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.


Unlike other shock-absorbing solutions on the market, this one is easy to maintain. Just regularly apply grease to the built-in zerk to keep the components in working condition. No airbags to fill. No small parts to repair or replace. No hassle.


Easily Check Your Vertical Load

Executive scale

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 (3,500 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.
