Features:

  • 5th-Wheel-to-gooseneck adapter box lets you tow your 5th-wheel trailer with your gooseneck hitch
    • 5th-Wheel pin box replaces the factory pin box on your trailer
    • Coupler attaches to your truck's gooseneck hitch ball
  • 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
  • Self-latching lever automatically engages when hitch ball is in socket
  • Cable latch allows you to easily uncouple from outside of your truck bed
    • Included cable attaches to lever - just pull on it to disengage the latch

    • Meter lets you know if your load needs to be adjusted before you tow
  • Cross-shaped holes provide attachment points for safety chains
  • Heavy-duty steel construction

  • Towing capacity: 25,000 lbs
  • Pin weight capacity range: 3,500 lbs - 5,500 lbs
  • Ball size: 2-5/16"
  • 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.
  • 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.

  • Fifth Wheel to Gooseneck Adapter

    Say your truck has a gooseneck hitch for towing your horse trailer, but you want to go camping with your new fifth wheel. You could outfit your truck with a new fifth-wheel hitch that attaches to your existing gooseneck hitch, but that means having to move a heavy, bulky hitch into and out of your truck bed all the time.


    You could also purchase an adapter that bolts onto your trailer's existing pin box. But adding a new component to your setup can keep your pin box from working how it was designed. King pin adapters can create a stiff ride and can even strain your fifth wheel's frame by adding too much height at the connection point.


    A better option is to use this gooseneck-compatible pin box to easily tow your fifth-wheel trailer with your truck's gooseneck hitch. The box replaces your trailer's existing pin box, which means it's designed to act as a part of your trailer instead of simply bolting over your king pin like an adapter does.


    Built-In Shock Absorption for a Smooth Ride

    Executive torsion with cable

    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 adapter. This allows for movement between the box, which attaches to your trailer, and the coupler tube, which connects to the gooseneck hitch ball in your truck bed. When your trailer bounces or jerks, the coupler tube 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 coupler end moves, these inner bars twist inside of the tubes, attempting to follow the coupler'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.


    Easy to Couple and Uncouple

    auto latch and cable

    The Gen-Y pin box adapter makes hooking up your trailer easy thanks to its automatic latch. When your hitch ball moves into the coupler tube, the latch instantly engages. No need to manually close the socket once the coupler is on the ball.


    Disconnecting is fast and easy too. This normally requires that you crawl into your truck bed to access and release the latch. But the Gen-Y adapter box can be disconnected from outside of your truck bed. The included cable attaches to the latch on the coupler's base. Just run the cable up your trailer frame and secure it in a convenient place. When you're ready to disengage the coupler, simply pull the cable to release the ball from the socket. No need to climb into your truck bed.


    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 ball 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 (5,500 lbs). The lowest arrow indicates no vertical load (0 lbs).

    Very good company to work with, I had a different hitch on order, they communicated to me that the item would be back ordered for a time, I then picked a different hitch, they immediately gave me credit for the first one, and shipped the new hitch. Would recommend this company for all your trailering needs!

    I put a flatbed on my truck so I could load my side by side and go wherever we want. This meant I had to figure out a new way to pull my toyhauler. I had a ford factory fifth wheel prep package with the reese hitch. With the flatbed I cant use this hitch anymore. I was planning to use the Anderson ultimate fifthwheel hitch but would have to change the pin box on my toyhauler as well since it was a flexair and Anderson says not to use a pin box that pivots. Sooo......I started searching for a new pin box and came across this hitch. This solved all my problems! Don't need an Anderson hitch as this pin box will attach to the ball on my flatbed. I called and talked with Chrissy who was super helpful. I ordered the pin box and it arrived yesterday. With some help I got it installed in less than an hour. (2 or 3 person job). It looks great and I'm excited to test it out. Fast shipping and great packaging. Thanks etrailer.com!

    Review from a similar Executive King Pin in Gooseneck and Fifth Wheel Adapters


    Installation was very straight forward, it is heavy so you need something to prop it up for you while you get at least one bolt started in each side. I used the bucket on my tractor to hold it up. I only have one tow in so far for about 50 miles so still early to review. It certainly works as advertised for taking out a lot of the trailer feedback on rough roads, uneven transitions, etc. It is an improvement in ride quality and makes towing a big fifth wheel more comfortable. Necessary? Probably not but it does spoil you a little bit. One problem though that Gen-Y is working on fixing is the ball to pinbox is a little bit longer and I did hit the bed cap at about 60 deg of turn while backing in at an angle. It cleared when I tested it in the flat driveway, but not by much. They are going to come up with a fix. I'm at 7 1/2" clearance from the overhang to the bed caps sitting flat. This is with a '18 Chev Silverado HD 8' bed and a '19 Momentum 351M
