm (4.8 inches). The product is designed to push through the back of the wheel and seat in the matching opening, a small flange at the rear helps keep it from passing through.
Before choosing, measure the wheel’s center bore with a digital caliper if its size is uncertain. A wheel that looks close by eye may still have an opening that is too large or too small. It suits you if your wheel has the specified 4.88-inch pilot diameter and you want a fitted cover rather than leaving the hub exposed. You may want to skip it if your wheel uses another center-bore size or you need a cap that attaches in a different way.
Tips for day-to-day use
Installation is intended to be simple: push each cap into the center of the rim from the back of the wheel. For example, while replacing a missing cover on a trailer wheel, check the opening first, then press the cap into place rather than choosing by the vehicle name alone. The snug, correctly sized fit is the key part of the process.
The covered opening can help reduce the amount of grit and moisture reaching the hub area, while the chrome-silver surface gives the wheel a cleaner, more finished look. Compared with leaving the center open, this adds a physical cover, compared with a more elaborate wheel upgrade, it focuses on the hub opening rather than changing the whole rim. From the way it is set up, accurate sizing is the main thing to get right.
Practical doubts
How many caps come in the set? It includes four replacement center caps.
Can I install them from the front of the wheel? The described installation is push-through: the cap is pushed into the wheel from the back and seats in the center opening.
Will they fit a wheel with a different center bore? The listed fit is for a 4.88-inch center bore only. Measure the opening before ordering if you are unsure.
Is it worth it?
These caps make sense when the wheel opening measures 4.88 inches and you want a straightforward way to cover the hub while refreshing the wheel’s appearance. The four-piece set, carbon-steel construction, and chrome-silver finish suit a replacement job where fit and basic coverage are the priorities. If your opening is a different size, or you are looking for a broader wheel change rather than hub covers, this set is not the right match.
