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 types: bolt-on rack jacks, snap ring models, bolt-thru models, A-plate jacks, direct-mount (weld-on) jacks, and pivot tube (weld-on) jacks. Each type is designed for different trailer configurations and mounting methods.
No. The manual explicitly states: "These jacks are not designed for mounting to round tongues." You must have a flat or A-plate coupler tongue to use these jacks.
The jack capacity is limited to the lesser of three factors: the jack capacity, the footplate capacity, or the caster wheel capacity (if equipped). You must refer to the stamped markings or decals on your specific product to obtain the rated capacity. If uncertain, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.
Bolt-on jacks include supplied bolts and locknuts for securing the gear housing and mounting bracket to the tongue. The exact number and size depend on your tongue width. The manual specifies that 4 bolts are used through the mounting bracket and mounting straps, with upper bolts resting on top of the tongue and lower bolts positioned less than 1/16" from the bottom.
Yes. 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 and swivel positions if applicable. You must check for interference again after installation is complete.
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. After installation, check for clearance of the handle, trailer light cables, and coupler.
1) Place the jack against the tongue and position the mounting straps on the opposite side. Align the holes in the mounting bracket with the holes in the mounting straps. 2) Insert the 4 bolts through the mounting bracket and mounting straps. Upper bolts should rest on the top of the tongue; lower bolts should be less than 1/16" from the bottom. 3) Secure with locknuts and torque to 25 ft. lbs. 4) Check for clearance of handle, trailer light cables, and coupler. The gap between mounting bolts and tongue must not exceed 1/16".
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.
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.
A-plate jacks are designed for mounting to trailers with A-plate couplers. It is recommended to attach a bottom support plate to the bottom of the tongue. 1) All welding must be performed by an AWS-certified welder. 2) If the A-plate is separate from the jack, align the jack (and foot, if equipped) with the jack and coupler as desired before welding using a 3/16" fillet weld. 3) Bolt the jack A-plate to the coupler using three 3/8-16 grade 5 bolts with washers, torque to 15-20 ft. lbs. 4) Weld the recommended support plate to the bottom of the trailer frame using a 3/16" fillet weld. 5) If your jack is a plain mount type, it may be mounted directly to a coupler with a 3/16" fillet weld. 6) Rack jacks with a similar A-plate incorporated into their design may be attached according to these instructions.
1) All welding must be performed by an AWS-certified welder. 2) Place the jack at the desired location. 3) Weld 1" in 2 locations on both sides of the jack using a 3/16" fillet weld. The same welding instructions apply to other weld-on mounts.
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 unless otherwise specified on hardware. 3) Place the weld-on pivot tube against the tongue and weld all around with a 3/16" fillet weld. Align one set of pivot mount holes vertically. 4) Mate the jack to the pivot tube and secure with the supplied pin.
Welding is required only for certain mounting types: A-plate (weld-on), direct-mount, and pivot tube (weld-on) jacks. Bolt-on, snap ring, and bolt-thru models do not require welding. All welding must be performed by an AWS-certified welder. Do not attempt to weld bolt-on brackets or straps to the tongue; special brackets are available for weld-on applications.
Torque all locknuts to 25 ft. lbs. for bolt-on rack jacks and bolt-on mounting brackets.
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.
Use a 3/16" fillet weld for all weld-on tongue jack installations, including A-plate, direct-mount, and pivot tube mounts. Weld 1" in 2 locations on both sides of direct-mount jacks.
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.
Never position any part of your body under any portion of the 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. Do not allow children to play on or around the product or the load being supported. These jacks are designed for vertical loading only; excessive side forces may cause jack failure and must be avoided. Before manually moving the trailer, crank the jack to its lowest position.
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. If using an optional drop foot or caster, always remove it before towing to maximize ground clearance. Never attempt to adjust the drop foot or drop leg when there is any load on the jack.
Make certain the pivot pin is fully inserted through both sides of the pivot tube and the pivot mount before using the jack.
Lock the plunger pin into a hole in the mounting bracket before raising or lowering the tongue.
Do not raise the gear housing above the inner tube. This is a critical safety limitation to prevent jack failure.
The following procedures should be performed at least annually. For side-wind models, the internal gearing and bushings must be kept lubricated. For top-wind models, apply 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.
Apply a small amount of automotive grease to the internal gearing by removing the jack cover, or if equipped, use 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. A lightweight oil must be applied to the handle unit at both sides of the tube for side-wind models. If equipped, the axle bolt and nut assembly of the caster wheel must also be lubricated with the same lightweight oil.
Apply a lightweight oil to the screw stem.
Flush the jack assembly and bushings with fresh water and apply fresh lubricant.
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" bolts, washers, and locknuts as shown in the manual. Note: Jack capacity is limited to the lesser of the jack or caster capacity.
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.
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.
