Rubber Shear Spring Absorbs and Dampens Road Shock

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.


The internal rubber shear spring in this pin box is optimized for trailers that range from 14,001 to 18,000 lbs to ensure that it provides just the right amount of shock absorption for your application. If this pin box were to be used on a larger trailer, the spring would be too stiff to provide enough cushion. And if your trailer's GVWR was less than 14,000 lbs, then the spring would be too flexible to provide adequate support.


Less Chucking for a Better Ride

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.


Bolt-On Installation

How To Install MORryde Pin Box

This MORryde pin box is a direct replacement for your existing Lippert 1621HD pin box, so the installation is very straightforward. After removing your old Lippert pin box, the MORryde can be mounted into place using the same hardware and bolt holes used by the factory pin box.


MORryde Pin Box Bolt-On Installation

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.

After talking with a couple of the sales raps, we were able to obtain the right product. It was shipped it was delivered on time. We picked it up at will call installed it a few hours later with no trouble at all. We would recommend etrailers and this product to anyone.



by:

This is an excellent pinbox and hopefully I’m saving some wear and tear on my trailer. We have a Superglide auto slide hitch and the Morryde adapter sure beats the capture plate I had before. No more chancing a broken foot when it accidentally falls off.



by:

Towing our 36' toy hauler with this pin box is much less jarring than the original pin box. It definitely isolated the movement of the trailer from the truck.



by:

Love the new pin box. It has performed as advertised and provides a much smoother ride!



by:

This hitch is awesome. It works much better than expected and makes towing our 5th wheel a very pleasant experience.



by:

So far 5 stars. I have not towed with it yet. Install took about 2 hrs and not to bad. Pin box weighs probably double the LCI. Very sturdy and is expected really help the towing experience.



by:

Great product is everything l expected can't wait to install it and try it out. Received it in a very short time. Very happy with Etrailer will buy more products with them.
