    • Technology functions like a torsion axle to limit transfer of road shock from trailer to truck and vice versa

    • No airbags to maintain and fewer moving parts to repair or replace than with other shock-absorbing solutions

Specs:

  • Towing capacity: 21,000 lbs
  • Pin weight capacity range: 1,500 lbs - 3,500 lbs

Notes:

  • Average break-in period for hitch = 1,000 miles.
  • 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 1716 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.

  • 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.

  • 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 it's in the 1,600-2,599 lbs range you need the box # GY35FR...
