5th Wheel to Gooseneck Adapter Fits Standard 5th Wheel Rails - Heavy

In this review of the 5th Wheel to Gooseneck Adapter, the bottom line is simple: this is a straightforward, heavy-duty solution for anyone who already has industry-standard 5th wheel rails and needs gooseneck towing capability. The reviewer found it best for contractors, farmers, and RV owners who tow heavy trailers and want a durable, easy-to-install plate that converts existing 5th wheel rails into a functional gooseneck hitch. The single biggest reason to buy is its combination of a 30,000 lb gross trailer weight rating and a universal fit that removes the need to change the existing rail hardware.

Key Features

• Heavy-duty construction: Built from heavy steel to provide a 30,000 lb GTW rating and reliable strength for demanding towing jobs.
• High vertical load capacity: Rated for up to 6,500 lb max vertical load so it can handle heavy tongue weights without compromising stability.
• Universal fit: Designed to fit all industrial standard 5th wheel rails, making conversion to a gooseneck simple without rail replacement.
• 3 in offset design: Offset ball can be mounted in either direction to suit long-bed or short-bed trucks for better trailer balance.
• Easy installation: Ships with the necessary pins and installs by dropping into the rails and securing the provided pins for a quick changeover.
• Industrial-grade finish: Powder coat protection helps resist rust and corrosion for long-term use in harsh conditions.

Who It's For

This adapter is ideal for users who already have standard 5th wheel rails and need gooseneck capability without swapping hitches or rails, including farmers hauling heavy equipment, contractors moving dump trailers, and boat owners with gooseneck trailers. It is also suited to truck owners who need a robust, weather-resistant plate rated for high GTW and vertical loads.

Those who should look elsewhere are buyers who need a custom rail fit or an integrated permanent gooseneck installation that alters the bed floor or requires a flush-mounted ball; this product is a rail-mounted adapter intended for reversible conversion and not a permanent in-bed weld-in solution.
