B&W Gooseneck Ball Gap Cover — Black Rubber Low-Profile Seal to Protect Hitch

The B&W GNXA1715 is a heavy-duty black rubber cap designed to seal the gooseneck ball gap when not in use, protecting the hitch area from dirt and moisture.

This compact, utilitarian cover slips into the gooseneck ball gap to keep road grime, water, and debris out of the hitch pocket. Made to fit B&W gooseneck installations, the GNXA1715 provides a low-profile barrier that helps preserve hitch components and maintain a clean appearance when the ball is removed.

How does this cover protect my gooseneck hitch?

The rubber composition creates a snug seal in the ball gap to block contaminants and reduce corrosion risk on exposed metal surfaces. Its flexible shape resists splitting and stays seated under vibration and road motion.

• Form-fitting rubber blocks dirt, mud, and road salt.
• Limits water ingress that can accelerate rusting.
• Flexible material absorbs vibration without tearing.
• Low-profile design avoids interference with tonneau covers or bed accessories.

Will this fit my gooseneck ball opening?

The GNXA1715 is engineered for B&W gooseneck systems and matches the standard ball gap dimensions used across their products. It’s intended for the ball cavity rather than universal oversized openings, so verify compatibility with your model before purchase.

• Designed to match B&W gooseneck ball pocket geometry.
• Ideal for standard factory-size gaps, not oversized holes.
• Easy to install by hand—no tools required.
• Remove quickly when you’re ready to hitch up.

How durable is the rubber and how does it stand up to weather?

The material resists cracking from sunlight and repeated flexing, providing season-to-season protection when used as intended. While not indestructible, the cover is formulated to withstand common outdoor conditions encountered in towing environments.

• UV-resistant rubber to reduce sun degradation.
• Flexible in cold temperatures to avoid brittleness.
• Compression-resistant to stay seated under road forces.
• Simple to clean—wipe or spray off road grime.

How easy is it to use during frequent hitching?

The cap installs and removes in seconds, making it practical for users who alternate between towing and uncovered bed use. Its low weight and compact shape mean it won’t rattle or get in the way when stored in the truck.

• Push-fit installation—no clips or fasteners needed.
• Quick removal with finger pull for rapid hookup.
• Compact profile stores easily in the glovebox or tool tray.
• Durable enough for daily use in active towing schedules.

The B&W GNXA1715 is aimed at truck owners and professional haulers who use B&W gooseneck hitches and want a simple, reliable way to keep the hitch pocket clean and protected when the ball is not installed.
