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 jack capacity is limited to the lesser of the jack, footplate, or caster wheel capacity. The exact maximum rated capacity is stamped on markings or decals on the product itself. If you cannot find the capacity marking or are uncertain, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.
No. These jacks are not designed for mounting to round tongues. They are designed for flat tongues. If you have a round tongue, contact Cequent Performance Products at 1-800-632-3290 to discuss alternative solutions.
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. If the gap is larger, the mounting will not be secure.
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. After installation is complete, check for interference again, including clearance of the handle, trailer light cables, and coupler.
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 of the tongue. 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. The upper bolts should rest on the top of the tongue. The lower bolts should be less than 1/16 inch from the bottom of the tongue. 3) Secure with locknuts and torque to 25 ft. lbs. 4) Check for clearance of handle, trailer light cables, and coupler.
All bolts used in bolt-on mounting must be torqued to 25 ft. lbs. This applies to both rack jack and mounting bracket installations.
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.
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. Use a 3/16 inch fillet weld. 3) Bolt the jack A-plate to the coupler using three 3/8-16 grade 5 bolts with washers, torqued to 15-20 ft. lbs. 4) Weld the recommended support plate to the bottom of the trailer frame using a 3/16 inch fillet weld. 5) If your jack is a plain mount type, it may be mounted directly to a coupler with a 3/16 inch fillet weld. 6) Rack jacks with a similar A-plate incorporated into their design may be attached according to these instructions. It is recommended to attach a bottom support plate to the bottom of the tongue.
Welding is required only for certain mounting styles: direct-mount, A-plate (weld-on), and weld-on pivot tube models. 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.
For direct-mount installation: 1) All welding must be performed by an AWS certified welder. 2) Place the jack at the desired location. 3) Weld 1 inch in 2 locations on both sides of the jack using a 3/16 inch fillet weld. The same welding instructions apply to other weld-on mounts.
For weld-on pivot tube mounting (round and square pivot tubes): 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 inch 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.
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 its lowest position.
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 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.
If this product is a swivel jack, lock the plunger pin into a hole in the mounting bracket before raising or lowering the tongue.
If this 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.
Operator and bystanders should never position any part of body under any portion of this product or the load being supported. Secure the load, vehicle and trailer from rolling (by blocking wheels) when operating jack or coupling trailer. These jacks are designed for vertical loading. Excessive side forces may cause jack failure and must be avoided. Do not allow children to play on or around this product or the load being supported. This product is not intended to be used as a transport device for the implement it is attached to. Minimize movement of implement while jack is under load.
If this product is a rack jack, do not raise the gear housing above the inner tube.
The following procedures should be performed at least annually. For side-wind models, the internal gearing and bushings of the jack must be kept lubricated. For top-wind models, apply a lightweight oil to the screw stem. If this product is used in a marine environment, flush the jack assembly and bushings with fresh water, and apply fresh lubricant.
For side-wind models, 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.
For top-wind models, apply a lightweight oil to the screw stem.
If this product is used in a marine environment, flush the jack assembly and bushings with fresh water, and apply fresh lubricant.
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.
To attach a 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 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.
For heavy duty caster installation: Use 4 3/8 inch bolts, washers, and locknuts as shown in the manual. The jack capacity is limited to the lesser of the jack or caster capacity.

Before installing the snap ring, inspect the snap ring groove and remove any debris. Seat the snap ring fully into the groove. If debris is present, clean the groove thoroughly before attempting to install the snap ring again.
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.
For side-wind models, the internal gearing and bushings must be kept lubricated. 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 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 equipped, the axle bolt and nut assembly of the caster wheel must be lubricated with lightweight oil. Apply the oil and check that the bolt and nut are not over-tightened, which would restrict rotation.
If this product is used in a marine environment, flush the jack assembly and bushings with fresh water, and apply fresh lubricant. This will help prevent rust and corrosion. For non-marine environments, ensure the jack is kept dry and lubricated according to the maintenance schedule.
