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.

The coupler requires a 2 5/16" hitch ball rated equal to or greater than the coupler's capacity. If uncertain about the correct rating, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.
The coupler is available in four models: 20K Round, 25K Round, 25K Square, and 30K Round. Each model has a specific weight capacity rating that must not be exceeded, including the load.
Yes. The product is rated according to SAE J2638, which is the industry standard for gooseneck couplers.
Yes. All welding must be performed by an AWS (American Welding Society) certified welder. This is a mandatory requirement stated in the installation instructions.
The maximum extension is 8 inches, measured as the difference between the fully retracted and fully extended positions. Do not exceed this limit. Couplers with properly installed load bearing pins and square adjustable gooseneck couplers only extend within this range.
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.
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. If equipped with a load bearing pin, it must be fully inserted through both the inner and outer tubes in order for the coupler to support its rated load. Do not tow unless the load bearing pin is fully inserted and the retaining pin is installed.
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. 4) Ensure the hitch ball is fully seated in the coupler ball pocket and the latch is closed. 5) Verify trailer safety chains are properly connected to the towing vehicle and trailer. 6) Verify 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.
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.
Yes. 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 inches 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 and banding specifications are the responsibility of the trailer manufacturer.
The set bolts must be facing the towing vehicle. This orientation is required before installation begins.
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 in order for the coupler to support its maximum rated load according to SAE J2638.
After assembly and painting, but prior to being used, any enclosed labels must be affixed to the coupler and premask removed.
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 to ensure you do not exceed any of these ratings.
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 the load, vehicle, and trailer (by blocking wheels) before latching or unlatching the coupler.
No. The purchaser/owner must not alter or modify the product. The coupler must be installed according to the manufacturer's instructions and must not be modified in any way.
Maintenance procedures should be performed at least annually. These include checking hardware torque, greasing the ball pocket, oiling pivot points with SAE 30 wt. motor oil, and inspecting the retaining pin for wear or damage.

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 issues with opening, closing, or the handle springing closed, do not tow until the problem is resolved.
Yes. The coupler must remain vertical after installation to ensure proper operation. 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.
Oil pivot points with SAE 30 wt. motor oil. This should be done at least annually as part of regular maintenance.
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. The set bolts must be facing the towing vehicle. Verify that the coupler will reach the towing vehicle to couple with the hitch ball.
The trailer manufacturer is responsible for providing gusseting and banding specifications and installation. 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. These modifications must be designed and installed by the trailer manufacturer according to the coupler's specifications.
