Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Mainly have issues with chucking (when your trailer pushes or pulls your truck) and want to smooth it out
  • Hate having to do maintenance - no need to find an air tank or make any adjustments before taking off

No, if you:

  • Frequently drive over really rough, washed-out backroads or poorly maintained highways and need something to give you more cushion
  • Feel like your trailer is bouncing up and down - this pin box doesn't help a whole lot with vertical movement
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. 1-636-306-4830 to order MORryde fifth wheel king pin part number MR74VR or order online at etrailer.com.

  • Bolt-on installation no drilling required
    • King pin sits in same location as factory king pin
  • Made in the USA

    • Designed to replace Lippert 1621HD pin box
  • Pin box weight capacity: 18,000 lbs
    • Do not exceed the GVWR that is listed in your trailer's manual
  • Spring capacity (for optimal ride): 11,501 lbs - 14,000 lbs

  • 3-Year limited warranty (or 70,000 miles)


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.


Although this pin box can tow up to 18,000 lbs, the internal rubber shear spring is optimized for trailers that range from 11,501 to 14,000 lbs. A rubber spring built for 18,000-lb trailers would be too stiff to provide any cushion for an 11,500-lb trailer, while a rubber spring built for 11,500-lb trailers would be too flexible for a 18,000-lb trailer. To get the best results from this cushioned pin box, the sweet spot is a trailer in the 11,501-lb to 14,000-lb range.


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.

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.

I ready like the ride it has produced. I was skeptic about much it could improve the ride, but Both my wife and I were extremely surprised on how it changed the ride. I'm glad I took the plunge to purchase this pin box. This will allow for longer rode trips in the future.

Review from a similar Cushioned 5th Wheel Pin in Fifth Wheel King Pin


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.

Review from a similar Cushioned 5th Wheel Pin in Fifth Wheel King Pin


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.

Review from a similar Cushioned 5th Wheel Pin in Fifth Wheel King Pin


wow what a difference this pinbox made 99% of the chucking is gone, the ride is so much smoother and enjoyable. I highly recommend this pinbox for anyone pulling a 5th wheel. Etrailer had it in stock and shipped promptly. I do reccomend 2 people as it is heavy.
Very simple install.

Review from a similar Cushioned 5th Wheel Pin in Fifth Wheel King Pin


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.

Big difference from the rhino box, no more chucking makes better towing. Peace of mind

Review from a similar Cushioned 5th Wheel Pin in Fifth Wheel King Pin


Bolted Right up. Sure does take out the chucking to only a little bump here and there. Without this device, my coffee cup would hop out of the holder.

I bought and had one for my previous camper as well. I won't be without.
