Fifth Wheel Pin Boxes

How Do 5th Wheel Pin Boxes Work?

Towing a fifth-wheel RV is very different from towing a travel trailer. As an alternative to being pulled along from the bumper of your truck, you tow a 5th wheel from the bed. Before we can understand what a pin box is, let's look at what a pin box is. This box is a box made of engineered steel that is attached to the front of the trailer frame. The pin box contains the coupling system for attaching the trailer to the tow vehicle.  

How do you measure the 5th wheel pin box?

You can use the drawing to measure the horizontal and vertical bolt hole distances, bolt size and bolt head size, front row of bolts to kingpin, and back row of bolts to kingpin, as well as the pin box width. In addition, record how many bolts are used to secure the pin box to the frame of the trailer.

What is the pin box on a 5th wheel?

Located on the front of the trailer frame, the pin box is an engineered steel box. It is this pin box that contains the coupling system that connects the trailer to the tow vehicle. Using the kingpin, the trailer is connected to the 5th wheel hitch by sliding into the U-shaped receiver on the hitch.

A 5th wheel pin box can be of several types, each with its own design, suspension, and coupler. Solid units are more affordable and do the job. There are other methods, such as rubber cushions or airbags, that provide cushioning. As a result, the latter will provide a better ride and feel for the tow unit. Despite the fact that you might not realize it, your fifth-wheel towing experience depends heavily on the pin box, also called the kingpin box.

When it comes to comfort and turning clearance, it can impact the ride if you don't have a cushioned pin box, and it can also affect how comfortable the ride is if you don't have one. Like everything else, your pin box will eventually need to be replaced for a variety of reasons.

Several factors might lead you to need to replace your pin box. It's possible that your fifth wheel's pin box was damaged and needs to be replaced so you can safely tow it. If your current pin box is technically fine but has no cushion or shock absorption, you are likely to have an uncomfortable ride. Maybe your truck bed is shorter than 8 ft, and you're tired of constantly having to slide back your fifth-wheel hitch every time you make a sharp turn, so you'd like to install a Sidewinder pin box.

Don't worry if you relate to any of these scenarios. During the replacement process, we will provide you with all the information you need to make your pin box last as long as possible.

Different shapes and sizes of pin boxes are available. You can get a Sidewinder pin box if you don't have a sliding fifth-wheel hitch on your short bed. Pin boxes with Sidewinder pin boxes have a rotating turret that automatically moves back when turning to give your truck more turning clearance. You can stay in your truck with no worries instead of having a sliding fifth-wheel hitch that requires you to get out every time you turn 90 degrees.

The pin box can be cushioned and equipped with shock absorbers for a more comfortable ride. Pin boxes of this type will reduce the jerking and chucking you'll usually feel when towing, so much so that you won't even notice your fifth wheel is behind you!

King Pin Boxes: How to Replace Them

As a custom-fit item, pin boxes can be selected based on the make, model, and year of your trailer, but there is no way to determine which one to choose based on the hitch's year, make, and model.

Finding the pin box's manufacturer name along with its specific pin box number is the easiest way to replace your pin box. Both of these can usually be found on a sticker on the pin box or the kingpin itself. A pin box number is usually three or four numbers long and can have letters attached to it. One of Lippert's most common pin box numbers is 1621. Another is 1716, and another is 1116.

It is possible that over time this number disappears (strange how that happens, right? ), so you may not be able to find it anymore. The trailer manufacturer may be able to cross-reference your pin box number with the VIN number of your fifth wheel if they are still in business. Otherwise, there's still another way to find out what your pin box number is so you can replace it.
