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.
The vertical load, or pin weight, refers to the weight that a fully loaded trailer exerts downward on the hitch in the truck bed. Too little vertical load can cause trailer sway and too much can cause poor performance.
This Gen-Y pin box has a built-in mechanical scale so that you can check to see if your vertical load is too high or too low. The highest arrow on the scale indicates your maximum vertical load (4,500 lbs). The lowest arrow indicates no vertical load (0 lbs). A vertical load of at least 2,000 lbs is recommended for the built-in shock absorption to function effectively. This means that the scale's white indicator marker should be between the highest arrow and the middle arrow when you hook up your trailer to tow.

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. Weight scale lets you monitor your vertical load. 4.5K Pin weight.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.
Just got my gen y king pin delivered today. It took 4 old men 1 hour to put on using my truck and hitch. Easy installation. I’m a full timer so next month we will see how it rides. I got the gen y because it is 3 inches lower than the rotoflex. It shouldn’t hit my tonneau rails. I’m anticipating being Abe to turn 90 degrees without the pin box hitting my side rails. And it looks tough.
The benefits of an airbag hitch without the worry of air leaks. Drastically improves the the ride and drivability.
Thanks Gen-Y and etrailer
WOW Not that I am surprised. etrailer knocked it out of the park again. From the knowledgeable fast and professional help from Representative Joanne K. My buying experience felt like I was buying from a friend. But then after the sale the follow through was unmatched. The GEN Y pinbox I ordered was not in stock but became available much earlier than promised and I got an email notifying me that in was in and being processed. Another letting me know that the item had shipped. Item arrived on time and very well packaged.Excited about getting the pinbox installed I was on my own with no one around. The install went Smooth and easy. Buying from a company that really cares about their costomers is getting to be such a rarity but etrailer went over and above to make my purchase fantastic. The GEN Y pinbox is well made and the fit and Finnish is beautiful. I can't wait to take it on our next trip.
Excelent king pin hitch, it takes 99% of the chucking out of the 5th wheel hitch.
The quality of the pin Box is very good. I am very disappointed in the load carrying ability. The first 300 miles the indicator wa in the center of the green since then it stay's in the red. My TW is right at 3500 pounds.
Price was great, web site and all info was easy!!
I haven’t used it yet but I’m excited to give a try. I’m hoping this will give me the clearance I’m looking for on my F-450. A big thank you to Sheryl H for all the help with ordering the right one and keeping me up dated all the way through delivery. She did an amazing job.
Fast shipping easy to install. My son does MX racing and we put 500+ miles on it every race. Definitely need some muscle to lift it but really simple and fast (took my son and I less than 15 min at the track) to install and noticed a huge difference in the ride.
Package real good hard to get the stuffing around it loose need a new shipping company the one you have don’t make deliveries when they schedule them make people wait not yet taking the protection off it
