Just because you install 5th wheel brackets and rails in your truck bed does not mean your truck is limited to one type of towing. To give your truck the tools it needs to be the ultimate towing machine, CURT offers a gooseneck adapter for a 5th wheel setup. A 5th wheel / gooseneck plate is essentially a gooseneck hitch that mounts into a set of 5th wheel rails just like a 5th wheel trailer hitch. This allows you to pull both 5th wheel trailers and gooseneck trailers with the same pickup truck. CURT 5th wheel gooseneck hitches feature four pin-and-clip attachment points for a solid installation and quick removal when necessary, giving you full access and full use of your truck bed for hauling other loads. Best of all, our gooseneck adapter plates mount onto all industry standard rails. This particular 5th wheel to gooseneck adapter plate, the Spyder gooseneck, features an impressive gross trailer weight capacity of 25,000 lbs., a tongue weight capacity of 6,250 lbs. and offers a 2-5/16" trailer ball for pulling most types of gooseneck trailers, including livestock trailers, chopper boxes, gravity boxes, industrial equipment haulers, flatbeds and more. CURT 5th wheel gooseneck plates and gooseneck 5th wheel adapters are the ultimate versatility tools in heavy-duty towing. We coat our 5th wheel gooseneck hitches in a black carbide powder coat to ensure that they are highly resistant to rust, scratching and UV damage.

The CURT 16085 Spyder gooseneck hitch is a gooseneck-style trailer hitch designed for heavy-duty towing. It has a gross trailer weight (GTW) capacity of 25,000 lbs and a tongue weight (TW) capacity of 6,250 lbs. The hitch assembly includes a spyder gooseneck, U-bolts, springs, washers, nylock nuts, rail pins and rail pin clips. Base rails are sold separately.
Yes. The CURT 16085 Spyder gooseneck hitch requires base rails, which are sold separately. The hitch assembly is placed into the base rails during installation, and the rail pins are inserted through the rails and gooseneck to secure it.
You will need a torque wrench, ratchet, and socket set. The manual rates the installation as 'Easy' difficulty.
The CURT 16085 includes: 1 spyder gooseneck, 2 U-bolts (M16 x 2, 100), 4 U-bolt springs, 8 flat washers (M16), 4 nylock nuts (M16), 4 rail pins, and 4 rail pin clips. Base rails are not included and must be purchased separately.
Assemble the U-bolts in this order: U-bolt (#2), U-bolt spring (#3), flat washer (#4), flat washer (#4), nylock nut (#5). Thread the nylock nut onto the U-bolt just so the first threads start to protrude from the other side of the nut. Do not fully tighten at this stage.
Place the assembled Spyder gooseneck hitch into the base rails. Insert the four provided rail pins through the rails and gooseneck. Secure each rail pin with a rail pin clip.
The CURT 16085 has a gross trailer weight (GTW) capacity of 25,000 lbs and a tongue weight (TW) capacity of 6,250 lbs. You must never exceed the vehicle manufacturer's recommended towing capacity, even if the hitch capacity is higher.
Wax the hitch after installation and regularly thereafter to add a protective layer over the finish. Use only mild automotive detergent to clean it. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes or polishes or waxes containing abrasives, as these will damage the finish.
Periodic inspections should be performed to ensure all mounting hardware remains tight. This is especially important if a transfer tank is installed.
The CURT 16085 is a Spyder gooseneck hitch with a 25,000 lbs GTW and 6,250 lbs tongue weight capacity. Base rails are sold separately.
No. Base rails are sold separately and must be purchased to complete the installation.
Wax after installation and regularly thereafter. Clean with mild automotive detergent only. Do not use abrasive cleaners, wire brushes, dish detergent, or abrasive waxes or polishes.
