The CURT Spyder 5th Wheel Rail Gooseneck Hitch (Part #16090) lets your 5th-wheel-rail-equipped truck tow gooseneck trailers as well. Mounts directly into any industry-standard 5th wheel base rails with a four-pin installation, providing a welded 2-5/16" gooseneck ball on top for coupling gooseneck trailers. Rated to 30,000 lb gross trailer weight / 7,500 lb tongue weight. Ideal for buyers who already own a 5th wheel hitch setup and want to add gooseneck capability without installing a separate gooseneck hitch. Quick removal for full truck bed access. Backed by CURT's limited lifetime warranty.

⭐ 5th Wheel Rails → Gooseneck Ball

Standout versatility benefit: let your existing 5th wheel rail setup tow both 5th wheel AND gooseneck trailers. Meaningful for:

  • Horse trailer owners — many horse trailers are gooseneck
  • Livestock haulers, chopper boxes, gravity boxes — commonly gooseneck
  • Industrial equipment haulers, flatbeds
  • Buyers with mixed towing needs — 5th wheel RV plus gooseneck utility trailer

Note: This is the OPPOSITE of an X5 adapter. X5 adapters (16210/16220/16310) convert gooseneck hitches to 5th wheel rails. Spyder converts 5th wheel rails to a gooseneck ball.

⭐ Four-Pin Installation / Quick Removal

Standout install benefit: four-pin attachment points for a solid installation and quick removal when necessary. Meaningful for:

  • Full truck bed access restored when not towing gooseneck (pull the four pins, lift out)
  • Fast swap between 5th wheel and gooseneck towing — remove Spyder, install 5th wheel hitch, ready to tow different trailer type

⚠️ 40K Base Rails Required for Full 30K Capacity

Important sizing note: To reach the Spyder's full 30,000 lb GTW capacity, 40K-rated base rails are required. Standard 25K base rails will cap the Spyder at 25K.
