Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Have had issues your trailer bouncing and want to soften the ride so you don't feel tossed around in your truck
  • Tow a very heavy trailer or toy hauler with a pin weight between 2,000 and 4,500 lbs
  • Have no patience for filling up an air bag every time you hit the road

No, if you:

  • Haul your trailer with a truck that sits high - this pin box adds some height which can cause chucking if you can't adjust to compensate
  • Have a short bed truck or a toolbox and need a pin box that gives you more clearance between your truck and trailer
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.

Features:

  • 5th-Wheel king pin box upgrades the existing pin box on your 5th-wheel trailer
    • King pin inserts into your truck's 5th-wheel hitch
  • Shock-absorbing design ensures a smooth, steady ride
    • Technology functions like a torsion axle to limit transfer of road shock from trailer to truck and vice versa
      • Reduces chucking and rough fore-and-aft motion
      • Limits bounce and jarring up-and-down motion
    • No airbags to maintain and fewer moving parts to repair or replace than with other shock-absorbing solutions
  • Pin weight scale is built in to help you balance your trailer
    • Meter lets you know if your load needs to be adjusted before you tow
  • Heavy-duty steel construction
  • Powder coat finish resists wear and corrosion

Specs:

  • Designed to replace Lippert 1621 or 1621 HD 5th-wheel pin boxes
  • Towing capacity: 30,000 lbs
  • Pin weight capacity range: 2,000 lbs - 4,500 lbs
  • 5-Year limited warranty


Notes:

  • In order for the pin box's shock absorption to work correctly, make sure your pin weight is within the pin weight range.
  • To calculate correct towing weight for Gen-Y hitches, use this formula: GVWR x 0.22 = TW.
  • Because the Gen-Y Hitch Executive is shorter than the Lippert 1621 or 1621 HD pin box, the clearance between your trailer and tow vehicle during turns might be reduced.

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.


Easily Check Your Vertical Load

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.

Video Transcript for Review of Gen-Y Hitch Fifth Wheel King Pin - Upgraded Pin Box - GY68GR

Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at the Gen-Y Hitch shock absorbing 5th wheel pin box for the Lippert 1621 and Lippert 1621 HD pin boxes, and this has a 30,000 pound gross towing weight capacity. Now, this 5th wheel king pin box will upgrade your existing Lippert 1621 or 1621 HD pin box that's on your 5th wheel trailer. Basically, it will replace the factory pin box. And then the king pin right down here, this is what'll insert into your truck's 5th wheel hitch.

This pin box here uses a nice shock absorbing design, which ensures a nice, smooth, steady ride. The technology on this functions just like a torsion axle and limits the transfer of any road shock from the trailer to your truck and vice versa. Did wanna pop up an insert there just to show you the how the inside construction looks like on these. But we've mentioned it's like a torsion axle, so basically, on where these bolts are, there's four different tubes here and they have outer tubes. And on the inside, they have rubber cords around the inner bar, and that will reduce the chucking and the rough fore and aft motion.

It also limits any bounce and jarring up and down motion. And what's nice about this design, there's no air bags that you have to maintain. And they do have fewer moving parts to repair or replace than with some of your other shock absorbing solutions. This one does offer the nice pin weight scale, which is noticeable on this lower arm here. It's built-in to help balance your trailer.

That scale will let you know if your load needs to be adjusted before you tow. Basically, the vertical load or the pin weight, that'll refer to the weight that a fully loaded trailer will exert downward on your hitch in the truck bed. And, of course, too little vertical load can cause trailer sway, too much will give you poor performance. So, let me just zoom in. And there you can see, right there on the lower arm, I can point to it.

There's your scale here. If you notice the scale here has a red on each end. Up at the top is the maximum, the very bottom is the minimum, and there's green in the middle. The red areas, at the top, that's too high, then the bottom is too low. So, you want your white indicator line right over here pointing into that green area. The maximum red will indicate the maximum vertical load of 4,500 pounds. The minimum red area indicates no vertical load. So, you do wanna be in that pin weight range of 2,000 to 4,500 pounds for this to work correctly. They do recommend a vertical load of at least 2,000 pounds because this built-in shock absorption is designed to function effectively by at least having 2,000 pounds vertical load. Now, this is a nice, heavy-duty steel construction. Has a nice powder coat finish on it to resist wear and corrosion. It is a simple bolt-on installation. These mounting holes do line up to the factory holes, and they will mount with your existing pin box bolts. This part is made in the USA. And again, the specs on this, the towing capacity we mentioned is 30,000 pounds. But that should do it for the review on this Gen-Y Hitch shock absorbing 5th wheel pin box for the Lippert 1621 and Lippert 1621 HD pin boxes..

Excelent king pin hitch, it takes 99% of the chucking out of the 5th wheel hitch.

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.

  • Can Gen-Y Pin Box Replace Lippert 1621 SHD 21K for Better Clearance
    Thank you for the information and photo! I was able to determine that you have a 1621 SHD (super heavy duty) pin box rated for 21K. The Gen-Y equivalent is found as part # GY68GR for a 4.5K tongue weight or part # GY46FR for a 5.5K tongue weight. While these are excellent replacement options in and of themselves, if the clearance issue is between the cab on your 2021 GMC Denali and the box on the 5th wheel trailer we'll need to go with the MORryde Cushioned 5th Wheel Pin Box # MR24VR instead...
