Notes:
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.

Installed on my 2018 Grand Design Momentum 395m 3 axle toy hauler. Immediate improvement with chucking. This should help with any FRAME FLEX that you hear so much about. Fingers crossed.
I would rate it a 5Star, on the customer service and the delivery. I was also impressed that it was delivered on or very close to the date given at time of order.
Haven’t towed it yet with the new equipment installed. Will be towing it next week on Tuesday, looking forward to it. Will go back and leave comments on how it does.
This hitch makes towing our 44ft toy hauler a pleasure
This pinbox fixed two problems I was having. I can know turn 90 degrees and I have up to 10 inches of clearance from top of bed rail to 5th wheel overhang
Install went smooth. I'm 75 and with a small car jack on my truck tail gate it went very quickly. Blocked the pin end on bed so it wouldn't tip and jacked up the back. Got one rear hole lined up bolted and then just jacked up the pin end and put those bolts in. I will hook it up today and see how it sets. Might have to lower my truck hitch one notch if it sits too high - we will see. ( Momentum 395 MS/ F350)
Excellent hitch, rides smooth and quit e.
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.
Thank You for your interest in my experience with the Gen-Y King PIN Hitch I purchased last year. I love the Gen-Y KP Hitch. The torsion mechanism has significantly smoothed out the ride compared to the standard Lippert King KP Hitch that came standard on my Grand Design Reflection 340RDS 5th Wheel. I also like that the Gen-Y KP Hitch is 4" shorter than the Lippert KP Hitch as I get a little more turning radius with my short bed Ram. Also, the contour of the Gen-Y KP Hitch allows a little more clearance over the top of my Gator Tonneau Cover Rails v.s. the Lippert KP Hitch.
Now for the "not so good" news about my purchase experience. The packaging of the Gen-Y Hitch was way below the quality standard I would expect from E-trailer. Please see attached file.
I'm sorry I did not send you this information regarding the poor packaging and subsequent minor damage to the Gen-Y KP Hitch which I was able to correct upon install of the Hitch. Last year was very busy for me and I was not able to send this information sooner.
Super fast shipping. Easy install. Heavy buggar so hired two young ones to hold it while I bolted it into place. Coming up into the 1000 mile usage mark and it is doing its job well absorbing road shock. In New York state now. PA roads are awful bumpy so it got several good tests.
So far so good. More to share after break-in period.
On a +~3.5K mile round trip this last spring, this pin box provided greater stability than the original. There was a substantial reduction in porpoising along with smoother recovery from pot holes/irregularities, however there still remained a slight “chuck.” Overall, a better design.
Thule products are built to last decades. So a year later, this is every bit as great as the day I installed the crossbars on my roof.
Works great, easy to install and uninstall if you don't want to keep it on all the time. Take some time to put the rubber (on the bar that isnt on this product) on correctly the first time, as its a little trickier if you mess it up and have to do it again. We have put our 16' kayak on many times with no issues.
The hitch bolted up easy, and seems to react well between the truck and 5th wheel
Etrailer is an awesome website. They are very responsive to questions. Installation was simple and straightforward. I have not towed with this new pinbox as my rig is bedded down for a long winter nap in the northeast.
I went from a standard stock hitch to the gen Y. The difference is just amazing. When I get a new 5th wheel I will definitely be getting Gen Y again. I have zero complaints.
It's been rock solid on my 2022 Sorento PHEV. I combine it with a hitch rack, so it's nice that I can easily remove and reattach quickly. I haven't noticed much wind noise or increase in MPG like I did with an old rack+fairing.
Thanks again for the excellent, professional, knowledgeable customer service. It is refreshing to be able to talk to someone who is friendly and glad to help with specialized needs such as racks, hitches, etc. You won't find that kind of service in a lot of places. That is why I recommend etrailer to all of my friends.
The 2022 Hyundai Santa Cruz is getting very popular and lots of people are wondering when a truck rack, or ladder type rack will be available for it. It is a great truck but the roof does not allow larger items like longboard surfboards or SUP boards or kayaks to be installed on the roof. There just is not enough room for standard surfboard racks to be spread out long enough to safely carry these longer items. Thule says 27 1/2" is the standard distance between bars but all of us surfers, windsurfers know that one needs more distance between the crossbars to carry a 9' surfboard or greater. I was going to use the Thule racks I just ordered on my 2022 Hyundai Santa Cruz, but it seems there is just not enough room on the roof to get the distance needed. Plus, the roof is kind of rounded toward the front so the front bar will be down at an angle. I ended up putting the rack on my Hyundai Tucson. So, there is a need out there for a different system for the Santa Cruz. Any advice on a roof rack for the Santa Cruz would be appreciated. Maybe I am looking at it wrong and I don't need as much room on the roof as I think to transport a longboard. I know there is a lot of discussion on this subject on the Santa Cruz forums online. I use a 9', and 10' longboard (surfboard).
Fit was correct and the attachment is solid. Seems expensive for the content,
But it works.
I love my hitch
Everything came quickly and all at one time. The instructions were clear, communications were frequent, and follow-up was immediate. Fantastic customer service combined with great and easy selections.
