Upgrade the factory pin box on your fifth-wheel trailer to this cushioned model that dampens road shock and reduces back-and-forth chucking for a more relaxed towing experience. Unlike air bags, the internal rubber spring requires no maintenance.
Features:
Specs:
Most standard pin boxes are constructed of steel and are built with the sole purpose of connecting your fifth-wheel trailer to your tow vehicle. There is no cushioning built in, so a factory pin box doesn't do anything to provide a comfortable ride when you're hauling your fifth-wheel trailer.
This MORryde pin box, however, is built with an internal rubber spring that absorbs road shock and vibration at the connection point. So if you're driving on unpaved roads or uneven pavement, this pin box will prevent any road shock and vibration you encounter from transferring from your tow vehicle to your fifth-wheel trailer and vice versa. In other words, the rubber spring takes the brunt of the impact so you and your towing setup don't have to. And because this unit uses a rubber spring instead of an internal air bag like some other upgraded pin boxes, there's no maintenance required.
Although this pin box can tow up to 19,000 lbs, the internal rubber shear spring is optimized for trailers that range from 14,001 to 18,000 lbs. A rubber spring built for 19,000-lb trailers would be too stiff to provide any cushion for an 14,000-lb trailer, while a rubber spring built for 14,000-lb trailers would be too flexible for a 19,000-lb trailer. To get the best results from this cushioned pin box, the sweet spot is a trailer in the 14,001-lb to 18,000-lb range.
Chucking, the back-and-forth jerking movement you feel in your cab when towing, occurs most frequently during starts and stops and while making turns. A typical, factory pin box creates a rigid connection without much give. So when a harsh stop occurs, all of the trailer's forward momentum gets forced through that stiff connection, slamming the king pin in the hitch and jerking your truck around.
To combat this, glide pads are built into the MORryde pin box that allow the skid plate to shift up to 3" forward and backward and 1-1/2" side to side to compensate for some of that violent motion so that you don't have to feel it in your cab.
This MORryde pin box is a direct replacement for your existing Dexter 221002300 or Leland 7920/7921 pin box, so the installation is very straightforward. After removing your old pin box, the MORryde can be mounted into place using the same hardware and bolt holes used by the factory pin box.
Because of the weight of the unit, you'll want a couple of friends to help you lift it into place during installation. Once the hardware is securely bolted down, you'll be ready to go.

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this MORryde Cushioned 5th Wheel Pin Box for the Dexter 221-0023-00 pin box. And also, the Leland 7920 and 7921 pin boxes. Now this is built for trailers that have a gross vehicle weight rating of 14,000 to 18,000 pounds. And this is a cushioned pin box which will replace your current one for a lot smoother towing experience. This will let you enjoy a nice chuck-free, jerk-free ride thanks to the rubber shear spring that's on the inside.
And that rubber shear spring will reduce any back-and-forth chucking. It absorbs a jarring movement at the connection point and it will dampen up to 1 1/2 inches of side to side movement and three inches of front to back movement. I do want to zoom in just to show the area where that rubber spring is. We can't really see it cause it's basically inside here above the kingpin, but that rubber shear spring will help dampen the transmission of forces from the fifth wheel to your vehicle. Makes your starts and stops jerk-free.
And what's nice is it requires less maintenance than the air-filled spring model pin boxes. This will also give you the same king pin location as the original manufacturer to help reduce stress on the trailer frame. Now to install this, it is a fast, very easy bolt-on installation. All you want to do is make sure when you remove your factory pin box, make note of the bolt hole locations cause you want to mount this pin box in the same hole settings using the existing factory hardware. This pin box exceeds CSA standards.
It is made in the USA. Few specs on this, again, the application fits fifth wheel trailers with a 14,000 to 18,000 pound gross vehicle weight rating. Total weight capacity for this pin box is 19,000 pounds. But you do want to remember that the pin box capacity will not change the overall gross vehicle weight rating of your trailer. And the last thing I want to do is give you just a couple about three different measurements on this.
The overall width on this, back here where you mount it from outside the outside, about 14 inches. And then the last two measurements are going to be from the center of the King pin up here to the center of the front row of mounting holes from the center of the King pin to the back row of mounting hole. And I made a mark up here to make it easier to measure for you. If we put our ruler on the center to the center of the front row, is right at 18 7/16 inches to the back row is 25 7/16 inches. But that should do it for the review on this MORryde Cushioned 5th Wheel Pin Box for the Dexter 221-0023-00 pin box and the Leland 7920/7921 pin boxes..
