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.

  • Shock Kit And Gooseneck Pin Box For 2024 Brinkley Z3110 5th Wheel
    Hello Stephen. The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks # RM-2460-2580 will work great on your 2024 Brinkley Z3110 5th wheel since it has 3" diameter axles. The Comfort Ride kit will make huge improvements in ride quality and stability. A Gen-Y shock absorbing pin box will also help with ride quality since they use torsion rubber to absorb shock.

  • Will Additional Length of Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box Impact Clearance
    Hi Blake; the additional 3-3/4" will actually increase clearance since the trailer will sit a little further back. If it was shorter and brought it closer to the cab clearance would become a concern. The # GY43GR is the 5.5k tongue weight model so make sure your GVWR x 0.22 = 3,600-4,599 lbs. If you have a different calculation you will need a different model and can choose from the following: -Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box - Lippert Rhino - 21,000 lbs - 3.5K TW # GY86GR...

  • Replacement Gen-Y 5th Wheel Pin Box For A Lippert Rhino Bolt Pattern
    Thank you for all the info John, Based on the numbers you provided your pin box has a Rhino bolt pattern with a 21,000 capacity. To find the correct Gen-Y pin box we'll need to check your trailer's pin weight. If the pin weight ranges from 1,600lbs - 2,599lbs then you'll need part # GY86GR. If your pin weight ranges from 2,600lbs - 3,599lbs then you'll need the # GY78GR. If your new Silverado has a short bed as well then you may need to swap out the base on your Curt A25 with a sliding...

  • Recommended Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box to Replace a Lippert Rhino
    No, it does not but I have one that does. It is the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box item # GY86GR. This pin box is custom designed for the Lippert Rhino bolt pattern. It has an identical 21,000 lbs towing capacity and a 3,500 lbs tongue weight to the one you were looking at. The Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box item # 325-GH-8040 you were looking at fits the Lippert 1621 and 1621 HD pin boxes.

  • Will The Gen-Y 5th Wheel Pin Box # GY86GR Work With A Flatbed Truck With A Recessed Hitch Ball
    Hi Rick, The Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # GY86GR could potentially work but you'll need the correct gooseneck to fifth wheel hitch adapter or you'll want to switch to a gooseneck pin box like # GY98GR. The # GY86GR is designed to couple up to a 5th wheel trailer hitch and with you having a recessed ball you'll need one like the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter for Recessed Ball # DM8550046.

  • Recommended Pin Box for a 2015 Prime Time 28RL Crusader 5th Wheel
    Hey Greg! Thanks for the information but I wasn't able to find that 352144 part number anywhere let alone corresponding to a Lippert 1621 pin box. I would need to see the sticker on your Crusader's pin box so I can call Lippert and verify which bolt pattern you have. You can send it to me directly at the email address you receive this one from.

  • Can You Make 90 Degree Turns with Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box for Lippert Rhino
    The Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box part # GY86GR isn't designed to be any longer than the pin box it replaces. I have attached the dimensions below so you can be sure but if you couldn't make full turns before, odds are you won't be able to with the new pin box. If you could make full turns before then you should still be able to do so with the new pin box. The pin box is designed as a cushioned replacement which will help improve ride quality. If you want to gain turning...

  • Which Gen-Y Fifth Wheel to Gooseneck Adapter Fits Brinkley 3610
    Hey Ryan, since in the past we have determined that your Brinkley 3610 has a Lippert Rhino Box pin box the correct Gen-Y fifth wheel to gooseneck adapter would be the part # GY98GR. If you were looking for a cushioned pin box instead you'd need the # GY86GR.
