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 manual is model F3282ML, Revision D, dated 6077. This covers Cequent Performance Products tongue jacks including Bulldog, Fulton, Pro-Series, and Reese Towpower brands.
Tongue jacks are available in six mounting types: bolt-on rack jack, bolt-on mounting bracket, snap ring, bolt-thru, direct-mount weld-on, A-plate (bolt-on or weld-on), and weld-on pivot tube (round or square). The correct type depends on your trailer design and coupler type. A-plate jacks are specifically designed for trailers with A-plate couplers.
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.
No. A-plate jacks are designed specifically for mounting to trailers with A-plate couplers only. If your trailer has a different coupler type, you will need a different mounting type such as bolt-on, snap ring, bolt-thru, or pivot tube.
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 for interference again after installation is complete. Also verify the correct mounting hole pattern for your tongue size and that the gap between mounting bolts and tongue does not exceed 1/16 inch.
Yes, if your jack requires welding. The manual states: 'All welding must be performed by an AWS certified welder.' This applies to direct-mount, A-plate weld-on, and weld-on pivot tube installations. Bolt-on and snap ring models do not require welding.
1) Place the gear housing on the tongue and insert the supplied bolts into 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. Verify the correct mounting hole pattern for your tongue size and that the gap between mounting bolts and tongue does not exceed 1/16 inch.
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. 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. The gap between mounting bolts and tongue must not exceed 1/16 inch.
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) 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.
A-plate jacks are designed for 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 inch 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 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.
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. Align one set of pivot mount holes vertically. 4) Mate the jack to the pivot tube and secure with the supplied pin. Pivot tubes can be round or square.
Torque all locknuts to 25 ft. lbs. This applies to both bolt-on rack jacks and bolt-on mounting bracket installations.
Use three 3/8-16 grade 5 bolts with washers and torque to 15-20 ft. lbs. when bolting the jack A-plate to the coupler.
All weld-on tongue jack installations require a 3/16 inch fillet weld. This applies to direct-mount, A-plate weld-on, and weld-on pivot tube installations. All welding must be performed by an AWS certified welder.
The gap between the mounting bolts and the tongue must not exceed 1/16 inch (1.5 mm). This applies to bolt-on rack jacks and bolt-on mounting bracket installations.
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.
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 heavy duty casters, 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.
Fully retract and rotate the jack before towing. If using an optional drop foot or caster, always remove the drop foot or caster before towing to maximize ground clearance.
Before manually moving the trailer, crank the jack to the 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. 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.
Never exceed the maximum rated capacity. The jack capacity is limited to the lesser of the jack, footplate, or caster wheel capacity. Refer to the stamped markings or decals on your product to obtain the rated capacity. If uncertain, contact Cequent Performance Products at 1-800-632-3290 or www.cequentgroup.com.

For side-wind models, the internal gearing and bushings of the jack must be kept lubricated. 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.
