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 Breaking Down the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box

Hello everybody. This is Jeff at etrailer.com. 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..

See what our Experts say about this Gen-Y Hitch 5th Wheel Pin Box

  • Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box For an LCI Frame 336772
    Trevor, according to Lippert you are going to have an 1116 pin box on your 5th wheel. This means you would need to select one of the following Gen-Y Hitch Shock Absorbing 5th Wheel Pin Boxes from the list below depending on your trailers tongue weight. 1,500 lbs - 3,500 lbs # GY35FR 2,000 lbs - 4,500 lbs # GY45SR 2,500 lbs - 5,500 lbs # GY23FR The Hitch # GY43GR you found will not fit on your mounting arms as it has a much different bolt pattern and width.

  • Recommended Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box For A Genesis Supreme GCK405
    The Lippert 127027 comes up with an 1116 bolt pattern so you'd need to pick one of the following options depending on your trailers pin weight: Pin Weight: 1,600-2,599lbs # GY35FR 2,600-3,599lbs # GY45SR If you look at the front driver's side of your trailer there should be a sticker that lists the GVWR and Pin Weight so that you can choose the correct replacement.

  • How to Tell if Gen-Y Executive Pin Box Will Have Same Clearance as Lippert 1716 Pin Box
    For your application you need the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # GY45SR rated for 4.5K tongue weight. To check how this will fit with your current setup you'll need to compare the location of the bolt holes to the king pin and how those compare to your current pin box: - Top hole to king pin plate is 12.786" - Front row of bolt holes to middle of king pin is 17.122" We don't list out truck dimensions because those can be found either on the truck manufacturer's website...

  • 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...
