Arrives before Christmas 
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.
The internal rubber shear spring in this pin box is optimized for trailers that range from 18,001 lbs to 19,000 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.
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 1116 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.

Hi there 5th wheel owners. Today, we're going to be taking a look at Morryde's line of rubber pin boxes. The rubber pin boxes from Morryde offer a much smoother driving experience when hauling your 5th wheel trailer. There are several rubber bushings and shear pins in here that allows movement of our 5th wheel trailer, while keeping our pin box here, where it attaches to the king pin keeps that static down here. And it's able to do this using all the various rubber bumpers inside as well as the shafts here that makes sure that everything is going to stay all together. We're now going to take it out onto our test course.
First, we're going to hit our uneven bump section. That's going to mimic a pothole. Next, we're going to hit our even bump section. That's going to mimic going over a speed bump. And then we're going to see what it's like when we do like a hard turn.
We're going to go ahead and turn around right here. Put it under a nice turn. You can see it still turn just like a normal pin box would.While driving this, the performance benefits seem very similar to an Air Ride pin box. What I've noticed though, is those Air Ride pin boxes you do have to air them up. There is a little bit of maintenance there because the pressure does change as temperatures change, so you do have to just keep an eye on those, whereas something like this is a completely maintenance free option due to the rubber pads.
The pads are replaceable so if over time, maybe many years of service, they start to wear down a little bit, you can replace them.Up at front, we have a crushed bumper here. There's also one just like this located in the back. And this is really for when you're stopping and starting, and only if it's an extreme movement because it will slide on these shafts. The trailer will slide forward and as it does, this bumper here, will contact on the surface up here if you do have enough forward motion. So I guess maybe an emergency stop, you slam on the brakes and the trailer goes up, this bumper is going to adhere.
All these components are going to absorb that impact, so you're not going to feel it nearly as much as you would if you just had a solid pin hooked up to your truck. It would just be, boom. It would be very abrupt. Something like this is going to help absorb that impact, but we do also have our shear spring down inside here that allows for movement as well. That sheer spring is kind of the most magic part of the assembly. That's what determines the amount of weight that the pin box is rated for.Our glide pads here are a self-lubricating material and these allow it to slide easily on the surface. You can almost see it kind of here. This one's been out in service for a while and you can kind of see how it's nice and shiny in this location here where the puck does glide on it. So it helps support that weight up, so the sheer spring can its job properly dampening the movement because the main purpose of getting a rubber pin box like this is to smooth out your ride to help reduce chucking and jerking whenever you take off and whenever you stop. It really does help to absorb a lot of that.The movement that we do have available here, we'll have about three inches of forward and backward movement and about an inch and a half of side to side movement. Not so much side to side. It's mainly that forward and backward because it's mostly starting, stopping. That is where there's really going to make a huge difference in the feel of your trailer. You're not going to feel like every time you take off, like you're lugging this big load. It kind of eases it in, so you can just take off and it feels much smoother and then when you come to a stop, it's not like you have all this weight just barreling and pushing on you. It kind of absorbs a lot of that and it's just a much smoother operation that just overall, it's going to give you more control over your trailer because you're just going to feel like you have more control. You're not going to be as tired and gripping the wheel as much. Just really overall is just going to smooth things out and give you a little more energy when you get to your destination and overall, be more comfortable for all of your passengers.There's a few things to keep in mind when determining the pin box for your trailer. There are various different ratings for the Morryde pin boxes and also the fits. You'll want to know the make of your trailer. You'll want to know the trailer's weight rating, not the pin box's rating that you currently have. You don't want to use that. You want to know how heavy your trailer is. And you'll be using those to help determine which replacement Morryde is going to be for your trailer. And that completes our look at Morryde's line of rubber pin boxes.

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.Always a great experience ordering from etrailer
Installation instructions were very good! It fits perfectly.
Beware when ordering a part this heavy, the shipper only delivers to the curb.
I ordered this for my Grand Design 337 5th wheel to help reduce the chucking. I will start this with the order. The Pin Box arrived in a very beat up box. After examining the unit I found that one of the bolt fins was bent about 1" inward, the carrier must have dropped this from a truck. I called E-Trailer support and spoke with a very nice gentleman who took my info and said this does happen occasionally. He set up an advance replacement and prepaid return which shipped 2 days later. The new one arrived in good shape.
I installed the unit today. I am extremely surprised how easy it went replacing the King Pin box. The MORryde box is heavy, using the bed of the truck and some 6x6's I got it the right height and really easy. I found cleaning the bit of rust the housing that the MORryde sits in and a little WD40 made this easier.
I have not connected to the hitch and pulled the camper yet but have heard great things about this unit. I have the PullRite Auto Slide hitch so I had to install the adaptor as well.
Many thinks to Etrailer for taking care the shipping issue and getting me a working unit, well done.
Entirely better experience towing, my wife and I picked up our 1st 5th wheel toyhauler camper and towing it home it started jerking back n fourth, not knowing what the hell was going on she wanted to return it. I did some research and found this Moryde cushioned pin box and it’s super smooth. We’re both very happy and feel a lot more comfortable towing places.
Ordered the Morryde pin box to replace the Rhino pin box on a 2022 Riverstone Reserve. Shipping from Etrailer was right away but had a little delay with the shipment because the semi truck could not get up my road. Taking off the Rhino pin had a little trouble as one of the bolts was cross threaded, which I have read from others also having the same issue. The Morryde came with all the hardware and with two people had it changed out in about an hour. Took it for a small drive and really seems to make a big difference, will get it out for a longer drive soon on my next trip. The new pin box went in the same position as the old one and did not change my level or bed clearance.
This kingpin box was promptly delivered after ordering. We installed the new Moryde today and it went on very easily. Although it is very heaving, I used my tractor with a front end loader to remove the old pin box and install the new which really made it very easy. I hooked up to my truck to test the level and everything was perfect. Very satisfied! Thank you etrailer.
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.
MORryde makes a fantastic Pinbox! I have been a e-trailer customer many times over and always find the customer care from start to finish is great. We recently purchased a 2024 Brinkley Z3100 which came with a Rhino Pinbox.
I hated it! Lots of chucking. Our other 5th wheel a King of the Road has the MORryde on it and pulls like a dream. I had asked the dealer at time we made our new purchase about putting on the MORryde on it and I was told it could not be done.
Don’t ever take just one persons word as gospel and further looking into it, there is definitely a conversion available and thanks to the folks on my Brinkley Owners page and the folks at e-trailer, I ordered it and it is a perfect fit. Definitely takes 2 guys to put it on but I’d say its a 2-3 hour job.
Our install took us about 5 hours as one of the original bolts with the Rhino was cross threaded. Can’t wait to get out and tow with our new MORryde!! They are the best!! Thanks e-trailer for your help!
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.
It was a nice upgrade over the solid pin box my fifth wheel had. The MORryde pin box did improve the quality of the the ride in my tow vehicle. I would recommend it as a good value for the money.
Good price and quick free delivery.
The product is so much better than the stock pin box.
Very easy install and very happy.
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.
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.
This MORryde pin box eliminated our chucking, which is precisely why I bought it. It also smooths out passing over bridge joints, potholes, etc. Definitely recommend.
I received my order in a timely manner. Three or four days after submitting it. It was delivered by truck in a sturdy box strapped on a pallet. No damage to the box or contents. Installation was a breeze. Fitmant was perfect. Upon test driving after installation I was happy with the performance of the rubber pin box. Works as advertised.
Product was received as expected. Installation went very well. I am eager to try it out this week on the road!
just had it installed works great and looks good
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 !!
Probably the single best addition to my fifth wheel. We have a grand design solitude 2930. Connecting to the trailer is so much softer and taking off from stops is smoother. The chucking is all be gone. I’d highly recommend this as one of the first upgrades
Not a very good ride, a lot of chucking sensation.. Should have kept my Rhino pin box.
