Expert Answers about Gooseneck Coupler


  • Is 3/4 inch of Vertical Play Too Much in a Bulldog Gooseneck Coupler
  • I spoke with my contact at Bulldog and he informed me that 3/4 inch of play would be quite a bit of movement and that something would need to get replaced. There are a few components that can contribute to movement (gooseneck hitch, gooseneck ball, gooseneck coupler and gooseneck vertical tube) so it’s hard to say how much all together all these components might add up to with allowable tolerances and then wear that might be expected over time. Your best option would be to try to find...

  • Troubleshooting Alignment of Gooseneck Coupler with Inner Tube Replacement
  • The B&W Extend-A-Goose Gooseneck Coupler - 10" Offset # BWTEXA4200 should be a straight fit. If your coupler was not installed so the pin was horizontal, then there isn't another adapter that will fit correctly. The misalignment will be an issue with any replacement. I recommend replacing your coupler with the Ram Gooseneck Coupler w/ Load Bearing Pin - 8" Adjustment - Round - 2-5/16" Ball - 25K # GCPN-25008. Your only other option is drilling a new hole in your current coupler to...

  • Gooseneck Makes Clank Sound Taking Off or Stopping
  • It seems like this could be more of an issue with your coupler than your B&W Gooseneck Hitch # BWGNRK1111 itself, since that's what grabs the ball. Check the coupler to make sure it's operating correctly. You should also inspect the ball to make sure that it's not damaged. If it is, you can replace it with the B&W Replacement Hitch Ball for Turnoverball Hitches # BWGNXA2000 . If the coupler is damaged, you may be able to replace just the inner tube, but it could also require a full replacement...

  • Is Creaking or Popping Noise Normal for Convert-A-Ball Multi-Cushioned Gooseneck Trailer Coupler
  • The Convert-A-Ball Multi-Cushioned Gooseneck Trailer Coupler # CG itself shouldn't be making any kind of creaking or popping noises when you're breaking and accelerating. The only way something like that would be possible is if the internal components failed and in that case they would be falling out of the bottom portion of the coupler, according to my contact at Convert-A-Ball. You might get a little creaking from the gooseneck hitch ball connection to the coupler if you go over a speed...

  • Replacement Adjustment Handle for Ram Adjustable Gooseneck Coupler GCSQTW-30008
  • If the coupler will not adjust be sure that the set screw (shown in the linked photo) has been loosened to allow the coupler to move. If the set screw has been loosened and the unit will not adjust try applying a product like PB Blaster or WD40 to the set screw hole with the unit upside down so that it can flow down into the mechanism. This might help loosen up the adjustment function. If you need just a Replacement Topwind handle assembly for your Ram Adjustable Gooseneck Coupler # GCSQTW-30008...

  • On the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR, there is a set screw in the block so it should be adjustable. See attached engineering design.

  • Troubleshooting 40ft Gooseneck Trailer Vibrating Loaded and Unloaded
  • If you are getting constant vibration when towing your gooseneck trailer then it is likely that one or more components of the suspension is in need of replacement and/or your axles are out of alignment. Start off by checking your suspension components making sure that they are all in good working order. I have attached a link to our selection of suspension components as well as a trailer maintenance schedule for you to check out. To determine if your axles are out of alignment you will...

  • Rapid Hitch Universal Coupler Adapter # AM3100 Will not Release from Gooseneck Ball
  • We have not received any reports of the Rapid Hitch Universal Fifth-Wheel-to-Gooseneck Coupler Adapter, # AM3100, not releasing from a gooseneck hitch, but the cable release system for the pin that secures the adapter to the hitch ball is a pretty simple set up and should be easy to troubleshoot. I would recommend removing the four bolts on the housing that the cable is attached to. Once removed, you will see a small cable attached to a metal plate. There could be two issues here, either...

  • Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter RP94720 Wont Take Air
  • Thank you for your recent purchase of a Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR. Some air chucks - the chuck is the valve on your compressor or other air pump - will have a size/shape that will not be compatible with the inflation valve on your Reese Goose Box. Some chucks have a shape that will prevent close enough contact to fully depress the pin inside the bag's inflation value. This would block air flow. Another less likely possibility is that there...

  • How Can I Keep My Trailer From Riding Nose Up
  • If your trailer's gooseneck hitch is in the lowest possible position, you may be able to replace it with something with either more adjustability or has a lower profile. The Pro Series 25K Gooseneck Plate for Fifth Wheel Rails by Draw-Tite, Hidden Hitch and Reese, part # 16055, will work. It has a 2-1/2" rise from the truck bed to the base of the hitch ball. Your existing gooseneck trailer hitch, part # 16085 has slightly more than 3". If this will not work, you will have to raise your...

  • How to Lock Trailer that has a Reese Goose Box
  • The design of the Reese Goose Boxes like # RP85FR prohibits the use of locks designed for standard gooseneck couplers. They cannot grab onto the coupler like they are supposed to. To secure the trailer a wheel lock such as # WI490 or # RA-25 or something similar is recommended instead. I have linked some videos on these locks for you. These lock the wheels of the trailer instead which is a very effective theft deterrent.

  • Fifth-Wheel To Gooseneck Coupler Adapter Will Not Release From Gooseneck Ball
  • If you are using the remote and cannot seem to get the adapter to release you may want to loosen the four screws on the remote box to make sure it is working properly and releasing the adapter from the goose ball. You will want to try and make sure the truck and trailer are on a level plane when trying to get the adapter to release.

  • Repair Kit for Release Mechanism of Reese Goose Box Trailer Coupler
  • A Reese Revolution pin box does not have a release cable but their Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapters, such as # RP85FR, do have a release mechanism consisting of a cable and actuating arm. Please refer to the linked photo. My contact at Reese advised that failures of the release are quite uncommon but we do have a repair kit that consists of a shaft, arm and hardware, part # BD1542S01.

  • Troubleshooting Loose Gooseneck Ball on 2019 Ram 3500
  • There shouldn't be any significant "slop" or play with your Curt Ball # C60618. It sounds like once you lock the ball in place with the integrated lever you are still able to move it quite a bit. However, a little bit of movement is normal. If you watch the installation video for the Curt ball below starting at the 1 minute mark, you can see how much movement is normal. If it is moving enough for you to hear and feel a "thunk" it sounds like the ball might be damaged and you will need...

  • Removing Old Andersen 5th Wheel to Gooseneck Coupler For Replacement
  • I spoke to Andersen and this one of their older couplers that they haven't used in years. While they did not have any copies of the instructions it was explained to me that you will need a 3/4" ratchet connection to turn the circle tubing off. You will turn it counter clockwise and it will expose the pieces necessary to remove the coupler assembly. There is a split collar that fits into the slot on the king pin. Above that is a threaded collar that pulls down on the split collars holding...

  • 5th Wheel Trailer is Chucking with Convert-A-Ball 5th Wheel to Gooseneck Adapter
  • Chucking is felt during acceleration and deceleration so if you are feeling it while just driving along then something else is going on which may or may not be related to the Covert-A-Ball adapter # CAB-C5GX1216. If it is the adapter then it could be that the height setting range is not enough to properly work with your truck/trailer set up causing some porpoising which would kind feel like a rocking sensation front to back. There is also a little more play between a gooseneck coupler...

  • Fifth Wheel Trailer Bounce When Towing with a 2002 Chevrolet 2500 HD and Gooseneck Hitch
  • Trailer bouncing and rough rides are common complaints among customers that are towing their fifth wheel trailer with a gooseneck hitch and a gooseneck adapter like part # AM3100. Gooseneck adapters create extra distance between the king pin and trailer hitch and this extra distance creates torque on the trailer frame which creates the chucking and bouncing that you are referring to. Fifth-Wheel-to-Gooseneck coupler adapters are a good solution if you tow a gooseneck trailer and a fifth...

  • Reese Goosebox Loses Air After Sitting for a Few Days
  • There should not be a loss of air pressure with your Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter like part # RP85FR. If this is occurring then that means you have a leak somewhere. In order to find this leak you will want to inflate the system and then spray down the airbag and fittings with soapy water. If you see any bubbles forming then that means there is leak. If you can let me know which part is leaking I can see about getting you replacements (if available).

  • Troubleshooting 5th Wheel Chucking with Andersen Ultimate Gooseneck Hitch
  • The Andersen Ultimate is a nice option for being lightweight, but it is not any help with chucking as you described. It has absolutely no built in assistance for that function. You are pulling a really big trailer, so the chucking will be worse with that than a lightweight 5th wheel because there is simply more momentum so you will feel it more. There really isn't a way to help with the chucking you are experiencing with that particular hitch as air ride will definitely help some but...

  • Troubleshooting Release Cable on Ranch Hitch Adapter
  • Have you measured to make sure the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter # AM3139 works with the hitch ball in your 2016 Nissan Titan XD? If not, what you need to do is line up your fifth wheel and Titan on level ground and measure from the bottom of the pin box to the top of the gooseneck ball. That measurement needs top be between 11-3/4" and 14-3/4" for the adapter to work with your truck. As for the release cable if nothing is happening when you attempt to use...
