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 mechanical device mounted to a trailer tongue that raises and lowers the front of the trailer for coupling, uncoupling, and ground clearance. The manual covers multiple styles: bolt-on rack jacks, snap ring models, bolt-thru models, direct-mount weld-on jacks, A-plate jacks, and weld-on pivot tube jacks. They are available with side-wind or top-wind handle operation and optional drop foot, drop leg, or caster wheel accessories.
No. The manual explicitly states: 'These jacks are not designed for mounting to round tongues.' Tongue jacks are designed for flat or rectangular tongues only.
The gap between the mounting bolts and the tongue must not exceed 1/16 inch (1.5 mm). This applies to bolt-on mounting brackets. 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.
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 and swivel positions if applicable. Check for interference again after installation is complete. Also verify clearance of the handle, trailer light cables, and coupler.
Secure all mounting bolts with locknuts and torque to 25 ft. lbs. This applies to both rack jack mounting and bolt-on mounting bracket installations.
To attach a snap ring model jack: 1) Place the jack bracket over the mount and place the snap ring in the groove. 2) Seat the snap ring fully into the groove. Before installing the snap ring, inspect the snap ring groove and remove any debris to ensure proper seating.
To attach a bolt-thru model jack: 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. Note: 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.
No. Do not attempt to weld bolt-on brackets or straps to the tongue. Bolt-on jacks are secured with bolts and locknuts only. If you need a welded installation, special weld-on brackets are available for that application.
All welding must be performed by an AWS certified welder. For direct-mount jacks, weld 1 inch in 2 locations on both sides of the jack using a 3/16 inch fillet weld. For A-plate jacks, use a 3/16 inch fillet weld. For weld-on pivot tube mounts, weld all around the pivot tube with a 3/16 inch fillet weld. A bottom support plate is recommended for A-plate installations and should also be welded with a 3/16 inch fillet weld.
When bolting the jack A-plate to the coupler, use three 3/8-16 grade 5 bolts with washers and torque to 15-20 ft. lbs.
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. Before manually moving the trailer, crank the jack to the lowest position.
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.
Never position any part of your body under any portion of the jack or the load being supported. Secure the load, vehicle, and trailer from rolling by blocking the wheels when operating the jack or coupling the trailer. Do not allow children to play on or around the jack or the load being supported. Do not use the jack as a transport device for the implement it is attached to; minimize movement of the implement while the jack is under load.
A drop foot or drop leg is an optional accessory that extends downward from the jack to provide additional ground support. When using a 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. Always remove the drop foot or caster before towing to maximize ground clearance. Never attempt to adjust the drop foot or drop leg when there is any load on the jack.
A swivel jack is a jack that can rotate. If your jack is a swivel jack, lock the plunger pin into a hole in the mounting bracket before raising or lowering the tongue. This prevents unintended rotation during operation.
A pivot tube mount allows the jack to pivot. If your jack 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. The non-beveled side of the pivot tube is welded to the tongue unless otherwise specified on the hardware.
For a bolt-on rack jack: 1) Place the gear housing on the tongue and insert the supplied bolts in holes corresponding to the tongue width. 2) Place the mounting bracket below the tongue with the flat surface against the tongue. 3) Secure with locknuts and torque to 25 ft. lbs. Do not raise the gear housing above the inner tube.
To attach a top-wind handle assembly: 1) Place the washer over the screw stem and then place the handle over the screw stem. 2) Secure the handle to the screw stem with the bolt and nut provided.
To attach a side-wind handle assembly: 1) Insert the long spacer into the roller followed by the thin spacer and the bolt. 2) Secure to the crank stem with the nut provided.
To attach a wheel assembly: 1) Insert the long spacer into the wheel. 2) Set the wheel into the caster body and place the bolt through the caster body and wheel. 3) Secure with the nut provided. For a heavy duty caster, use 4 3/8 inch bolts, washers, and locknuts as shown in the manual. Note: Jack capacity is limited to the lesser of the jack or caster capacity.
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 used in a marine environment, flush the jack assembly and bushings with fresh water and apply fresh lubricant.
The manual does not specify which tools are required for installation. For bolt-on installations, you will need tools to tighten bolts and locknuts to 25 ft. lbs. (torque wrench recommended). For welded installations, an AWS certified welder is required. Contact Cequent Performance Products at 1-800-632-3290 for specific tool recommendations.
The manual states that supplied bolts are included for bolt-on installations. For snap ring models, a snap ring is supplied. For bolt-thru models, a bushing and locknut are supplied. For handle assemblies, bolts, nuts, and washers are supplied. For wheel assemblies, bolts, nuts, and spacers are supplied. Refer to your specific product documentation for a complete hardware list.
Cequent Performance Products manufactures tongue jacks under the following brands: Bulldog, Fulton, Pro-Series, and Reese Towpower. The warranty period varies by brand: five years for Bulldog and Fulton products, and one year for Pro-Series and Reese Towpower products.
No. Tongue jacks are not designed for mounting to round tongues. They are designed for flat or rectangular tongues only.
Torque all mounting bolts to 25 ft. lbs. For A-plate jacks, torque the three 3/8-16 grade 5 bolts to 15-20 ft. lbs.
No. Bolt-on jacks are secured with bolts and locknuts only. Do not weld bolt-on brackets to the tongue. If you need a welded installation, special weld-on brackets are available.
The gap must not exceed 1/16 inch (1.5 mm). Upper bolts should rest on top of the tongue; lower bolts should be less than 1/16 inch from the bottom.
At least annually. For side-wind models, apply automotive grease to internal gearing and lightweight oil to the handle. For top-wind models, apply lightweight oil to the screw stem. In marine environments, flush with fresh water and apply fresh lubricant.
Inspect the snap ring groove and remove any debris. Clean the groove thoroughly before attempting to seat the snap ring again. The snap ring must be fully seated in the groove for proper installation.
Tighten the locknut until there is little movement in the bushing. The bolt should be installed between the trailer tongue and mount, with the jack bracket held by the bushing between the locknut and the mount. Ensure the locknut is tight enough to minimize bushing movement while still allowing the jack to function properly.
The manual does not directly address noise issues. However, the maintenance section recommends lubricating the internal gearing and bushings at least annually. If your jack is making noise, it may need lubrication. For side-wind models, apply automotive grease to the internal gearing and lightweight oil to the handle. For top-wind models, apply lightweight oil to the screw stem. If noise persists after lubrication, contact Cequent Performance Products at 1-800-632-3290.
Check for clearance of the handle, trailer light cables, and coupler after installation. If interference is found, the jack may not be positioned correctly. Reposition the jack to ensure adequate clearance in all positions, including handle swing and swivel positions if applicable. Check for interference again after repositioning.
