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.
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.

Hi everybody, Andy here with etrailer.com. Let's take a look together at this Gen-Y Hitch shock absorbing fifth wheel pin box. Now, this is going to upgrade your existing pin box on your fifth wheel trailer. The king pin is still gonna insert into your truck's fifth wheel hitch. And this does have a shock absorbing design that's going to give you a smooth and steady ride. So it's gonna be a lot more comfortable for you as you're going down the road.
Now, this is designed specifically to replace the Fabex 665 and M&M 665 fifth wheel pin box. So if you have either one of those, this is going to fit right in place. And the installation is going to be relatively simple. This has the same mounting holes and this will install with the included 5/8 of an inch diameter bolt and hardware. So that is included with this pin box.
Now, the installation is going to be pretty simple. However, it might be not as easy just because of the weight of this pin box. So this pin box is very heavy. I needed help to put it on the table here before our time together. So you do wanna make sure that you have plenty of support as you lower your original pin box and put this one up in its place.
Just make sure that you have plenty of support when you're installing this and you'll be good to go. I do wanna point out that this pin box is a little bit shorter than your original Fabex or M&M 665 pin box. The clearance between your trailer and your tow vehicle during turns might be reduced. Now, this is made here in the USA of a heavy duty steel construction. And the towing capacity is 21,000 pounds and the pin weight range capacity is from 1,500 pounds to 3,500 pounds.
Now, the pin weight capacity range is due to Gen-Y's shock absorbing design, which is gonna give you that smooth and steady ride. Their technology functions like a torsion axle to limit transfer of road shock from trailer to truck and vice versa, reducing chucking and the rough for and apt motion. It also limits bounce and jarring up and down motion. Now, as this cutaway demonstrates here, built into Gen Y's pin box are tubes with inner bars that are surrounded by rubber cords. And as the kingpin end moves, these inner bars are going to twist inside of the tubes attempting to follow the kingpin's motion. But these rubber cords are gonna prevent the bars from twisting too far. So as each bar turns, these cords are gonna compress to absorb the rough shock. So 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. So because of that shock absorbing design, you are going to have to have a minimum of that 1,500 pounds for the system to operate properly, for it to properly engage, but then any more than the 3,500 pounds is gonna be too much for it. Another benefit of having this type of system is that there's no airbags to maintain, there's fewer moving parts to repair or replace than with other shock absorbing solutions. I do wanna point out that the average break-in period for this hitch is gonna be about 1,000 miles. And this does feature a powder coat finish that's going to resist wear and corrosion. And as you might know, Gen-Y has a great reputation of designing and building very robust products, very durable products, and I'm happy to say that this is no exception to that. I think this is going to hold up really well for you. This is going to be a great investment for you to consider. Well, I think that's gonna wrap up our look today. I do hope that our time together has been helpful for you. Again, my name is Andy. Thank you for joining me.

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. 3.5K pin weight.The Gen-Y hitch is very stout & well built. Fit & finish was excellent.
Installed myself in about 30 minutes.
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.
The box for the hitch was absolutely destroyed, the hitch has damage to the powder coat on most sides. Almost no packaging in the box, not sure how you guys pack these but this $[XX] hitch is beat up pretty bad. Really disappointed and i don't have time to had it repowder coated as i am picking up the new camper tomorrow with this hitch and now this one is going to rust.
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.
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 provided the specs on my 5th wheel (Grand Design Momentum 351 MS) when ordering the pinbox. I had the Gen-Y pinbox mounted and used it for about 5-months to find later that the pinbox was not the proper pinbox for my 5th wheel while having Independent Suspension installed. I replaced the Gen-Y with a MoRryde pinbox while at MoRrdye. Not a good experience and a loss of funds.
Great product. The fit and finish is perfect. The trailer tows so much smoother and the chucking is almost gone. The extra bed space is a great bonus.
Invoices were confusing. They said I was getting two Gen Y hitches? Then when it actually came down to tracking it appeared I was getting the wrong one. Afte a few emails and phone calls, Will did get that cleared up. Then they shipped my chains to someone else and I got their package, an awning support bracket of some sort. Again a few emails and phone calls Will did get this cleared up as well and shipped the chains to me, but I had to make a trip to the UPS shipper to get the awning support back to them. Real roller coaster...
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!
Simple design, very robust construction, made a vast improvement in towing ride quality.
Easy install by myself, Engine hoist, utility cart and motorcycle jack...ya I have "stuff".
I will need to lower my B&W slide about 2inches to get back to level towing. Calculator that Gen Y has for selecton is spot on , I was a bit worried as my measured tounge weight was 2700 +/- lbs 22% of GVWR (14,400) was 3168 so I ordered the 4.5k model
When hiched for the first time...indicator was in the middle of the green (perfect).
Very happy ... next Im adding shock absorbers to see if i can smooth the trailer hop a bit more.
Hands dow the best Fifthwheel hitch you can buy. I had this hith over a year now and is the best one i ever had.
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!!!
I installed the unit today. It appears to be well built. You should note that it is very heavy compared to a Rhino Box (120# v 50#). I inserted the pin box onto my fifth wheel hitch and then backed into place to mount it on the camper making it a one person job.
Some items to note…hardware is not included. GenY recommends grade 8 bolts. The original hardware was grade 5 on the rhino box. Also, I don’t like to retension high strength bolts, so I would recomend new grade 8 bolts. The rhino only had 10 bolts where I could get 12 in this one. Also note that the tag on the actual pin box says only good for 18000lbs (not 21000 as advertised). The tongue rating was as advertised 3.5k model) My camper is smaller so the 18000 lbs isn’t an issue.
Haven’t actually road tested yet, but I am confident it will improve ride.
Thank you for helping me choose the hitch I needed. My thought was to use an air bag system, but we found it was not available for my trailer. We then looked to the Gen-Y and fell it will do the job, and at less cost!
After one year our Gen Y hitch works as it should. The shipping process was a problem and I blame that on the rail and freight companies. I highly recommend
Ordered a gen y goose neck hitch for my trailer and did not put on right away, but once I did I realized that it was not the correct one per the hitch weight and overloaded empty ont the truck. I contacted etrailer via email just to get told it's been almost a year since I bought the hitch and basically we can't do anything. I gave etrailer the exact model and Vin when I ordered.
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...
I would recommend the Gen Y hitch to my friends. It absorbs a lot of the shock that is transferred from the trailer to the truck.
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
Does a fantastic job. After 4 or 500 miles the ride quality smoothed out considerably. Extremely well built!!
So far this hitch has been wonderful. We were fortunate enough that one of the hitch reviews on YouTube was on a DRV fifth wheel similar to ours and so we ended up going with the exact same hitch. The sample mathematical equation used to figure out what size hitch one would need, just didn’t work for us. It was trying to get us into a heavier duty hitch than what was needed. My advise? Gain knowledge of your actual pin weight and then buy accordingly. It’s a five star product!
Arrived as expected and had the installation completed in about two hours. My expert salesman saved me alot of misery because I had intended to order the wrong hitch and he corrected the error. Excellant service and really refreshing to work with people who really care.
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.
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
