GTOWNWORKS Trailer & RV Hub Center Caps 2.22in Chrome — 4-Pack Open-End EZ-Lube, Snap-In

These caps replace lost or damaged push-through center covers on trailers and recreational vehicles, offering a corrosion-resistant, waterproof finish that snaps into place for quick servicing. Made from shiny chrome-plated plastic, the set of four gives a factory-like appearance while protecting the grease port and spindle from dirt and moisture. Exact dimensions are provided so you can confirm fit before purchase.

How do I confirm these caps will fit my hub?

Measure the opening on your existing hub cover with digital calipers and compare to the listed dimensions. The caps are designed to replace most top plug-style push-through center covers, but verifying size prevents returns.

• Outside diameter: 56.5 mm (2.22 in)
• Inside clip diameter: 47.4 mm (1.87 in)
• Clip length: 3.22 mm (0.13 in)
• Overall height: 13.45 mm (0.53 in)

What materials and durability can I expect?

The caps are manufactured from chrome-plated plastic that resists corrosion and stands up to road grime and moisture. While lighter than metal caps, the plated finish preserves a clean, chrome look and protects the underlying wheel hub area.

• Shiny chrome-plated plastic construction
• Waterproof and corrosion-resistant surface
• Durable for typical trailer and RV use
• Sold as a set of four for full-axle replacement

How easy is installation and periodic servicing?

Installation is a simple snap-in operation that replaces push-on hubcaps without tools in most cases. The open-end design allows you to access the EZ-lube fitting quickly for routine greasing without removing the entire hub cover.

• Direct snap-in installation — no special tools required
• Open-end/EZ-lube access for quick greasing
• Removable for periodic inspection and maintenance
• Designed to match common top plug removal style hubs

What should I watch for when ordering replacements?

Check the source of your original caps and measure the hub opening; although these caps fit many top plug-style hubs, cross-brand variations exist. If your original caps came from another manufacturer, confirm the dimensions to ensure a secure clip fit.

• Measure hub opening with calipers prior to ordering
• Compatible with most top plug remove push-through caps
• Not guaranteed to fit every brand — compare dimensions
• Set includes four caps for two-wheel axles or one axle replacement
