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 18,000 lbs, the internal rubber shear spring is optimized for trailers that are under 11,500 lbs. A rubber spring built for 18,000-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 18,000-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 Lippert 1621HD 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.

Ratings & Reviews
The Moryde pin box exceeded my expectations on eliminating chucking over the factory Rotaflex pin box. When Braking or accelerating our 16,000 lb Montana all the banging noise from the pin box is gone, making an Improved ride in the cab. Note it does seem to benefit from the larger low friction lube plate verses the smaller friction plate the Rotaflex pin box utilized.
So far very nice. I was able to install it myself using my pickup bed,a small hydraulic car jack, and a big I made. The whole process of removing old and installing new took about 45 minutes. Everything lined up beautifully. Hooking up to receiver was standard. Took a 10 mile test run. Not disappointed.
This is the first thing I would ever buy For any fifth wheel that I have. There is a big difference with this system. It saves on your truck, fifth wheel and your passengers when traveling down the road. I have installed it and the spring of 2026. You can install it by yourself as long as you’re a little mechanically inclined and can squat a little bit of weight. Have hauled the fifth wheeler to three different camping locations and have not had an issue. It takes away all the clunking and vibration. Looking forward to hauling it to Yellowstone. I highly recommend this!
I replaced my rhino pinbox on my 5th wheel with the morryde pinbox. I had this on my other trailer and it worked great. This setup works just as good as before.
Quality products, no problem swapping out OEM Lippert Rhino Box for MORryde cushioned hitch. Even upgraded "pin plate" in order to attach Andersen hitch. Not towing camper until 1 August, so I can not comment on hitch capability. Before upgrade, towed camper about 30 miles from dealer to campsite w/ original Andersen set up, a little to much "hitching" and bumping. That's why I upgraded to the Morryde cushioned hitch. Still trying to figure out optimal location to install hitch ball connect/disconnect handle.
This pin box arrived on time and the box was in very good condition. The freight company used their lift gate to put the pallet into the bed of my pickup. That made it possible for this 63 year old to uninstall the old and install the new single handedly.
My main complaint with the old pin box was chucking. I’ve now towed more than a thousand miles with the Morryde. While the chucking has improved it has not been eliminated. I would say it has been reduced about 50%. Bridge abutments are less harsh. Concrete roadway gallop much improved. A significant improvement but not what I had hoped for based on other reviews.
I installed this today on my Grand Design Reflection 303. Talking with rep they recommend the 1621HD. I kinda think I should have gotten the lighter unit. My 303 GVWR is 11995 lbs. the HD is good heavier units.
I still helps, I towed it today and I noticed some improvement. I would consider getting the lighter unit if I had it to do again.
I have had this pin box before on other campers and loved it so when we got our new camper this was the first upgrade that I wanted.
A tip to an easy install, lock it in your hitch first then back it right into your camper. I shored up the head with a 2x4.
King pin does what it suppose to, less jarring on rough roads and when stopping and starting.
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.
Just what I needed for my fifth wheel, haven’t pulled it yet. My friends all have them and say it takes the jerk out. Wife has neck problems, so I’m sure it will help.Shipping was quick and packaging was excellent.

We installed this pinbox on our 10,000 lb 5th wheel camper and paired it with a B&W Champion hitch on our 2024 F350 long bed pickup.
The cushioned pinbox has performed well both in stop & go traffic in new england and on the gargantuian frost heave sections of the Alcan highway. Going on 10,000 miles so far...and have no issues.
Very great product, took the chucking and jerking out when towing my fifth wheel, would recommend it to anyone, wish I would have gotten it years ago.
Very satisfied with the purchase. E-trailer is great to do business with and the product was great. Easy to install with 2 people but I got it done by myself with the use of my tractor to hold in place while mounting. Improved the ride while pulling trailer. Just what I was hoping for. Pin box is very good quality. No regrets.
Quality heavy built pin box, only complaint was a couple of 1/4" square spots where the powder coat didn't stick near the pin end, nothing that a little touch up paint won't fix. Well packaged, and promptly delivered. Still give 5 stars.
Dramatically reduced chucking as hoped. There is more start/stop slop than I had expected but I'm guessing that is due to my trailer being at the top of the weight rating for the rubber block. I need to put a camera on it to verify my theory. All in all a huge improvement.

Still working great. The aforementioned slop really isn’t much of anything. Works like a dream.
We recently purchased a new camper from an individual who had added a gooseneck adapter. We purchased the MORryde cushioned pin box and took it with us when we picked up the camper - we changed it out in the driveway in about one hour. The ride home was very smooth. We have some rough bridge transitions in our area and the MORryde handled them with ease.

Glad to hear it was a quick and easy swap Brent! Where did you take your new 5th wheel for your first big trip?
Do you have a question about this 5th Wheel Pin Box?
