I replaced the existing coupler on my 20' 14,0000# GVW flatbed trailer with this coupler. What a difference! I think it would be conservative to say that making this change has cut the jarring from the trailer to the tow vehicle easily in half. After buying the first one of these for my own use I ordered a second one for a conversion to a customer's trailer. What a simple fix for a very annoying problem! 31269

  • Does Gooseneck Trailer Lock # 2989AT Fit Convert-A-Ball Gooseneck Trailer Coupler # CG
  • I went out to the warehouse and pulled a Convert-A-Ball Multi-Cushioned Gooseneck Trailer Coupler, # CG, and a Gooseneck Trailer Lock, # 2989AT. The lock does fit on Gooseneck Coupler, # CG. If you look at the bottom of the CG coupler, you will notice that it has a rectangular part. The lock fits on lengthwise or widthwise depending on how you might need to attach the lock. I have included a video review of this lock below.

  • Is Chucking and Noise Normal When Towing a Gooseneck Trailer
  • What you are describing sounds like chucking. The trailer coupler on your gooseneck trailer has to be able to rotate around the ball. Because of this there is some space allowing it to move freely around the ball when you turn. This also leaves space for the noise and movement you are describing; known as chucking. It is normal unless it is very excessive. If it is slight and only happens during acceleration and braking events, then it is normal behavior. There is also the chance, though...

  • Does The Convert-A-Ball Multi-Cushioned Gooseneck Trailer Coupler # CG Allow For Height Adjustment
  • The Convert-A-Ball Multi-Cushioned Gooseneck Trailer Coupler, part # CG, will slide up in the 4 inch inner diameter tube that is on the trailer. It can be adjusted for height by using the set screws on the gooseneck trailer tube. If your gooseneck needs the coupler with the holes along the tube, for installing the safety pin, you will need the Convert-A-Ball Multi-Cushioned Gooseneck Trailer Coupler, part # CGH. This is the same coupler as the part # CG, but it has holes that are drilled...

  • Can Convert-A-Ball Trailer Coupler, # CG, Be Welded To The Trailer
  • I called the supplier (Convert-A-Ball) and they said the Convert-A-Ball Trailer Coupler, # CG, can be welded, but recommended it be welded by a experienced welding shop. They also mentioned it would have to be welded at least 12 inches up from the bottom and cooled immediately because there is polyurethane cushions on the inside of the coupler which could be affected by the heat buildup when welding.

  • Gooseneck to 5th Wheel Adapter # 16085 Recommendation
  • This Convert-A-Ball Multi-Cushioned Gooseneck Trailer Coupler, part # CG, is a cushioned coupler for a gooseneck trailer. Convert-A-Ball is the brand name, this will not allow you to pull your trailer with a fifth wheel hitch. If you have a fifth wheel hitch in your truck and you are needing to pull a gooseneck trailer I would recommend you get a Curt Spyder Gooseneck Trailer Hitch for Fifth Wheel Rails, part # 16085. This product will mount into Valley, Draw-Tite, Reese, Hidden Hitch...

  • Pin Weight Capacity of Convert-A-Ball Cushioned Gooseneck Coupler # CG
  • I spoke with my contact at Convert-A-Ball about the pin weight capacity of their CG Cushioned Gooseneck Coupler. They list a 30,000 lb weight capacity for the coupler, but no tongue or pin weight capacity is listed. Since your 2400 lb pin weight isn't even 10 percent of the 30K coupler capacity, the coupler should handle it just fine.

  • What Is Needed For More Clearance Between The Bed Rails And Gooseneck Trailer On A Ford F-150 Truck
  • A good rule to follow is to allow 6 inches or more of clearance between the sides of the bed and the bottom of the gooseneck trailer to allow for dips and bumps in the road. You will want to check your gooseneck coupler to see if it has an adjustable tube with set screws that will allow you to adjust the height of the coupler for extra clearance when attached to your vehicle. If it does then you can loosen the set screws and adjust the length of the tube to get more clearance. If...
