Frequently Asked Questions
What is the primary function of the KP2BP adapter?
This adapter allows a trailer with a gooseneck coupler to be towed by a truck equipped with a 5th wheel hitch. It essentially converts your 5th wheel plate into a 2-5/16″ gooseneck ball by locking the kingpin directly into the hitch.
What is the weight rating for this adapter?
The KP2BP is built for heavy-duty performance, featuring a solid 2″ kingpin and a 1/2″ thick bolster plate. Both the ball and kingpin are rated for 30,000 lbs.
Can this be used on a semi-truck or tractor-trailer?
Yes. The KP2BP is compatible with standard semi/tractor-trailer 5th wheel hitches, making it a versatile tool for moving gooseneck trailers with larger rigs.
Why is it necessary to “block” the 5th wheel plate?
You must block your 5th wheel plate to prevent it from tilting or articulating. If the head is allowed to move, it creates excessive leverage and stress that can damage the adapter or lead to equipment failure.
Is the KP2BP recommended for daily highway use?
No. This adapter is intended for short tows and temporary transport, not as a permanent, everyday towing solution. For regular highway use or long-distance hauling, we recommend our dedicated Gooseneck Kingpins.
Will I need to adjust my trailer height?
Because the 5th wheel hitch height may differ from a standard gooseneck ball height, you may need to adjust the main coupler tube on your trailer to ensure it rides level during transport.
Where is this product manufactured?
Like our other premier towing products, the KP2BP is proudly made in the USA to ensure the highest quality and safety standards.
How large is the mounting surface of the adapter?
The adapter features a 10″ diameter bolster plate that is 1/2″ thick, providing a wide, stable base for the 2-5/16″ ball to sit against the 5th wheel plate.
Who can I contact if I’m unsure about the fit for my application?

What our customers are saying
“This is a 2019 Ford F-150 with 5’5” bed. I was worried about finding a product to get the clearance I needed to pull my horse trailer . My trailer is almost 79 inches wide . Installed the SB116 16” inch extension coupler on my trailer and I’ve pulled it several trips now and it works great. My trailer pulls great due to load is on the truck where it needs to be. Very well made and love the fact I don’t have to get up in the back of truck or reach over the bedside to hook up and unhook. The folks at PopUp Towing were great to deal with and answered all my questions.”
- Mark G.
“We installed a CAG (Connect-Adapt-Go) from PopUp Towing on a truck recently. It went in very easily. Instructions were very clear and we are very pleased in the outcome. We will definitely do more business with PopUp Towing.”
- Rick & Jean Horsch
“We purchased a CC2 Cushion Coupler by PopUp Towing. I’ll tell you what, after arriving home from the last horse show, we were amazed to find two cans of pop that were left on the dinette table still on the table. Now that’s a smooth ride!”
- Larry P.
“I was having trouble explaining my issue and determining a solution to my turning issue when towing my gooseneck trailer. A friend of mine said, you should try to call the guys at PopUp Towing as they helped solve his issues. Let me tell you, I spoke with two gentlemen at PopUp if I remember correctly their names were Derrick and Chance, those to guys seem to have more knowledgeable information than anyone I’ve spoken with in this industry. Years of valuable knowledge, and highly recommended if you have similar issues. Thanks again and I absolutely love the new RVGC complete pinbox replacement to allow me to tow my 5th wheel without the bulky 5th wheel hitch taking up my bed space.”
