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 may be shorter than the Fabex 665 or M&M 665 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

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.


Easily Check Your Vertical Load

scale

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 scale so that you can check to see if your vertical load is too high or too low. The red section on the top of the scale indicates your maximum vertical load (5,500 lbs). The red section on the bottom of the scale indicates no vertical load (0 lbs). For the built-in shock absorption to function effectively, the scale's white indicator marker should be within the green section when you hook up your trailer to tow.
