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 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 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 5thwheel 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.
The 205ST30K unit comes with a standard gooseneck ball 30,000 GVW, which is suitable for any standard gooseneck trailer. This also works on Cab and Chassis except for some Dodge models and for the Dodge and some Fords, use the -T models so they clear your exhaust.
The 205ST45K comes with a 2-5/16 inch heat treated stainless steel gooseneck ball and a 45,000 GVW rating. This also works on Cab and Chassis except for some Dodge models.
The 205ST30K-T, 30,000 GVW gooseneck hitch is a special that sets 2 inches taller for some Dodge and Ford Cab & Chassis that is needed to clear the exhaust.
The 205ST45K-T, 45,000 GVW gooseneck hitch is a special that sets 2 inches taller for some Dodge & Ford Cab & Chassis.
The hitch installs behind the 5th wheel hitch on your semi-tractor and sets over the frame. It requires 10” lateral on the top of your frame and 4 inches down the side. It has three ¾” holes on each side to attach to your tractor frame and six ¾ inch grade 5 bolts are included.
