Gen-Y Hitch 5th Wheel Pin Box - GY68GR

  • Lippert 1621
  • Lippert 1621HD
  • Upgraded Pin Box
  • Absorbs Road Shock and Reduces Chucking
  • Gen-Y Hitch
  • 30000 lbs GTW

This shock-absorbing pin box provides a smooth, safe ride while you tow your fifth-wheel trailer. The all-in-1 box has no air bags to refill or small parts to replace. 4.5K Pin weight.


Features:

  • 5th-Wheel king pin box upgrades the existing pin box on your 5th-wheel trailer
    • King pin inserts into your truck's 5th-wheel hitch
  • 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
  • Heavy-duty steel construction
  • Powder coat finish resists wear and corrosion
  • Simple, bolt-on installation
    • Mounts with existing bolts
  • Made in the USA


Specs:

  • Designed to replace Lippert 1621 or 1621 HD 5th-wheel pin boxes
  • Towing capacity: 30,000 lbs
  • Pin weight capacity range: 2,000 lbs - 4,500 lbs
  • 5-Year limited warranty


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.
  • To calculate correct pin weight for Gen-Y hitches, use this formula: GVWR x 0.22
  • 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.

Calculated Pin Weight Executive Pin Weight Capacity Required
1,600-2,599 lbs 3,500 lbs
2,600-3,599 lbs 4,500 lbs
3,600-4,599 lbs 5,500 lbs
4,600-5,599 lbs 6,500 lbs
5,600-6,599 lbs 7,500 lbs

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 Shock Absorbing 5th Wheel Pin Box For Brinkley 5th Wheel With 18K GVWR
    Hello Donnie, thanks for getting in touch. The Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # 325-GH-8040 may work for your camper. This model is designed to replace the Lippert 1621 and 1621 HD pin boxes. There is no way for me to look up what pin box your camper is currently equipped with, so this is something you will need to confirm. There should be a sticker on your pin box that has the brand, model number, serial number and it may even have the pin box size number. If the size is...

  • Can Gen-Y Pin Box Replace Lippert 1621 SHD 21K for Better Clearance
    Thank you for the information and photo! I was able to determine that you have a 1621 SHD (super heavy duty) pin box rated for 21K. The Gen-Y equivalent is found as part # GY68GR for a 4.5K tongue weight or part # GY46FR for a 5.5K tongue weight. While these are excellent replacement options in and of themselves, if the clearance issue is between the cab on your 2021 GMC Denali and the box on the 5th wheel trailer we'll need to go with the MORryde Cushioned 5th Wheel Pin Box # MR24VR instead...

  • 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...

  • How To Determine What The Bolt Pattern Of Your Trailer's Pin Box
    The only way to determine what your pin box's bolt pattern is would be to either get the serial number/RPO number off the tag on the pin box or to use the attached guide below to measure the bolts and crossover those measurements on the included charts to determine the pattern. Once we have the bolt pattern we can then find the correct replacement depending on what you're needs are. If you experiencing side-to-side, front-to-back, or up-and-down motion from your trailer then we have different...

  • Switching From Curt A25 With MORryde Pin Box To B&W Companion With Gen-Y On a 2023 GMC Sierra 3500
    First be sure to check the mounting points of the MORryde Cushioned 5th Wheel Pin Box # MR84VR to verify it cannot be moved lower on the mounting arms which would give you the rise you are needing. If the pin box is already in its lowest position the B&W Companion OEM 5th Wheel Hitch # BWRVK3715 is capable of a height of 18-3/4". This has the same 25,000lb capacity of your Curt A25 # C24FR. The MORryde # MR84VR allows for front, back and side to side cushioning to reduce chucking while...

  • Trailair Flex Air 5th Wheel Trailer Pin Box Comes Into Contact with Bed Sides
    I do have an option for you but continually raising the trailer is not a good idea if you are already level as the more nose high you are, the worse the trailer will pull. That said, we do recommend between 4-6" of clearance from the trailer to the bedside. If you don't have this then you will need to raise the hitch height until you do. If the trailer starts to become nose high then you'll need to raise it using a kit like the Correct Track Trailer Alignment and Lift Kit part # RR23QX. If...

  • Recommended Gen-Y Pin Box for a 2018 Grand Design Solitude
    Tim, thanks for all the info. I was able to get that over to Lippert and they let me know that you have a 1621 pin box so the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # 325-GH-8040 for a 21K or the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # GY68GR for a 30K would work.

  • What Gen-Y Pin Box Will Fit My Brinkley 3610 5th Wheel 18,000 lb GVWR?
    Hello Donnie, thanks for getting in touch. A Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box may work for your camper. Since your GVWR is 18K, you will want to go with the 4.5K model like # GY68GR. The GEN-Y 325-GH-8040 you mentioned is not rated quite high enough for your camper. This model is designed to replace the Lippert 1621 and 1621 HD pin boxes. There is no way for me to look up what pin box your camper is currently equipped with, so this is something you will need to confirm. There...

  • Will GEN-Y Shock Absorbing 5th Wheel Pin Box # 325-GH-8040 Replace MORryde SPB72-1621HD?
    Thanks for the picture, Chad! The GEN-Y # 325-GH-8040 you were looking at is a direct replacement for your current MORryde # SPB72-1621HD. The only thing you'll need to make sure of is that the pin weight of your trailer falls between 1500-3000lbs to match the cushioning offered with this pin box. If your pin weight falls in this range, you're good to go! Though if you have higher pin weight you'd probably need the # GY68GR which works with up to 4,000lbs pin weight. If your not sure...
