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 is optimized for trailers that range from 18,001 lbs to 21,000 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 18,000 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 Rhino 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.


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 to your customer support staff and picking out the right pin box, I ordered it the next day on line. Shipping was fast and it arrived in good shape. The Pin box came with all the bolts and Hardware, it took about an hour to install on my 2024 Momentum M class RV. I took it for a 2-hour road trip and you cannot believe the difference in the ride. I am never disappointed when I deal with etrailer.



by:

All was good except it was short on hardware. 8 bolts, 10 washer 5 nuts, 6 lock washers. I needed 10 of everything. Rino box's have 6 bolt that go into welded nuts and only 4 bolts with nuts. Even using those I'm still two short. 50 miles to a hardware store in search of 3/4 nuts.
Sad day.

A sad day indeed. Missing hardware is never fun. I will have our Customer Service team reach out to you as quickly as possible.

just had it installed works great and looks good



by:

The pin box was delivered on time, it’s a pin box, and I have not installed it yet. But it’s performance, or quality, or lack of either, would be a reflection on MoRyde not etrailer. Delivery was on time and the etrailer staff had answered my questions prior to ordering in a prompt manner.

So far this is a welcome upgrade. Took it on a short trip over some rough road that normally triggers chucking on my F-250. This pinbox prevented it which was a welcome change. I’m looking forward to some longer trips.

Installation was straightforward. Removed the old pinbox which was fairly easy. Installing the new pinbox would’ve been a challenge had my buddy not had a forklift attachment for his tractor. I don’t know the exact difference in weight between the old Lippert pinbox and the new Moryde, but it is substantially heavier. I’d say 2 people muscling and one to install the hardware would still be a challenge. Forklift or similar is the way to go. Also, the new pinbox doesn’t come with new hardware. Got to use your old or make a trip to Lowe’s/Home Depot.

All and all I’m happy with the upgrade, but I thought it was pricey and don’t like the additional weight.



by:

I have not installed this part on my 2021 momentum 395MSR yet, but it was received in perfect condition. I had the same pin box on my Solitude390RKR and loved the way it handled. If the part does not perform as expected once installed and after I have some miles behind it i'll update my review.



by:

This cushioned pin box is definitely worth the upgrade. Chucking is greatly reduced (There's no getting totally away from it) and the frequency of the chucking is tempered making the ride much more pleasant. There are times when you forget your towing it's so smooth on decent stretches of road. Delivery was quick (3 days early as a matter of fact) and driver dropped it in my garage. Plus the fitment was perfect, bolted on with no problem. Entire experience was good !!



by:

Installed this MORryde cushioned pin box on a 20K# toyhauler(from a solid pin). Comparing 9K miles before and 11K miles after, it made a remarkable improvement in the ride, especially on choppy, rough roads (think I-40 across New Mexico). Easy bolt-on installation. I consulted with the staff @ etrailer.com to ensure the correct hitch model was selected. Shipping was straight forward via truck freight. Excellent communication through the process.



by:

Product was received as expected. Installation went very well. I am eager to try it out this week on the road!



by:

Trailer tows so much better with the new pin box.



by:

While not yet installed thought it worth commenting on the experience thus far - in a word “excellent”. Package was well packaged, the transporter was awesome and kept us informed of his delivery schedule, given the weight of the shipment.
Bottom line, the process to date has been outstanding and would highly recommend using etrailer for your rv needs.



by:

Fit perfect on my Grand Design Reflection 303RLS. Will be taking a long trip very soon and will let you know how it performs.



by:

The king pin box was delivered in perfect shape. Metal banded, strapped to a wood pallet in a card board box. Upon installation it fit perfect.
The customer support was excellent throughout the whole process from the ordering, making sure the correct king pin box was selected, to follow up, due to the long wait. The long wait was due to Covid 19. I am a happy camper and cannot wait to try it out on the road soon. I will send a follow up review. Thanks etrailer and especially Christina J. she answered all my questions and followed up on time every time.



by:

The hitch is great. The fact that etrailer only offered one shipping method was disappointing. Upon placing the order, requested a faster more reliable shipping method. This was not an option. The item arrived the Thursday after the estimated Monday delivery. Tracking proved that the item sat in warehouse depots for 11 of the 14 shipping days. This was very frustrating.



by:

It took me about an hour to remove the old one and install the Morryde! Out local camper dealer wanted $700 to do that! I guess I'm worth more than I thought!



by:

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.

  • Length Of The Curt Flex Air 5th Wheel Pin Box # LC369535
    The distance from center of king pin to front row of bolt holes on the Curt Flex Air 5th Wheel Pin Box # LC369535 is 20-3/4". This would be a bit longer than the MORryde Cushioned 5th Wheel Pin Box for 18K to 21K Trailers w/ Lippert Rhino # MR55QR you were looking at and also has a different bolt pattern (1621), so you'll want to confirm the bolt pattern of your current pin box prior to purchasing a replacement.
