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 model number is F3282ML, Revision D 6077. This manual covers multiple tongue jack mounting styles and handle types manufactured by Cequent Performance Products.
No. These jacks are not designed for mounting to round tongues. You must use a tongue with a flat surface suitable for bolt-on, snap ring, or bolt-thru mounting, or choose a weld-on mounting option if your application requires it.
The gap between the mounting bolts and the tongue must not exceed 1/16 inch (1.5 mm). This ensures proper seating and load distribution of the jack on the tongue.
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 jack mounting style.
For A-plate mounting to the coupler, use three 3/8-16 grade 5 bolts with washers. For heavy duty caster attachment, use 4 bolts of 3/8 inch diameter with washers and locknuts. All other bolt-on installations use the supplied bolts and locknuts.
Bolts and locknuts are supplied with bolt-on and snap ring models. For A-plate installations, you must supply three 3/8-16 grade 5 bolts with washers. For heavy duty caster attachment, you must supply 4 bolts of 3/8 inch diameter with washers and locknuts. Weld-on models do not require bolts.
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 clearance of the handle, trailer light cables, and coupler.
All bolt-on mounting fasteners must be torqued to 25 ft. lbs. (3.5 m/kg). This applies to both the gear housing mounting bolts and the mounting bracket locknuts.
When bolting the jack A-plate to the coupler, torque the three 3/8-16 grade 5 bolts with washers to 15-20 ft. lbs. (2-2.7 m/kg).
No. Bolt-on jacks use existing holes in the tongue and mounting straps. You must ensure the correct mounting hole pattern for your tongue size, but no drilling is required. However, if you are installing an A-plate jack with a weld-on support plate, welding is required and must be performed by an AWS certified welder.
No. 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 Cequent Performance Products at 1-800-632-3290 to obtain the correct weld-on brackets.
All welding must be performed by an AWS certified welder. For direct-mount installations, weld 1 inch in 2 locations on both sides of the jack using a 3/16 inch fillet weld. For A-plate installations, use a 3/16 inch fillet weld. For pivot tube mounting, weld all around the pivot tube with a 3/16 inch fillet weld. A support plate welded to the bottom of the trailer frame is recommended for A-plate installations, also using a 3/16 inch fillet weld.
The 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.
The manual does not describe any electrical connections or wiring requirements for tongue jacks. These are mechanical devices operated by hand crank (side-wind or top-wind models) and do not require electrical power.
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. If the jack is a swivel type, lock the plunger pin into a hole in the mounting bracket before raising or lowering the tongue.
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. Before manually moving the trailer, crank the jack to its lowest position. These jacks are designed for vertical loading only; excessive side forces may cause jack failure and must be avoided.
Yes. 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.
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 should be welded to the tongue unless otherwise specified on the hardware.
Before installing the snap ring, inspect the snap ring groove and remove any debris. Seat the snap ring fully into the groove to ensure proper installation and safe operation.
No. This product is not intended to be used as a transport device for the implement it is attached to. Minimize movement of the implement while the jack is under load.
If your product is a rack jack, do not raise the gear housing above the inner tube. Raising it beyond this point may cause damage or failure.
After installation is complete, check for interference again in all positions, including handle swing and swivel positions if applicable. Verify clearance of the handle, trailer light cables, and coupler. Ensure all fasteners are torqued to the correct specification and that the jack operates smoothly through its full range of motion.
The following procedures should be performed at least annually: For side-wind models, apply automotive grease to the internal gearing and apply lightweight oil to the handle unit at both sides of the tube. For top-wind models, apply lightweight oil to the screw stem. If equipped with a caster wheel, lubricate the axle bolt and nut assembly with lightweight oil. If 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.
For top-wind models, apply a lightweight oil to the screw stem. This should be done at least annually.
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.
The jack capacity is limited to the lesser of the jack or caster capacity. Use 4 bolts of 3/8 inch diameter with washers and locknuts to attach the heavy duty caster, as shown in the manual.
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.
No. These jacks are not designed for mounting to round tongues. They require a flat tongue surface.
The gap must not exceed 1/16 inch (1.5 mm) to ensure proper seating and load distribution.
Bolts and locknuts are supplied. For A-plate installations, you must supply three 3/8-16 grade 5 bolts with washers.
Torque all bolt-on mounting fasteners to 25 ft. lbs. (3.5 m/kg). A-plate bolts torque to 15-20 ft. lbs. (2-2.7 m/kg).
Fully retract and rotate the jack. Remove any optional drop foot or caster before towing. Lock the plunger pin on swivel jacks.
Perform maintenance at least annually. Lubricate internal gearing and bushings with automotive grease for side-wind models; apply lightweight oil to handle and screw stem for top-wind models. Flush with fresh water if used in marine environments.
Before installing the snap ring, inspect the snap ring groove and remove any debris. Seat the snap ring fully into the groove. If it still does not seat properly, the groove may be damaged. Replace the jack or contact Cequent Performance Products at 1-800-632-3290.
For side-wind models, ensure the internal gearing and bushings are properly lubricated with automotive grease. Rotate the handle to distribute grease evenly. For top-wind models, apply lightweight oil to the screw stem. If the handle assembly is loose, verify that the bolt and nut securing the handle to the crank stem (or screw stem) are tight.
For side-wind models, apply a small amount of automotive grease to the internal gearing using the lubrication point on the side of the jack near the crank, or by removing the jack cover. Rotate the handle to distribute the grease evenly. For top-wind models, apply lightweight oil to the screw stem. If the problem persists, the jack may have internal damage and should be replaced.
Ensure the pivot pin is fully inserted through both sides of the pivot tube and the pivot mount. If it continues to come loose, the pin or mounting holes may be damaged. Replace the pin or contact Cequent Performance Products at 1-800-632-3290 for replacement parts.
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 will not fully insert, check for debris or damage in the holes. Clean or replace the pin as needed. Do not use the jack until the pin is fully inserted.
If your jack is a swivel type, ensure the plunger pin is locked into a hole in the mounting bracket before raising or lowering the tongue. If the pin is not locked, the jack may bind or not operate smoothly. Lock the pin and try again.
For side-wind models, the internal gearing may need lubrication. Apply a small amount of automotive grease to the internal gearing by removing the jack cover or using the lubrication point on the side of the jack near the crank. Rotate the handle to distribute the grease evenly. For top-wind models, apply lightweight oil to the screw stem. If noise persists, internal damage may have occurred and the jack should be replaced.
