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.

A tongue jack is a device mounted on a trailer tongue that raises and lowers the front of the trailer for coupling, uncoupling, and ground clearance. The manual covers multiple mounting styles (bolt-on, snap ring, bolt-thru, direct-mount weld-on, A-plate, and pivot tube) and handle types (side-wind and top-wind), with optional accessories including drop foot, drop leg, and caster wheels.
No. The manual explicitly states: "These jacks are not designed for mounting to round tongues." They are designed for flat or rectangular tongues only.
Yes, if you have an A-plate jack. A-plate jacks are specifically designed for mounting to trailers with A-plate couplers. The manual recommends attaching a bottom support plate to the bottom of the tongue for additional strength.
Before mounting, confirm there will be no interference from the tow vehicle, tongue, ground, or any other mounted accessories while stationary or in motion. Check for interference in all positions, including handle swing and swivel positions if applicable. Check again after installation is complete.
Secure all mounting bolts with locknuts and torque to 25 ft. lbs. (3.5 m/kg).
The gap between the mounting bolts and the tongue is not to exceed 1/16 inch (1.5 mm). The upper bolts should rest on the top of the tongue, and the lower bolts should be less than 1/16 inch from the bottom of the tongue.
1) Place the jack bracket over the mount. 2) Place the snap ring in the groove. 3) Seat the snap ring fully into the groove. Before installing, inspect the snap ring groove and remove any debris.
1) Place the jack bracket into the recessed opening on the mount. 2) Place the small end of the bushing into the jack bracket and onto the bolt. 3) Tighten the locknut until there is little movement in the bushing. The bolt should be installed between the trailer tongue and mount; the jack bracket will be held by the bushing between the locknut and the mount.
The manual does not specify whether drilling is required. It assumes mounting holes already exist on the tongue and instructs you to align the mounting bracket holes with existing holes in the mounting straps. Consult the manufacturer or your trailer documentation to confirm whether pre-drilled holes are present.
All welding must be performed by an AWS certified welder. Place the jack at the desired location and weld 1 inch in 2 locations on both sides of the jack using a 3/16 inch fillet weld.
All welding must be performed by an AWS certified welder. If the A-plate is separate from the jack, align the jack (and foot, if equipped) with the jack and coupler before welding using a 3/16 inch fillet weld. Bolt the jack A-plate to the coupler using three 3/8-16 grade 5 bolts with washers, torqued to 15-20 ft. lbs. (2-2.7 m/kg). Weld the recommended support plate to the bottom of the trailer frame using a 3/16 inch fillet weld. If the jack is a plain mount type, it may be mounted directly to a coupler with a 3/16 inch fillet weld.
All welding must be performed by an AWS certified welder. The non-beveled side of the pivot tube is welded to the tongue unless otherwise specified. Place the weld-on pivot tube against the tongue and weld all around with a 3/16 inch fillet weld. Align one set of pivot mount holes vertically. Then mate the jack to the pivot tube and secure with the supplied pin.
No. The manual explicitly states: "Do not attempt to weld 'Bolt-On' brackets or straps to the tongue. Special brackets are available for 'Weld-On' applications." If you need a weld-on installation, contact the manufacturer for the appropriate brackets.
Fully retract and rotate the jack before towing. If using an optional drop foot or caster, always remove it before towing to maximize ground clearance.
Jack capacity is limited to the lesser of the jack, footplate, or caster wheel capacity. Never exceed the maximum rated capacity. Refer to the stamped markings or decals on the product to obtain the rated capacity. If uncertain, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.
No. These jacks are designed for vertical loading only. Excessive side forces may cause jack failure and must be avoided.
Crank the jack to its lowest position before manually moving the trailer.
If the product is a swivel jack, lock the plunger pin into a hole in the mounting bracket before raising or lowering the tongue.
If the product has a pivot tube mount, make certain the pivot pin is fully inserted through both sides of the pivot tube and the pivot mount before using the jack.
When using the drop foot or drop leg, make certain the supplied pin is fully inserted through both sides of the inner tube and the drop tube before using the jack. Never attempt to adjust the drop foot or drop leg when there is any load on the jack.
No. If the product is a rack jack, do not raise the gear housing above the inner tube.
Operator and bystanders should never position any part of their body under any portion of the jack or the load being supported.
Yes. Secure the load, vehicle, and trailer from rolling by blocking the wheels when operating the jack or coupling the trailer.
No. Do not allow children to play on or around the jack or the load being supported.
The following procedures should be performed at least annually: For side-wind models, apply a small amount of automotive grease to the internal gearing by removing the jack cover or using a needle nose applicator or standard grease gun on the lubrication point found on the side of the jack near the crank. Rotate the jack handle to distribute the grease evenly. Apply a lightweight oil to the handle unit at both sides of the tube for side-wind models. If equipped, lubricate the axle bolt and nut assembly of the caster wheel with the same lightweight oil. For top-wind models, apply a lightweight oil to the screw stem. If the product is used in a marine environment, flush the jack assembly and bushings with fresh water and apply fresh lubricant.
Use automotive grease for internal gearing and bushings on side-wind models. Use lightweight oil for the handle unit on side-wind models, the axle bolt and nut assembly of caster wheels, and the screw stem on top-wind models. If the product is used in a marine environment, flush with fresh water and apply fresh lubricant.
The manual does not specify required tools. For bolt-on installations, you will need a wrench or socket to torque bolts to 25 ft. lbs. For welded installations, an AWS certified welder is required. For assembly of optional accessories (caster wheels, handles), you will need a wrench to secure bolts and nuts.
The manual states that supplied bolts are included for mounting, and locknuts are used to secure them. For snap ring models, a snap ring is included. For bolt-thru models, a bushing and locknut are included. The exact quantity and specifications of all included fasteners are not detailed in the manual.
Three 3/8-16 grade 5 bolts with washers are required to bolt the jack A-plate to the coupler. These are torqued to 15-20 ft. lbs. (2-2.7 m/kg). The manual does not specify whether these bolts are included or must be purchased separately.
To attach a wheel assembly, a long spacer, bolt, and nut are provided. For a heavy duty caster, four 3/8 inch bolts, washers, and locknuts are required.
For side-wind models, a long spacer, thin spacer, bolt, and nut are provided. For top-wind models, a washer, bolt, and nut are provided.
The manual does not specify whether professional installation is required or recommended. For welded installations, an AWS certified welder is mandatory. For bolt-on installations, the manual provides step-by-step instructions but does not indicate the skill level required. Contact the manufacturer or an authorized installer if you are unsure.
After installation is complete, check for interference again in all positions, including handle swing and swivel positions if applicable. For bolt-on installations, verify clearance of the handle, trailer light cables, and coupler.
No. The purchaser/owner must not alter or modify the product. Any modifications not specified in the installation instructions and performed in a workmanlike manner may void the warranty and create safety hazards.
Always replace bent, broken, or worn parts before using the product. Use only Cequent Performance Products' parts or parts of equal quality for repair. Replacement parts are available through Cequent Performance Products' Customer Service Department at 1-800-632-3290. Please specify the product model number.
Tongue jacks are available in multiple mounting styles (bolt-on, snap ring, bolt-thru, direct-mount weld-on, A-plate, and pivot tube). They are not designed for round tongues. Confirm your tongue type and coupler style (A-plate or standard) with your trailer documentation, then select the appropriate jack model. Contact Cequent Performance Products at 1-800-632-3290 if you are unsure.
For bolt-on models, the manual assumes mounting holes already exist on the tongue. For welded models (direct-mount, A-plate, pivot tube), no drilling is required, but AWS certified welding is mandatory. Consult your trailer documentation to confirm whether pre-drilled holes are present.
Bolt-on models: 25 ft. lbs. (3.5 m/kg). A-plate models: 15-20 ft. lbs. (2-2.7 m/kg) for the three 3/8-16 grade 5 bolts connecting the A-plate to the coupler.
Fully retract and rotate the jack before towing. If using an optional drop foot or caster, remove it before towing to maximize ground clearance.
At least annually. Side-wind models require automotive grease on internal gearing and lightweight oil on the handle. Top-wind models require lightweight oil on the screw stem. If used in a marine environment, flush with fresh water and apply fresh lubricant.
Yes, if you are installing a weld-on model (direct-mount, A-plate, or pivot tube). All welding must be performed by an AWS certified welder. Bolt-on models do not require welding.
Before installing the snap ring, inspect the snap ring groove and remove any debris. Seat the snap ring fully into the groove. If the snap ring still does not seat properly after cleaning, the groove may be damaged. Replace the jack or contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
Tighten the locknut until there is little movement in the bushing. Do not over-tighten, as this may damage the bushing. If movement persists after tightening, the bushing may be worn and require replacement. Contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
For side-wind models, the internal gearing and bushings may need lubrication. Apply a small amount of automotive grease to the internal gearing by removing the jack cover or using a needle nose applicator or standard grease gun on the lubrication point found on the side of the jack near the crank. Rotate the jack handle to distribute the grease evenly. For top-wind models, apply lightweight oil to the screw stem. If the problem persists, contact Cequent Performance Products at 1-800-632-3290.
Noise may indicate that the jack needs lubrication. For side-wind models, apply a small amount of automotive grease to the internal gearing and lightweight oil to the handle unit at both sides of the tube. For top-wind models, apply lightweight oil to the screw stem. Rotate the jack handle to distribute lubricant evenly. If noise persists, contact Cequent Performance Products at 1-800-632-3290.
If the product is used in a marine environment, flush the jack assembly and bushings with fresh water and apply fresh lubricant at least annually. For general corrosion, clean the affected areas and apply a protective coating. If corrosion is severe, contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
Tighten all mounting bolts to the specified torque: 25 ft. lbs. (3.5 m/kg) for bolt-on models, or 15-20 ft. lbs. (2-2.7 m/kg) for A-plate models. Use a torque wrench to ensure proper tightness. Check bolts periodically, as vibration during towing may cause them to loosen over time.
After installation, verify clearance of the handle, trailer light cables, and coupler. If interference is present, the jack may not be positioned correctly. Loosen the mounting bolts, reposition the jack to eliminate interference, and re-tighten to the specified torque. If repositioning is not possible, contact Cequent Performance Products at 1-800-632-3290 for alternative mounting options.
Make certain the pivot pin is fully inserted through both sides of the pivot tube and the pivot mount. If the pin continues to slip out, it may be bent or worn. Replace the pivot pin with a new one. Contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
If the product is a swivel jack, lock the plunger pin into a hole in the mounting bracket before raising or lowering the tongue. If the pin does not lock securely, it may be bent or the mounting bracket holes may be damaged. Replace the pin or contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
When using the drop foot or drop leg, make certain the supplied pin is fully inserted through both sides of the inner tube and the drop tube before using the jack. If the pin continues to slip out, it may be bent or worn. Replace the pin with a new one. Contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
