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 Powered A-Frame Jack is an electric jack designed to attach to the top surface of a trailer A-frame coupler. It extends to raise the trailer off the tow vehicle's ball and retracts to lower it back down. It includes a built-in circuit breaker, an LED light, and an optional bubble level for leveling the trailer.
No. The manual states that the battery charger is not included. You must provide your own trailer battery (fully charged before use) and charger. The jack connects directly to the positive terminal of the trailer battery.
The manual does not specify a maximum rated capacity in the text. You must refer to the stamped markings or decals on the product itself to determine rated capacity. If uncertain, contact Cequent Performance Products at 800-604-9466 or www.cequentperformanceproducts.com.
The jack is designed to attach to the top surface of an A-frame coupler. The dual mounting pattern allows positioning either facing the tow vehicle or for side operation.
The jack is designed for A-frame couplers only. The manual does not specify compatibility with particular trailer makes, models, years, or bed lengths. If you are unsure whether your trailer is compatible, contact Cequent Performance Products at 800-604-9466 or www.cequentperformanceproducts.com.
The manual instructs you to check for interference if your trailer has a weight distribution kit attached. If your trailer is equipped with one, verify that the jack does not interfere with it during operation to avoid damage.
The jack includes three 3/8" diameter, 1" long, grade 5 bolts and nuts; lock washers; and star washers for mounting. If the Plunger Pin Kit is included, it comes with a plunger pin assembly and drop leg. A removable cap for manual override crank access is also included.
The Plunger Pin Kit is optional. The manual states 'If the Plunger Pin Kit is included with this jack, install per instructions below.' If it is not included with your jack and you wish to add it, contact Cequent Performance Products Customer Service at 1-715-693-1700 or 1-800-604-9466 to order replacement parts.
The manual does not specify which tools are required for installation. Based on the hardware provided (bolts, nuts, washers), you will likely need a wrench or socket set to tighten the 3/8" bolts to 15-20 ft-lbs, and cable ties or equivalent to route the wire lead. Contact the manufacturer if you need clarification on required tools.
The bubble level is optional and only included if your jack is equipped with one. The manual notes 'Bubble Level Set-Up (if equipped)' and provides setup instructions. If your jack does not have a bubble level and you wish to add one, contact Cequent Performance Products.
Yes. The manual explicitly states: 'To avoid accidental shock and/or damage to the electrical system, disconnect the battery ground cable before installation.' Reconnect it after wiring is complete (step 10).
Yes. The first installation step states 'Attach trailer to tow vehicle. Use vehicle's parking brake and chock wheels of trailer.' The jack is installed with the trailer connected to the tow vehicle, with the parking brake engaged and wheels chocked for safety.
Yes. Step 4 instructs you to 'Detach the drop leg of the jack by removing the lynch pin.' The drop leg is then positioned beneath the coupler mounting hole (step 5) before the jack outer tube is placed through the coupler hole (step 6). After mounting bolts are tightened, you reattach the drop leg using the lynch pin (step 12).
Torque the three 3/8" diameter, 1" long, grade 5 bolts to 15-20 ft-lbs. Lock washers must be placed between the bolt head and the top of the jack mounting bracket, and star washers must be used to ensure metal-to-metal contact between jack and coupler for proper grounding.
The jack has a dual mounting pattern that allows two positions: facing the tow vehicle or for side operation. Position the drop leg beneath the coupler mounting hole with the foot on the ground. Place the jack outer tube through the A-frame coupler hole and over the drop leg. Choose the orientation that works best for your setup.
Star washers are used to ensure metal-to-metal contact between the jack and coupler for proper grounding. They must be placed between the bolt head and the top of the jack mounting bracket, along with lock washers, to maintain electrical continuity.
Route the black wire lead from the plastic cover along the trailer to the battery. Attach the wire lead to the trailer using cable ties or equivalent to secure it in place. Connect the wire lead directly to the positive (+) terminal of the battery. The jack has a built-in circuit breaker that automatically trips and resets.
Yes. After connecting the black wire lead from the jack to the positive terminal of the battery, you must reconnect the battery ground cable. This completes the electrical circuit.
Press the motor switch marked 'EXT' to test extension and 'RET' to test retraction. Also check that the light switch turns on the LED light located under the top cover of the jack. After confirming proper operation, reattach the drop leg using the lynch pin or plunger pin assembly, then retract the jack completely.
The Plunger Pin Kit is an optional assembly that replaces the lynch pin. To install: (1) Align grooves of jack tube and plunger pin assembly and slide over bottom of jack tube. (2) Retract plunger pin and slide assembly onto jack, checking that pin passes through both sides of tube. (3) Install drop leg. (4) With plunger pin through both holes of jack tube, tighten clamp to jack and torque to 15-20 ft-lbs. Ensure plunger pin and drop leg operate freely after tightening. (5) Reattach jack to trailer per main installation instructions.
Torque the plunger pin assembly clamp to 15-20 ft-lbs. After tightening, make sure the plunger pin and drop leg operate freely.
The wire lead from the jack is black. It must be routed along the trailer from the plastic cover to the battery and connected directly to the positive (+) terminal.
Yes. The jack has a built-in circuit breaker which automatically trips and resets. This protects the electrical system from overload.
No. The black wire lead from the jack must be connected directly to the positive (+) terminal of the battery only. The battery ground cable provides the negative return path through the coupler's metal-to-metal contact with the jack.
Before operating: (1) Ensure the battery is fully charged. (2) Chock the wheels of the trailer to prevent rolling. (3) Never position any part of your body under or on the path of the jack or load. (4) Do not allow children to play on or around the product. (5) Ensure the supplied pin is fully inserted through both sides of the inner tube and drop tube before using the jack. (6) Secure the load, vehicle and trailer from rolling by blocking wheels.
No. The manual explicitly warns: 'If this product has a drop foot or drop leg, never attempt to adjust the drop foot or drop leg when there is any load on the jack.' Always lower the load completely before adjusting the drop leg.
The jack is designed for vertical loading only. Excessive side forces may cause jack failure and must be avoided. Always apply load directly downward through the coupler.
If electric power is lost, remove the removable cap on top of the plastic cover and insert the manual override crank to raise or lower the jack manually.
After installation: (1) Press the motor switch marked 'EXT' to test extension. (2) Press the switch marked 'RET' to test retraction. (3) Check that the light switch turns on the LED light under the top cover. (4) Reattach the drop leg using the lynch pin or plunger pin assembly. (5) Retract the jack completely. (6) Periodically check mounting hardware for proper torque and tighten if necessary.
The motor is sealed and maintenance-free. However, you must: (1) Maintain the electrical system including the battery and charger (not included). (2) Ensure all connections are tight and free of corrosion. (3) Ensure the jack is properly grounded with the coupler (metal-to-metal contact). (4) Keep the battery fully charged prior to use. (5) Wash with mild soap and water and rinse thoroughly if necessary. (6) Do not direct high-pressure spray at the jack. (7) Periodically oil the pins of the plunger pin assembly. (8) Periodically check mounting hardware for proper torque and tighten if necessary.
The manual states to 'Periodically check mounting hardware for proper torque and tighten if necessary.' It does not specify an exact interval. Inspect the three mounting bolts regularly to ensure they remain tight at 15-20 ft-lbs.
The manual instructs to 'Periodically oil pins of the plunger pin assembly.' It does not specify an exact interval. Regular lubrication will help ensure smooth operation of the plunger pin and drop leg.
No. The manual explicitly states: 'Do not direct a high pressure spray at the Powered A-Frame Jack.' If cleaning is necessary, wash with mild soap and water and rinse thoroughly.
The manual states: 'Make sure the battery is fully charged prior to use.' If the battery is not fully charged, charge it completely before operating the jack. A fully charged battery is necessary for proper jack operation.
To raise the trailer off the ball: (1) Ensure the battery is fully charged. (2) Chock the wheels of the trailer. (3) Open the coupler. (4) Push the 'EXT' button on the motor switch. This will extend the jack. Alternatively, you can use the drop leg to quickly extend the jack. After adjusting the drop leg to the desired level, reattach the lynch pin or plunger pin assembly through both sides of the jack tube.
To lower the trailer onto the ball: (1) Push the 'RET' button on the motor switch. This will retract the jack. (2) After the coupler has fully engaged the ball, continue retracting the jack fully. (3) Close the coupler. (4) After full retraction, you may need to raise the drop leg. (5) Reattach the lynch pin or plunger pin assembly through both sides of the jack tube.
To function the LED light, use the light switch labeled 'ON' and 'OFF'. The LED light is located under the top cover of the jack.
The bubble level only needs to be adjusted during initial setup: (1) Chock the wheels of the trailer. (2) Remove the three bubble level retaining ring screws. (3) Place the bubble level on a known flat surface. (4) Lower the trailer's leveling jacks (if equipped) and the Powered A-Frame jack to properly support and level the trailer using the bubble level as a guide. (5) Once level, return the bubble level to the jack and adjust the three retaining screws so the bubble is centered. After this initial setup, you can level your trailer in minutes by watching the bubble. No further adjustments are necessary.
Yes. The manual states: 'The drop leg may also be used to quickly extend the jack.' However, after adjusting the drop leg to the desired level, you must reattach the lynch pin or plunger pin assembly through both sides of the jack tube before using the jack.
First, ensure the battery is fully charged. The manual states 'Make sure the battery is fully charged prior to use.' If the battery is fully charged and the jack still does not operate, check that all electrical connections are tight and free of corrosion, and that the jack is properly grounded with the coupler (metal-to-metal contact). If the problem persists, contact Cequent Performance Products at 1-800-604-9466.
Check that the light switch is set to 'ON'. Verify that the battery is fully charged and that all electrical connections are tight and free of corrosion. Ensure the jack is properly grounded with the coupler (metal-to-metal contact). If the light still does not turn on, contact Cequent Performance Products at 1-800-604-9466.
Tighten the three 3/8" diameter mounting bolts to 15-20 ft-lbs using a wrench or socket. Ensure lock washers are placed between the bolt head and the top of the jack mounting bracket, and that star washers are in place to ensure metal-to-metal contact between jack and coupler for proper grounding. Periodically check mounting hardware for proper torque and tighten if necessary.
When installing the Plunger Pin Kit, ensure that the grooves of the jack tube and plunger pin assembly are properly aligned before sliding the assembly over the bottom of the jack tube. Retract the plunger pin, slide the assembly onto the jack, and verify that the pin passes through both sides of the tube. If it does not, realign the grooves and try again.
After tightening the plunger pin assembly clamp to 15-20 ft-lbs, verify that the plunger pin and drop leg operate freely. If they do not move smoothly, loosen the clamp slightly and check for misalignment or obstruction. Ensure the pin is fully inserted through both sides of the jack tube. Periodically oil the pins of the plunger pin assembly to maintain smooth operation.
Proper grounding requires metal-to-metal contact between the jack and coupler. Ensure that: (1) Star washers are placed between the bolt head and the top of the jack mounting bracket. (2) Lock washers are also in place. (3) All three mounting bolts are tightened to 15-20 ft-lbs. (4) The battery ground cable is reconnected after wiring. (5) All electrical connections are tight and free of corrosion. If grounding is still poor, loosen the bolts, clean the contact surfaces, and retighten.
The bubble level only needs to be adjusted during initial setup. If the bubble is not centered: (1) Ensure the trailer is level using the leveling jacks (if equipped) and the Powered A-Frame jack. (2) Place the bubble level on a known flat surface to verify it is accurate. (3) Adjust the three retaining screws on the bubble level until the bubble is centered. Once properly centered, no further adjustments are necessary.
