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 are under 11,500 lbs. A rubber spring built for 19,000-lb trailers would be too stiff to provide any cushion for a trailer under 11,500 lbs, while a rubber spring built for trailers under 11,500 lbs would be too flexible for a 19,000-lb trailer.
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 more ride cushion, fifth wheel pin box for the Dexter two two one dash zero zero two three dash zero zero pin box. And also the Leland's 79 20 and 79 21 pin boxes. Now this is built for trailers with the gross vehicle weight rating of up to 11,500 pounds. And what's nice is this is a cushion pin box and a replace your current one for a lot smoother towing experience.
This'll let you enjoy a nice chuck free jerk free ride. Thanks to the rubber shear spring that's mounted on the inside. That rubber shear spring will reduce your back and forth chucking. It absorbs any jarring movement at your connection point. And it'll dampen up to one and a half inches side to side movement and up to three inches front to back movement.
When the zoom in, just show you where it's located you can't really see the rubber shear spring, cause it's up underneath right above the king pin underneath here but that rubber, sheer spring dampen the transmission of forces from your fifth wheel to your vehicle. So it makes your starts and stops jerk free. And of course it will require less maintenance than those air filled, spring model pin boxes. Also what's nice is this will give you the same king pin location as your original manufacturer to reduce the stress on your trailer frame. Now to install this, it is a nice, fast, easy bolt on installation.
Your bolt holes right back here. Now you do want to make sure you make a note. When you remove your factory pin box, you want to make a note of the bolt hole locations of your factory pin box because you want to mount this pin box in the same hole settings using your existing factory hardware. This pin box will exceed CSA standards it's made in the USA. Again, the application, it is fits the fifth wheel trailers with up to 11,500 pound gross vehicle weight rating.
Now the total weight capacity on this pin box is 19,000 pounds. You just want to remember that this pin box capacity will not change the overall gross vehicle weight rating of your trailer. Last thing I want to give you is a few measurements. First one, I want to give you the overall width which at the back here from the outside to the outside if we put a tape measure on it, it's right at 14 inches. And then the two other measurements are going to be from the center of your king pin, right up here to the front row of mounting holes and from the center of the king pin to the back row of mounting holes. I have put a mark right up here to make it easier where the center of the kingpin is. So if we go from there, to the front row of holes is going to be 18 and seven 16ths inches. And so the back row of holes is 25 and seven 16ths inches. But that should do it for the review on the more ride cushion fifth wheel pin box for the Dexter two two one dash zero zero two three dash zero zero pin box and the Leland 79 20 and 79 21 pin boxes..
