Built-In Shock Absorption for a Smooth Ride

Executive torsion

If you've ever towed a fifth-wheel trailer before, you're no stranger to road shock. Driving over uneven terrain can result in a rigid, bumpy ride. And uncomfortable fore-and-aft chucking can occur when you're starting and stopping. When all of the motions combine, the road shock can even potentially damage your truck or trailer.

This Gen-Y Hitch torsion pin box is designed to absorb road shock at the connection point to create a safe, smooth ride. This is thanks to the internal construction of the box, which is similar to that of a torsion axle.

Pivot points are built into the Gen-Y pin box. This allows for movement between the box, which attaches to your trailer, and the king pin, which connects to the fifth-wheel hitch in your truck bed. When your trailer bounces or jerks, the king pin will move accordingly.

torsion diagram

Built into the Gen-Y pin box are tubes with inner bars that are surrounded by rubber cords. As the king pin moves, these inner bars twist inside of the tubes, attempting to follow the pin's motion. But the rubber cords prevent the bars from twisting too far. And as each bar turns, these cords compress to absorb the rough shock. This means that any shock experienced by your truck can be absorbed before it reaches your trailer, and the shock experienced by your trailer won't get transferred to your truck.

Video Transcript for Review of Gen-Y Hitch Fifth Wheel King Pin - Upgraded Pin Box - GY45SR

Hello everybody. This is Jeff at Today, we're gonna take a look at this Gen-Y Hitch Shock Absorbing Fifth Wheel Pin Box for your Lippert 1116 and Lippert 1716 pin boxes. And this pin box has a 30,000 pound weight capacity. Now this fifth wheel king pin box is an upgrade to your existing Lippert 1116 or Lippert 1716 pin box that's on your fifth wheel trailer. This pin box will replace the factory pin box on the trailer, and the king pin right down here is where to insert into your truck's fifth wheel hitch.

Now this pin box uses a nice shock absorbing design, which ensures a nice, smooth, steady ride, and the technology in this will function just like a torsion axle, and that limits the transfer of road shock from the trailer to the truck and vice versa. I want to show you the insert of what the insides are made of this right here, where these bolts are. You can see those tubes. We mentioned they have the design of a torsion axle, so they have an outer tube with rubber cords around the inner bar, and those will help reduce chucking and rough four and a half motion and to also limit bounce and jarring up and down motion. What's nice about this pin box is there's no air bag that you have to maintain, and then that you do use fewer moving parts to repair or replace them with some of your other shock absorbing solutions.

This does also offer a unique pin weight scale on one of the lower arms right here, and that scale is built in to help you balance your trailer. The scale will let you know your load needs to be adjusted before you tow, and the vertical load or pin weight on the trailer refers to the weight that a fully loaded trailer is gonna exert downward on your hitch in the truck bed, and too little vertical load can cause trailer sway, too much load could cause poor performance. So I just wanted to zoom in here and show you. Here, you can see the scale right here on this lower arm. So if you look at that scale, it has a red area on top and then a red area right down here on the bottom.

So on top, there's red, on the bottom, there's red. And that's the maximum load at the top, the minimum load at the bottom. And then there's the green area in the middle. So the red areas are too high and too low areas. You do not want to be in that area.

You want to be in the green area. The maximum red up at the top, that scale indicates your maximum vertical load of 4,500 pounds. The very bottom, that red area is gonna tell you there's no vertical load at zero pounds. So you want this white marker over here, this white indicator line, to be in the green area once you're all hooked up and loaded down. That green area will give you your pin weight capacity range of 2,000 to 4,500 pounds. And you do need at least 2,000 pound load, vertical load for this built-in shock absorption system to function effectively. So basically, as we mentioned that line there should be pointing inside that green area. Now this is a nice heavy duty steel construction. Has a real nice powder coat finish on it to resist wear and corrosion. And to install this, it's a very simple bolt-on installation. The mounting holes on this pin box will line up with the factory holes, and they do mount using these included filler shims and the factory or the existing factory bolts. And the reason they include these shims is because of the width on this pin box, on these wings back here, is 12 inches, and to fit it onto the Lippert 1116 and Lippert 1716, they are 12 and a half inches wide, so you need to install the plates, so they'll fit in there correctly. Now these parts are made in the USA, and again, the towing capacity on this is 30,000 pounds. But that should do it for the review on the Gen-Y Hitch Shock Absorbing Fifth Wheel Pin Box for the Lippert 1116 and the Lippert 1716 pin boxes..

This shock-absorbing pin box provides a smooth, safe ride while you tow your fifth-wheel trailer. The all-in-1 box has no air bags to refill or small parts to replace. 4.5K pin weight.


Works very well. There’s a lot less chucking. I don’t regret buying it. I installed myself. I built a wooden pin box, backed my truck under the pin and lowered the trailer to rest on the wooden box. Braced the back end with 2x4’s and removed the bolts. Reinstalled with the same method. The hardest part was lifting pin boxes in and out of the truck.


It is a great great hitch I really like how you don’t feel the axles hitting bumps and railroad tracks. It’s a great design



The Gen-Y gooseneck has been excellent! I now have approximately 12k miles on mine and it rides very nicely with very limited chucking and handles rough roads very well. I’d highly recommend that you contact Gen-Y BEFORE ordering to ensure you get the correct load rating product. Gen-Y and Etrailer have provided excellent customer and tech support! This product definitely frees up your truck bed and does require a precise line up to hitch.


This hitch reduced chucking very well, I have a 2004 3500 Dodge Ram 4x4 Conestoga riding truck with very stiff suspension, the torsion action of the hitch definitely helps when crossing bridges and pot holes. The 5th wheel is an older Keystone Copper Canyon that is in great shape. I Have 12K miles with the new hitch.


I love this hitch I put it on my 35’ Astoria fifth wheel it pulls great and the shock absorbers help with a smooth ride.we took a ten day trip from Ga to Maine last September and had no problems with this hitch. I guess the only negative is that it’s not as easy as a regular fifth wheel hitch to hook up by yourself but after a few times you can line it up ok. The best thing is that no big hitch taking up space in my truck bed just a ball


I have towed now for a few thousand miles since changing to this pin box and honestly wish I had done this years ago! It tows so much better than my 5th wheel box did! Feels more stable, no more bucking and so much softer and better feel when towing! Not to mention so much less hassle dealing with a 5th wheel hitch!


Makes life a lot easier l don’t have to remove my hitch from the bed of my truck to use it. Just flip the ball and there you go.
The gooseneck hitch actually pulls better than the 5th wheel hitch I had.
It is rather heavy so come up with a good plan for installing, I used the front end loader on my tractor which allowed me to do the install by myself.
Great product!!!


Does a fantastic job. After 4 or 500 miles the ride quality smoothed out considerably. Extremely well built!!


I have been well pleased and excepcetionally satisfied with the Gen-Y pin box. We just returned from Texas making a 3000 mile roundtrip and encountered multiple rough roads.There was none of the chucking that I experienced towing with the turning point 5th wheel. A gooseneck is much superior to a 5th wheel in my opinion


I’m really happy with my purchase. Please take into account that this hitch is 2-3” shorter than the kingpin box. They do make an extended version. I had to buy a 4” ball offset, as I couldn’t open my tailgate Without hitting the camper. I love having the open bed space, it seems to be smoother and it’s less noisy then the pin box.


Easy install with a couple people, after install from a fifth wheel hitch it’s noticeable less noisy, less moving parts, frees up bed space and has a much smoother ride. I recommend this hitch 100% for fifth wheel campers.


This product is a chucking ENHANCER, not a chucking dampener. Additionally, despite what you have read, my experience with GenY customer service has been terrible. GenY will not support their warranty program, they will try to tell you everything is OK, when the fact is, their product is faulty and does not function to GenY product literature statements “Built-In Suspension Creates Up to 90% Smoother Ride”.
I purchased the GenY executive hitch from eTrailer on 3/10/23, etrailer sent the wrong unit and to etrailer’s credit - they quickly took responsibility and replaced with the correct unit on 3/24/23. I installed on my DRV Elite Suites PS3 just in time to attend the SOITC rally at the Outer Banks on 4/13/23. When we left for this 750-mile one-way trip, the GenY load indicator was in the middle of the green zone, I measured the pin load at 5,200 pounds. Bedrail clearance was my reason for buying the GenY, it replaced a Trail Air on my DRV and a Reese 27,000-pound hitch on my 2022 F450. Bottom line, the GenY system provided no improvement in bedrail clearance, but did offer the ability to switch in different gooseneck balls to adjust for bedrail clearance.
GenY states that a 1,000-mile break in period is required before the GenY torsion system is fully effective. My experience was that at 750 miles the torsion system on the GenY had sagged to it lowest point with the load indicator in the unit outside of the green, this also resulted in losing nearly two inches of bedrail clearance. It looks like it has a metal-to-metal stop so that the lowest the indicator will go is to the white lines outside of the green. I called GenY from the RV park and was told that the unit would not sag further. I purchased a Curt gooseneck ball which was 2 inches higher than the Ford ball to regain bedrail clearance having to rapid ship it to the RV park.
Chucking became downright scary on the 750-trip home. As an example, chucking was induced every time my truck’s ten-speed transmission shifted up. Upon arrival home, I again contacted GenY customer service with a full expectation that GenY would replace the unit. Instead, here is their response: “I spoke with our QC Manager regarding your hitch. He said that you are in the correct unit and being at the top end of the green is normal after the break-in miles. As for the bedrail clearance he said that you would be able to lower the pin box down a set of bolts (with our pin boxes you are only required a minimum of 4 grade eight bolts per side) or use a B&W ball as they are roughly 1 1/2” taller.” This is unacceptable...


Without a doubt the biggest difference maker I have ever used in my 50 plus years pulling trailers. When my wife had to concede that the Gen-Y gooseneck hitch made such a drastic difference.... enough said!


Great replacement for the Curt Turning Point pin box! Easy to install and took a couple hours since I did it by myself. I had to purchase new 5/8” locknuts as the originals from the Curt install needed replacing. I also had to buy (4) 5/8” nuts from Tractor Supply since the Curt install had nuts welded on the front 4 bolt locations. I used the Curt 5/8” bolts and flat washers since they did not need replacing. I haven’t had a chance to get the trailer on the road yet, but see no reason why it will not pull nicely with the Gen Y gooseneck. It will be pulled with a 2022 Chevrolet Silverado 2500HD 6.6 Duramax and 10 speed Allison transmission.


Shipping on this item was quick and packaged extremely well. The GenY hitch exceeded our expectations. We just completed a 600 mile trip. In the first 100 miles we noticed some stiffness, but after that it loosened up and on the return home we definitely noticed a difference. The hitch is very easy to hook up and as long as you are within a few inches the hitch will center itself and slide onto the ball. We towed with an F350 6 3/4 foot bed and I do not see any need for the 4 inch extension ball setup. A subcompact tractor makes 1 person install of the hitch a complete breeze. The angle is perfect. I ordered the GenY chains and mounting bolts and all worked very well.


The toy hauler pulls so much smoother. I wasn’t expecting to increase my MPG but, I gained a 1/2 mile per gallon. Dealing with etrailer was great as usual.


Best upgrade I have done on my RV. Hitching up a gooseneck is a little more difficult but well worth it. It allowed me to remove the large heavy 5th wheel hitch out of the bed of the truck. I love the damping of the trailer bouncing. This hitch allows my RV move with the truck and I don’t feel that bounce of the truck is passed to the RV hitch like it was with the 5th wheel hitch. Hitch is heave and it really would help to have two people to install it. I’ve done it twice. Once with help and once without. Using the bed of the truck and a lever I was able to install the hitch myself.


Order arrived on time. Packaging looked almost perfect with one corner of the box slightly damaged. Two of us installed the hitch without too much of a problem. It is heavy. Used some WD40 on the inside of the mount. Balance it on the tailgate of the truck. One strong man plus an old guy was able to get it installed. I will update this once we have a couple thousand miles on it.


All I can say is THANK YOU Tiffani S.! At first there was a mix-up and some issues with the order and re-applying a rebate that had expired, but finding Tiffani fixed everything. She was able to make things happen the way they should've from the beginning, and she got me all squared away. I have not installed the hitch yet, but things look like they should fit and are high quality.


Quality build, easy install, let your truck and trailer do the heavy lifting. My wife and I did this install and took about an hour to get it bolted. I also bought the Grade 8 bolt kit. I’m hauling 20K GTW. The original hitch had Grade 5 bolts and only 5 per side. Now I have 6 per side, on bolt torque


This pull so much nocer than a 5th wheel hitch.


This was the perfect replacement for my 5th wheel king pin. It was easy to install and has a much smoother ride! I would definitely purchase this again!


Just wanted to give you a heads up, hitch just arrived as promised. Packing could have been a bit more effective as it is apparent that its been dropped unfortunately it broke the finish in a couple places. I will address it and im not asking for anything as i know your not the shipper. Thanks


Installation was very straight forward, it is heavy so you need something to prop it up for you while you get at least one bolt started in each side. I used the bucket on my tractor to hold it up. I only have one tow in so far for about 50 miles so still early to review. It certainly works as advertised for taking out a lot of the trailer feedback on rough roads, uneven transitions, etc. It is an improvement in ride quality and makes towing a big fifth wheel more comfortable. Necessary? Probably not but it does spoil you a little bit. One problem though that Gen-Y is working on fixing is the ball to pinbox is a little bit longer and I did hit the bed cap at about 60 deg of turn while backing in at an angle. It cleared when I tested it in the flat driveway, but not by much. They are going to come up with a fix. I'm at 7 1/2" clearance from the overhang to the bed caps sitting flat. This is with a '18 Chev Silverado HD 8' bed and a '19 Momentum 351M

  • Correct Gen-Y Pin Box to Replace a MORryde RPB72-1716
    Hey Bill, great question! The Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box - Lippert 1116 and 1716 - 30,000 lbs - 4.5K TW # GY45SR will fit in place of your MORryde RPB72-1716, but you'll want to verify that the 4.5K TW rating is best for your trailering needs. If you look up the GVWR of your trailer and multiply it by 0.22 your tongue weight needs to fall into the 2,600-3,599 lbs range in order for this to work properly. If it's in the 1,600-2,599 lbs range you need the box # GY35FR...
