  • Recommended Heavy Duty Gooseneck Coupler For Clearance and Adjustability
    It sounds like you want vertical adjustability for 30K gooseneck coupler. It appears you may be seeking 30 inches of vertical travel and we don't have anything with that capacity. The normal range is 7-8 inches but the retracted heights can vary. We have the following options for you: Bulldog Gooseneck Coupler- Round - 30,000 lbs # BD0289500300 with 8 inches vertical travel with a retracted height of 29-1/3 inches.

  • 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...

  • Troubleshooting Gooseneck Hitch that Won't Lock onto 2-5/16 inch Ball
    It really sounds like your gooseneck hitch is designed for a 3 inch gooseneck ball. I know you said that you attached to your friends B and W hitch, but B and W offers a 3 inch ball # BWGNXA2025. The 3 inch setup is less common but it is still seen out there. If your trailer is larger it is very possible that you need a 3 inch ball. Which there are no adapters like the Spyder that have 3 inch balls. This would call for the replacement of your coupler or the install of a gooseneck hitch...

  • Will a Blaylock EZ Lock for Set Screws on Gooseneck Couplers Fit a Square Bulldog Trailer Coupler
    The Blaylock EZ Lock, # BLTL-51, should work fine with a square Bulldog gooseneck coupler like # BD0289800300, # BD0289600300, or # BD028900. Provided the coupler that you have uses set screws to hold the inner tube in place, this lock will prevent anyone from tampering with the set screws to release the inner tube. You could use # BLTL-53-40D2. This comes with the set screw lock, the coupler lock for the bottom of the coupler, and 2 padlocks.
