4 Pack 4.25 in Center Caps Push Through for Trailer Truck RV Wheels

Our review of these 4.25 in center caps finds them best for owners of trailers, trucks or RVs who need a simple, durable replacement hub cap that installs without tools. The biggest reason to buy is straightforward: these caps are made from black carbon steel and are designed to resist rust and moisture while delivering a snug, finished look for wheels with a 4.25 in center bore. If the wheel center hole matches, the set of four offers an inexpensive and practical way to refresh wheel appearance and protect the hub area.

Key Features

• Material: Carbon steel construction with a black finish provides corrosion resistance and weather protection for long service life.
• Exact Fit: Designed to fit a 4.25 in center bore only, ensuring a secure, direct replacement when the measurement matches.
• Dimensions: Measuring 4.25 in diameter excluding the flange and 4.56 in including the flange gives a predictable fit for compatible rims.
• Easy Installation: Push-through back installation lets one person fit the caps quickly without specialized tools.
• Complete Pack: Four caps in the package cover both front and rear wheels for a single-vehicle refresh or for multiple wheels on a trailer.

Who It's For

This product is aimed at trailer, truck and RV owners who already know their wheel center bore measures 4.25 in and want a straightforward, affordable replacement or cosmetic upgrade. It suits DIYers who prefer quick push-through installation and drivers who need corrosion-resistant parts that tolerate wet conditions.

It is not for buyers with nonstandard or unknown center bores; measure the hub bore before purchase. Also consider different styles or stainless options if you want decorative caps or higher-end finish beyond utilitarian black carbon steel.
