Founded in 1920, Bulldog has become the standard for heavy-duty trailer connection hardware in agricultural, military and utility service. The line covers gooseneck hitches and couplers, A-frame and channel-mount trailer couplers with the Wedge-Latch mechanism, and heavy-duty jacks, built for unmatched strength, reliability and safety under demanding loads.
Bulldog was founded in 1920 and has spent more than a century supplying the connection hardware that heavy trailers depend on. Its market has always been the demanding end: agricultural, military and utility applications where a coupler failure is not an inconvenience but a serious incident. The brand summarises its position as Tough and Tested, and it sits within the Horizon Global towing group alongside Reese, Draw-Tite, Fulton, Tekonsha, Bargman and Wesbar.
Gooseneck equipment is the brand's signature. Gooseneck hitches mount in the truck bed over the rear axle, which places the load where the chassis can carry it properly and allows far tighter turning than a receiver hitch permits. Matching gooseneck couplers attach at the trailer end, in round tube and square configurations across the capacity range used by livestock, equipment and flatbed trailers.
The conventional trailer coupler range is built around the Wedge-Latch mechanism, which uses a wedge to take up wear between coupler and ball rather than relying on a fixed clamp that loosens over time. That matters on a trailer accumulating hard miles, where slack in the coupling shows up as noise and shock loading. Couplers are offered in A-frame form for standard tongues and in channel-mount form for straight tongue and fabricated frames, with adjustable channel versions that let a coupler be positioned to suit the tongue height.
Heavy-duty jacks complete the line, sized for the tongue weights that gooseneck and equipment trailers generate. Across the range the emphasis is consistent: forged and heavy-section components, load ratings backed by testing, and hardware specified for agricultural, military and heavy-duty commercial use rather than occasional recreational towing.

Use only a 2 5/16" ball rated equal to or greater than the capacity of the coupler. If uncertain, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.
The coupler is available in four capacity ratings: 20K Round, 25K Round, 25K Square, and 30K Round.
Yes. All welding must be performed by an AWS certified welder. This is a mandatory requirement for proper installation and load support.
All hardware must be torqued to 125 ft. lbs. minimum. Periodically check for proper torque and tighten if necessary.
Do not exceed 8" maximum extension. Measure the coupler extension as the difference between fully retracted and fully extended positions. Couplers with properly installed load bearing pins and square adjustable gooseneck couplers only extend within this range.
No. Do not tow unless the load bearing pin is fully inserted through both the inner and outer tubes and the retaining pin is installed. The coupler cannot support its rated load without these components properly installed.
Yes. Always secure the load, vehicle and trailer by blocking wheels before latching or unlatching the coupler.
The Bulldog Gooseneck Coupler is a trailer coupling device manufactured by Cequent Performance Products. It connects a gooseneck trailer to a towing vehicle via a 2 5/16" hitch ball. The coupler is available in four capacity ratings: 20K Round, 25K Round, 25K Square, and 30K Round. It is rated according to SAE J2638 standard.
SAE J2638 is the standard to which the coupler is rated. This standard establishes the specifications and performance requirements for gooseneck couplers.
No. Use only a 2 5/16" ball rated equal to or greater than the capacity of the coupler. Using a different size will not fit properly and will compromise safety. If you are uncertain about the correct ball size or rating, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.
Do not exceed the lesser of the coupler, hitch, vehicle, ball, or trailer weight ratings, including the load. Weigh your trailer plus added load before towing. Exceeding any of these ratings can result in failure and serious injury or death.
Before mounting the coupler, confirm that there will be no interference from the tow vehicle, tongue, ground, and any other mounted accessories while stationary or in motion. Check for interference in both extended and retracted positions before installation. Check for interference again after installation is complete. The coupler must remain vertical after installation to ensure proper operation.
The set bolts must be facing the towing vehicle. This orientation is required for proper installation and operation.
No. The purchaser/owner must not alter or modify the product. Modifications will void the warranty and may compromise safety and load capacity.
Avoid heat damage to the coupler during welding. Do not weld over or near any holes or hardware on the coupler. All welding must be performed by an AWS certified welder. The outer tube must be rigidly attached to the trailer to support the maximum rated load according to SAE J2638.
The outer tube must be supported completely by attaching gussets as low as possible to the outer tube. For adjustable couplers, reinforcements must extend down the outer tube to within 3" above the bottom of the outer tube. For non-adjustable couplers, reinforcement must be within 20 inches above the locking plates. To reduce stress concentrations in high load, high mileage, or rough service applications, gussets and banding that tie trailer framing to the coupler are required. Gusset specifications are dependent on trailer design and customer requirements, and this modification is the responsibility of the trailer manufacturer.
1) Block trailer wheels. 2) Align hitch ball beneath coupler. 3) Set the locking pin in the open position. 4) Slide the locking plate into the open position and lower the trailer onto the hitch ball. 5) Visually check that the hitch ball is fully seated in the coupler. 6) Slide the locking plate into the closed position. 7) Set the locking pin in the closed position to close the coupler.
1) Block trailer wheels. 2) Set the locking pin in the open position. 3) Slide the locking plate into the open position and raise the trailer from the hitch ball.
Yes. Visually check that the hitch ball is fully seated in the coupler ball pocket and the latch is closed before towing. Ensure that the coupler opens, closes, and the handle springs closed when released.
The operator and bystanders should never position any body part under any portion of the coupler or the load being supported. Do not allow children to play on or around the coupler or the load being supported.
Before towing: 1) Check vehicle, hitch ball and coupler for signs of wear or damage. 2) Ensure that the coupler opens, closes, and the handle springs closed when released. 3) Replace bent, broken, or worn parts before using. 4) Ensure that the hitch ball is fully seated in the coupler ball pocket and the latch is closed. 5) Make sure that the trailer safety chains are properly connected to the towing vehicle and trailer. 6) Make sure that all trailer lighting is hooked up and working properly.
The following procedures should be performed at least annually: 1) Check hardware torque. 2) Grease ball pocket. 3) Oil pivot points with SAE 30 wt. motor oil. 4) Inspect retaining pin and replace if necessary. Keep the ball pocket, latch, and handle clean.
Periodically check for proper torque and tighten if necessary. All hardware must be torqued to 125 ft. lbs. minimum. Check for wear on the inner tube if retightening is needed. A formal torque check should be performed at least annually as part of routine maintenance.
Oil pivot points with SAE 30 wt. motor oil. This should be done at least annually as part of routine maintenance.
Grease the ball pocket. This should be done at least annually as part of routine maintenance.
Inspect the retaining pin at least annually and replace if necessary. The retaining pin should be replaced if it shows signs of wear or damage.
After installation, check to make sure that coupler operation has not been impaired in any way. Do not use the coupler if its operation has been impaired. After assembly and painting, but prior to being used, any enclosed labels must be affixed to the coupler and premask removed. Check for interference again after installation is complete to ensure no interference from the tow vehicle, tongue, ground, or other mounted accessories.

The load bearing pin is a component that must be fully inserted through both the inner and outer tubes in order for the coupler to support its rated load. If equipped with a load bearing pin, it must be fully inserted and the retaining pin must be installed. Do not tow unless the load bearing pin is fully inserted and the retaining pin is installed.
The load bearing pin is inserted through both the inner and outer tubes to support the rated load. The retaining pin (also called the locking nut on some models) is installed to secure the load bearing pin in place. Both must be properly installed for the coupler to support its rated load and for safe towing.
Yes. The coupler must remain vertical after installation to ensure proper operation. If the coupler is not vertical, it may not operate correctly and could fail during use.
Do not use the coupler if its operation has been impaired in any way. After installation, check to make sure that coupler operation has not been impaired. If you discover any impairment, contact Cequent Performance Products at 1-800-632-3290 before using the coupler.
After assembly and painting, but prior to being used, any enclosed labels must be affixed to the coupler and premask removed. These labels include warning labels, caution labels, and capacity labels that are important for safe operation.
Yes. Make sure that the trailer safety chains are properly connected to the towing vehicle and trailer before towing. This is a critical safety requirement.
Yes. Make sure that all trailer lighting is hooked up and working properly before towing.
This indicates a problem with the coupler mechanism. Before towing, ensure that the coupler opens, closes, and the handle springs closed when released. If the handle does not spring closed, replace the coupler or have it serviced by a qualified technician before using it. Do not tow with a coupler that is not functioning properly.
Replace bent, broken, or worn parts before using the coupler. Check the vehicle, hitch ball, and coupler for signs of wear or damage before towing. If damage is found, do not use the coupler until the damaged parts have been replaced. Contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
Before mounting the coupler, confirm that there will be no interference from the tow vehicle, tongue, ground, and any other mounted accessories while stationary or in motion. Check for interference in both extended and retracted positions before installation. Check for interference again after installation is complete. If interference is found, adjust the coupler position, height, or orientation, or modify the trailer design to eliminate the interference. Do not use the coupler if interference exists.
Visually check that the hitch ball is fully seated in the coupler ball pocket before towing. If the ball is not fully seated, raise the trailer and reposition it so that the ball is properly seated. Ensure that the latch is closed. Do not tow if the ball is not fully seated, as this could result in the trailer becoming detached.
