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.

How to Maintain Your BULLDOG® Square Tube Jack
The 12,000 lb Square Jack has a maximum rated capacity of 12,000 lb. However, the actual capacity is limited to the lesser of the jack, footplate, or caster wheel capacity. Always refer to the stamped markings or decals on the product to confirm the rated capacity for your specific unit. If you are uncertain, contact Cequent Performance Products at 1-800-521-0510 or www.cequentgroup.com.
The jack has a 2-speed shift pattern where the handle moves 5/8' to 3/4' while shifting. High gear is engaged when the shaft is pushed in, and low gear is engaged when the shaft is pulled out. This clearance must be accounted for during installation to prevent interference with the tow vehicle, tongue, or other accessories.
These jacks are designed for mounting to flat surfaces only. Before mounting, 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 all positions including handle swing in both gears and swivel positions if applicable, and check again after installation is complete.
Before mounting the jack, you must 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 all positions including handle swing (in both gears, if applicable) and swivel positions if applicable. You must check for interference again after installation is complete. If you are unsure about fit, contact Cequent Performance Products at 1-800-521-0510.
All welding must be performed by an AWS certified welder. For direct mount installation, three 2' long 1/4' fillet welds must be placed on both sides of the jack along the contacting surface, positioned as far apart as possible to maximize strength under load. For pivot tube mounting, the non-beveled side of the pivot tube is welded to the tongue with a 1/4' fillet weld all around.
The pivot tube mount includes a supplied pin to secure the jack to the pivot tube after the pivot tube has been welded to the tongue. The pivot pin must be fully inserted through both sides of the pivot tube and the pivot mount before using the jack.
Yes. All welding must be performed by an AWS certified welder. This is a mandatory requirement for both direct mount and pivot tube mounting installations. If you do not have access to an AWS certified welder, you will need to hire a professional welder to complete the installation.
Before mounting the jack, 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 all positions including handle swing (in both gears, if applicable) and swivel positions if applicable. Also verify that the mounting surface is flat, as these jacks are designed for mounting to flat surfaces only.
1) All welding must be performed by an AWS certified welder. 2) Place the jack at the desired location. 3) Weld 3' in 2 locations on both sides of the jack using a 1/4' fillet weld. The three 2' long 1/4' fillet welds should be placed on both sides of the jack along the contacting surface, positioned as far apart as possible to maximize strength under load.
1) All welding must be performed by an AWS certified welder. 2) The non-beveled side of the pivot tube is welded to the tongue. 3) Place the weld-on pivot tube against the tongue and weld all around with a 1/4' fillet weld. 4) Align one set of pivot mount holes vertically. 5) Mate the jack to the pivot tube and secure with the supplied pin.
If mounting jacks in a tandem application, align the jacks carefully so they raise and lower together and share the load equally. This ensures proper load distribution and prevents uneven lifting.
For spring return drop legs: 1) Verify the jack is not supporting any load. 2) If extended, place your foot on the foot plate to control the return. 3) Disengage the drop leg pin by rotating to the disengaged position. 4) Carefully move the drop leg to the desired position using your foot. 5) Engage the drop leg pin by rotating it to the engaged position and into the desired adjustment hole. 6) Verify the drop leg pin is fully inserted by checking for no clearance between the pin and housing. For non-spring return drop legs, grasp the handle of the foot plate to control the fall instead of using your foot.
Never position any part of your body under any portion of this product or the load being supported. Fully retract and/or rotate the jack before towing. When using the drop leg, ensure the drop leg pin is fully inserted before using the jack. Do not allow children to play on or around this product or the load being supported. Secure the load, vehicle and trailer from rolling by blocking wheels when operating the jack or coupling the trailer. Never exceed the maximum rated capacity. These jacks are designed for vertical loading only; excessive side forces may cause jack failure and must be avoided. Do not adjust the drop leg when the jack is under load. Keep clear of pinch points at the drop leg pin and holes in the drop leg.
Fully retract and/or rotate the jack before towing. This prevents interference with the road and ensures safe towing.
No. Never attempt to adjust the drop leg when the jack is under load. Always verify that the jack is not supporting any load before adjusting the drop leg.
Secure the load, vehicle and trailer from rolling by blocking the wheels when operating the jack or coupling the trailer. This prevents the vehicle or trailer from moving unexpectedly while the jack is in use.
Keep clear of the pinch point at the drop leg pin. The drop leg will naturally drop or retract very quickly depending on the model, which can cause pinching or crushing injuries. Also keep clear of holes in the drop leg.
These jacks are designed for vertical loading only. Excessive side forces may cause jack failure and must be avoided. Applying side forces to the jack can compromise its structural integrity and create a safety hazard.
After installation is complete, check for interference again in all positions including handle swing (in both gears, if applicable) and swivel positions if applicable. Verify that the drop leg pin is fully inserted into the jack by checking for no clearance between the drop leg pin and housing. If you see clearance, you must adjust the drop leg to fully seat the pin into the hole location.
Check for no clearance between the drop leg pin and housing. If you see clearance, you must adjust the drop leg to fully seat the pin into the hole location. You may need to lubricate the drop leg pin assembly as described in the maintenance section. If you are unable to fully seat the pin, do not use the jack.
The following procedures should be performed at least annually: The gears, bushings, and screw of the jack must be kept lubricated. For side-wind models, apply a small amount of automotive grease with a grease gun at the lubrication points found on the side of the jack near the input shaft. Rotate the jack handle to distribute the grease evenly. A lightweight oil must be applied to the input shaft bushings at both sides of the jack or gearbox. For top-wind models, the screw-stem should be lubricated with a lightweight oil. If equipped, the drop leg pin and spring must be kept clean and lubricated with a lightweight oil.
Use automotive grease with a grease gun at the lubrication points on side-wind models. Use lightweight oil for the input shaft bushings at both sides of the jack or gearbox, and for the screw-stem on top-wind models. If equipped, the drop leg pin and spring must be kept clean and lubricated with lightweight oil.
For side-wind models, the lubrication points are found on the side of the jack near the input shaft. Apply a small amount of automotive grease with a grease gun at these points and rotate the jack handle to distribute the grease evenly.
