Product Information:
The products 205ST30K and 205ST45K are gooseneck hitches for a semi-tractor. Class 6, 7, & 8 semi-tractors have 34 inch wide frames (a few semi-tractors in the 1980's were made with 33 inch frames and will work by using ¼” spacers or washers). These also work on Cab & Chassis. Some models of Dodge, Ford & GM truck, Cab & Chassis require a 2 inch taller version to clear exhaust or angle braces. They set 2 inches above the frame and the part number ends with a -T.
The 2-5/16 inch standard gooseneck ball is released by turning a handle 90 degrees, and can be turned over for clearance so you can tow with your 5th wheel hitch.
Other gooseneck ball options are available such as a 2-5/16 inch heat treated stainless steel ball with a 45,000 GVW rating, 3 inch gooseneck ball (part number FL1005-3) and other special height balls or an inverted 5th wheel kingpin and can be found under Flip-Over Accessories. The gooseneck ball is round and rotates in its socket which keeps the socket clean and can save ball life if you have a coupler that is of poor quality or is rough which a lot of them are. The ball is locked in the one-piece machined steel socket with a stainless steel spring and locking pin. Simply rotate the handle to retract the pin, pull the ball out and store it inverted out of the way in the socket giving full access to your 5th wheel hitch.
The frame is the same for both models: fabricated from ½ inch high grade steel--not A36 structural steel. The frame has two openings to each side and behind the gooseneck ball to connect safety chain hooks to. This frame is rated to 45,000 GVW.
