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.
All hardware must be torqued to 125 ft. lbs. minimum. Periodically check for proper torque and tighten if necessary. Check for wear on inner tube if retightening is needed.
Yes. All welding must be performed by an AWS certified welder. Avoid heat damage to the coupler during welding and do not weld over or near any holes or hardware on the coupler.
Do not exceed 8" maximum extension. Measure 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 the load bearing pin fully inserted.
Perform these procedures at least annually: check hardware torque, grease ball pocket, oil pivot points with SAE 30 wt. motor oil, and inspect retaining pin and replace if necessary. Keep the ball pocket, latch, and handle clean.
The Bulldog Gooseneck Coupler is a trailer coupling device that connects a gooseneck trailer to a towing vehicle via a 2 5/16" hitch ball. It is available in four capacity ratings: 20K Round, 25K Round, 25K Square, and 30K Round. The coupler features a load bearing pin that must be fully inserted for rated load capacity, locking plates for securing the connection, and an adjustable design (on some models) that extends up to 8" to accommodate different hitch heights.
The Bulldog Gooseneck Coupler is available in four capacity ratings: 20K Round, 25K Round, 25K Square, and 30K Round. Each model is labeled with its capacity on the coupler itself.
The Bulldog Gooseneck Coupler is designed for gooseneck trailers equipped with a 2 5/16" hitch ball. Before installation, 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 (for adjustable models) before and after installation. The coupler must be mounted vertically and rigidly attached to the trailer frame via gusseting to support its rated load.
Do not exceed the lesser of the coupler, hitch, vehicle, ball, or trailer weight ratings (including load). Weigh your trailer plus added load before towing. The specific weight capacity depends on which model you have (20K, 25K, or 30K). Refer to the capacity label on your coupler or contact Cequent Performance Products at 1-800-632-3290 if you are uncertain about your coupler's rating.
The manual does not specify the tools required for installation. However, because all welding must be performed by an AWS certified welder and the coupler must be rigidly attached to the trailer frame with gusseting, you will need welding equipment and an AWS certified welder. For specific tool requirements, contact Cequent Performance Products at 1-800-632-3290.
The manual does not mention battery disconnection. Since this is a mechanical coupler with no electrical components, battery disconnection is not required.
The manual does not specify whether drilling is required. Installation involves welding the coupler to the trailer frame with gusseting for reinforcement. For specific information about drilling or other modifications needed for your trailer, contact Cequent Performance Products at 1-800-632-3290 or consult with an AWS certified welder.
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 size and welding specifications depend on trailer design and customer requirements. This modification is the responsibility of the trailer manufacturer. Consult with an AWS certified welder for your specific application.
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.
Before towing, perform these checks: 1) Check vehicle, hitch ball, and coupler for signs of wear or damage. 2) Ensure the coupler opens, closes, and the handle springs closed when released. 3) Replace bent, broken, or worn parts before using the product. 4) Ensure the hitch ball is fully seated in the coupler ball pocket and the latch is closed. 5) Make sure trailer safety chains are properly connected to the towing vehicle and trailer. 6) Make sure all trailer lighting is hooked up and working properly. Additionally, always secure load, vehicle, and trailer by blocking wheels before latching or unlatching the coupler.
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. Always secure load, vehicle, and trailer by blocking wheels before latching or unlatching the coupler.
After installation is complete, check for interference again in both extended and retracted positions (for adjustable models). Verify that the coupler remains vertical after installation to ensure proper operation. After assembly and painting, but prior to being used, any enclosed labels must be affixed to the coupler and premask removed. 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.
Periodically check for proper torque and tighten if necessary. The manual recommends performing a hardware torque check at least annually as part of routine maintenance. Check for wear on the inner tube if retightening is needed.
Grease the ball pocket at least annually. Oil pivot points with SAE 30 wt. motor oil at least annually. Keep the ball pocket, latch, and handle clean.
Inspect the retaining pin at least annually and replace if necessary. The retaining pin must be fully installed through the load bearing pin hole to ensure the coupler can support its rated load.
No. The purchaser/owner must not alter or modify the product. The coupler must be installed according to the manufacturer's instructions and remain in its original condition to maintain its rated load capacity and safety.

The manual indicates that square adjustable gooseneck couplers extend within the 8" maximum extension range, while non-adjustable couplers do not extend. The gusseting requirements differ: adjustable couplers require reinforcements to within 3" above the bottom of the outer tube, while non-adjustable couplers require reinforcements within 20 inches above the locking plates. Both types must have a load bearing pin fully inserted through both inner and outer tubes to support their rated load.
The load bearing pin is a component that must be fully inserted through both the inner and outer tubes of the coupler 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 coupler cannot support its maximum rated load according to SAE J2638 without the load bearing pin properly installed.
The set bolts must be facing the towing vehicle. The coupler must remain vertical after installation to ensure proper operation.
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. Before installing, check for interference in extended and retracted positions (for adjustable models). Check for interference again after installation is complete. If interference is found, do not use the coupler until the issue is resolved.
All welding must be performed by an AWS certified welder. Avoid heat damage to the coupler during welding. Do not weld over or near any holes or hardware on the coupler. The outer tube must be rigidly attached to the trailer in order for the coupler to support its maximum rated load according to SAE J2638.
This indicates the coupler may be damaged or worn. Before towing, check the coupler for signs of wear or damage. Ensure that the coupler opens, closes, and the handle springs closed when released. Replace bent, broken, or worn parts before using the product. Do not use the coupler if its operation has been impaired.
Ensure that the hitch ball is fully seated in the coupler ball pocket and the latch is closed. If the ball does not seat fully, check that: 1) The hitch ball is the correct size (2 5/16"). 2) The ball pocket is clean. 3) The coupler is not damaged. If the ball still does not seat, do not tow. Replace any bent, broken, or worn parts before using the product.
Excessive vibration indicates the coupler may not be properly secured. Tighten the set bolt(s) and nut(s) to minimize vibrations in the coupler during towing. All hardware must be torqued to 125 ft. lbs. minimum. Periodically check for proper torque and tighten if necessary. Check for wear on the inner tube if retightening is needed. If vibration persists after retorquing, inspect the coupler for damage and contact Cequent Performance Products at 1-800-632-3290.
No. 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 notice any problems with opening, closing, locking, or the handle function, do not tow. Replace bent, broken, or worn parts before using the product. Contact Cequent Performance Products at 1-800-632-3290 for repair or replacement options.
Keep the ball pocket, latch, and handle clean. The manual does not specify a cleaning method. Clean the ball pocket regularly to ensure proper seating of the hitch ball. If corrosion is present, contact Cequent Performance Products at 1-800-632-3290 for guidance on cleaning or replacement.
