CURT Spyder 5th Wheel Rail to Gooseneck Adapter Hitch with 2-5/16" Ball

Convert your fifth-wheel base rails into a heavy-duty gooseneck hitch platform with the CURT Spyder 30,000 lbs Gooseneck Adapter Plate. Engineered from heavy-gauge, high-strength welded steel, this plate features a permanently welded 2-5/16-inch trailer ball capable of handling demanding agricultural, commercial, and livestock towing loads.

Heavy towing engineers note, "Utilizing existing 5th-wheel bed rails for gooseneck conversions maximizes truck versatility without requiring additional frame drilling or permanent bed alterations." Finished in a resilient carbide black powder coat, it withstands severe winter salt, road mud, and harsh weather exposure without chipping or rusting.

Frequently Asked Questions

Can I reach the 30,000 lbs GTW rating on standard 5th-wheel base rails?

Standard base rails are typically rated for 16,000 lbs to 20,000 lbs. To safely utilize the full 30,000 lbs towing capacity of the CURT Spyder plate, you must use CURT 40K Heavy-Duty Base Rails (#16205) and custom under-bed brackets.

Is the 2-5/16" gooseneck ball removable?

No. The 2-5/16" trailer ball is welded directly to the main adapter plate structure to maximize shear strength and towing stability under heavy loads.
