Capacity alone is not enough to choose: the products range from an 8,000-pound single leg to dual systems, and some listings specify bolt-on or weld-on mounting. Check the trailer’s required lift, mounting arrangement, and existing hydraulics before selecting a product.

Detailed Reviews: Best Hydraulic Jack For Gooseneck Trailer

#1 · Best Overall
1. Johnson Trailer Parts Dexter 24K Kit
- Load Capacity: 24,000 lb
- Material: Steel
- Compatible with Vehicle Type: Trailer
Best for: Synchronized dual-jack lifting.
Why it ranks #1: Explicitly listed for gooseneck trailers, this complete system pairs two 12,000-pound jacks with a KTI double-acting pump and a flow divider.
Two 12,000-pound hydraulic jacks and a flow divider give this Dexter kit a stated 24,000-pound combined lifting capacity with synchronized operation. That pairing suits buyers who want both trailer jacks to raise evenly, while the KTI double-acting pump provides push-button power-up and power-down control for gooseneck, dump, and cargo trailers.
The flow divider distributes fluid evenly to both jacks, connecting the dual 12,000-pound cylinders with the kit's 24,000-pound lifting claim for coordinated raising. Each jack uses a 2-by-20-inch cylinder, and the KTI pump is rated at 2 GPM and up to 3,200 PSI. Double-acting operation powers both raising and lowering, so the push-button workflow controls movement in both directions. The kit includes hoses, jack covers, and the hydraulic power unit.
- Dual 12,000-pound jacks
- 24,000-pound combined lifting capacity
- Flow divider for synchronized operation
- Double-acting KTI pump
- The dual-jack system weighs more to handle and install than the listed single-jack kits.
Skip it if you need one jack rather than a dual setup; the Dexter 12,000 lb Hydraulic Trailer Jack Kit uses a single power jack.
This kit fits gooseneck owners seeking synchronized lifting from two powered jacks, and also lists dump and cargo trailers as applications. Its dual-jack layout and 24,000-pound combined rating are the key fit considerations.

#2 · Best Single-Jack Kit
2. Johnson Trailer Parts Dexter 12K Kit
- Load Capacity: 12,000 lb
- Material: Steel
- Compatible with Vehicle Type: Trailers
Best for: Single-jack powered setup.
Why it ranks #2: A gooseneck-listed single-jack kit with 12,000-pound capacity, KTI double-acting pump, and controlled power-up and power-down operation.
A single 12,000-pound jack paired with a KTI double-acting pump gives this Dexter kit powered raising and lowering without a dual-jack arrangement. Its 2-by-20-inch cylinder and push-button operation suit gooseneck, dump, and cargo trailer owners who want a complete hydraulic unit for one lifting point.
The 12,000-pound single jack uses a 2-by-20-inch cylinder, while the KTI power unit is specified at 2 GPM and up to 3,200 PSI. Together, those features support the kit's push-button lifting workflow; double-acting hydraulics also power the descent rather than limiting powered control to raising. The package lists a jack cover, battery cables, and 48-inch hydraulic hoses, giving buyers several system components in one kit.
- 12,000-pound single-jack capacity
- KTI double-acting pump
- Push-button power-up and power-down
- Includes battery cables and 48-inch hoses
- It is a single-jack kit, not a synchronized dual-jack setup.
Skip it if you want two synchronized jacks and 24,000-pound combined capacity; the Dexter 24,000 lb Hydraulic Trailer Jack Kit supplies a dual setup.
Choose this Dexter kit if your gooseneck setup calls for one 12,000-pound powered lifting point and controlled movement in both directions. Buyers seeking synchronized support from two jacks should consider its single-jack configuration a boundary.

#3 · Best Hydraulic Add-On
3. Johnson Trailer Parts Dexter Add-On Kit
- Load Capacity: 12,000 lb
- Material: Steel
- Compatible with Vehicle Type: RVs, Trailers
Best for: Existing-hydraulic-system add-on.
Why it ranks #3: Listed for gooseneck use, this 12,000-pound single jack includes a selector valve and hoses for connection to an existing hydraulic power unit.
A billet aluminum six-port selector valve lets this Dexter 12,000-pound jack kit connect to an existing hydraulic power unit, avoiding replacement of the current system. Its single 2-by-20-inch-cylinder jack brings push-button lifting to dump, cargo, and gooseneck trailers, making system integration the central buyer consideration.
The add-on kit is intended to connect to an existing hydraulic power unit, and its selector valve manages hydraulic flow between the jack and other functions. That can make it a practical route to add one lifting point while retaining a current system. The single jack has a 12,000-pound capacity and a 2-by-20-inch cylinder; included 48-inch hoses and adapter fittings support the stated hydraulic connection workflow. Push-button operation provides the listed control method.
- 12,000-pound single-jack capacity
- Six-port billet aluminum selector valve
- Connects to an existing hydraulic power unit
- Includes 48-inch hoses and adapter fittings
- It requires an existing hydraulic power unit, which is not included in the listed components.
Skip it if you lack an existing hydraulic power unit; the Dexter 12,000 lb Hydraulic Trailer Jack Kit includes a KTI pump.
Choose this Dexter add-on if your gooseneck already has a hydraulic power unit and you want one 12,000-pound jack with selector-valve control. The existing-system requirement is its key compatibility boundary.

#4 · Center-Tube Mount
4. EQ Systems AJ 1/24
- Load Capacity: 8,000 lbs
- Material: steel
- Compatible with Vehicle Type: Gooseneck trailers
Best for: Gooseneck living-quarter fit.
Why it ranks #4: Designed to bolt onto a gooseneck trailer’s center tube, it provides 8,000-pound capacity, 24 inches of stroke, and a manual override screw drive.
A 24-inch stroke paired with an 8,000-pound capacity gives the EQ Systems single-leg jack useful lifting range for gooseneck trailers with living quarters up to an 11-foot short wall. Its manual override screw drive also provides an operating option alongside the hydraulic system, for buyers prioritizing a specified trailer configuration.
The square tube-in-tube steel construction supports the listed 8,000-pound capacity, while the 24-inch stroke gives the jack lifting travel for trailer setup. A single-function pump and single-switch gear control with key keep operation to one control point; the manual override screw drive adds a mechanical alternative. Universal mounting brackets are listed, and the jack is intended to bolt onto a gooseneck trailer's center tube. The stated living-quarter fit extends to an 11-foot short wall.
- 8,000-pound capacity
- 24-inch stroke
- Manual override screw drive
- Single-switch gear control with key
- Its 8,000-pound capacity is lower than the listed 12,000-pound single-jack options.
Skip it if you need a listed 12,000-pound single-jack capacity; the Chief 12K Hydraulic Trailer Jack offers that rating and 24 inches of travel.
Choose this EQ Systems jack for a gooseneck owner whose living quarters have a short wall up to 11 feet and who values manual override. Its 8,000-pound rating is the boundary to weigh against heavier requirements.

#5 · Articulating Foot
5. Chief 12K Hydraulic Jack
- Load Capacity: 12,000 lb
- Material: Steel
- Compatible with Vehicle Type: Trailer
Best for: Uneven-ground gooseneck support.
Why it ranks #5: Its 12,000-pound lift and hold capacity, 24-inch travel, and 360-degree articulating foot offer useful listed features for trailer setup.
A 360-degree articulating foot lets the Chief 12K jack adjust its contact on uneven surfaces, a practical detail for gooseneck and utility trailer setups. It pairs that foot with 12,000 pounds of lift and hold capacity, 24 inches of travel, and double-acting operation for powered movement in both directions.
The articulating foot can turn through 360 degrees, giving the jack a contact feature specifically stated for uneven surfaces. Its 12,000-pound lift and hold capacity pairs with 24 inches of travel for trailer positioning, while double-acting hydraulics support powered raising and lowering. The jack is bolt-on ready, which gives installation a stated approach, and its 3,000 PSI operating-pressure rating defines a system specification. Upgraded quad seals are listed to improve holding and reduce bypass.
- 12,000-pound lift and hold capacity
- 360-degree articulating foot
- 24 inches of travel
- Upgraded quad seals
- The jack is listed as bolt-on ready, but the supplied details do not include a hydraulic power unit.
Skip it if you want a complete kit with a listed power unit; the Dexter 12,000 lb Hydraulic Trailer Jack Kit includes a KTI pump.
Pick the Chief for a trailer owner prioritizing an articulating foot, stated holding capacity, and bolt-on readiness on uneven terrain. The supplied listing does not specify a power unit, so that system detail matters.

6. Primary Mover PFJ-2-ADS-K
- Load Capacity: 12000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
Best for: Weld-on dual-jack lifting.
Why it ranks #6: The dual 12,000-pound jack configuration provides 24,000 pounds of stated combined lifting capability, but the listing describes a weld-on setup.
Two 12,000-pound jacks give this Primary Mover kit a stated 24,000-pound lifting capability, with a weld-on configuration for buyers planning a permanent mounting approach. Its hydraulic system replaces manual cranking with powered lifting and lowering, making the dual-jack capacity and installation style the defining fit considerations.
The 12,000-pound-by-two jack arrangement is presented as 24,000 pounds of lifting capability, giving buyers a dual-jack configuration rather than a single lifting point. The hydraulic system provides powered raising and lowering, avoiding manual cranking in the listed workflow. Its weld-on style identifies the mounting approach, and the included bracket is specified as a component. The listed 140-pound weight is also relevant when moving the kit into position for installation.
- Two 12,000-pound jacks
- 24,000-pound stated lifting capability
- Hydraulic powered raising and lowering
- Weld-on mounting style
- The listed 140-pound weight makes handling and positioning the dual-jack kit demanding.
Skip it if you need a bolt-on single jack rather than a weld-on dual setup; the Primary Mover 12K Bolt On kit matches that installation style.
This Primary Mover kit suits trailer owners planning weld-on installation and seeking the stated capacity of two powered 12,000-pound jacks. Its dual layout, 140-pound listed weight, and mounting approach deserve consideration before installation.

7. Primary Mover PFJ-1-MB-K
- Load Capacity: 12,000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
Best for: Bolt-on single-jack installation.
Why it ranks #7: This 12,000-pound bolt-on kit offers a hydraulic power unit and a dual holding valve, though the listing does not specifically identify gooseneck compatibility.
A bolt-on 12,000-pound jack kit with a hydraulic power unit gives the Primary Mover a defined installation style for buyers who want powered trailer lifting without manual cranking. Its double-acting system and dual holding valve address both controlled movement and stability during operation, making those details central to the fit decision.
The 12,000-pound lifting capability is paired with a power unit that operates at the touch of a button, replacing manual cranking in the listed workflow. Double-acting operation supports powered movement, while the dual holding valve is specified to provide stability during use. The kit's bolt-on style and included bracket give installers a stated mounting approach; at 120 pounds, handling and positioning the assembly are practical installation considerations.
- 12,000-pound lifting capability
- Hydraulic power-unit operation
- Double-acting system
- Dual holding valve for stability
- The listed kit weighs 120 pounds, making positioning and installation a substantial handling task.
Skip it if you need a lighter listed single-jack kit; the Primary Mover 12,000 lb Jack Weld On weighs 60 pounds.
This Primary Mover suits a trailer owner seeking a 12,000-pound powered jack with bolt-on mounting and a holding valve. Account for the 120-pound listed weight when planning to position and secure the kit.

8. Primary Mover PFJ-1-ADS-K
- Load Capacity: 12,000 lb

- Compatible with Vehicle Type: Trailer
Best for: Weld-on single-jack kit.
Why it ranks #8: A 12,000-pound hydraulic jack kit with a dual holding valve, listed as a weld-on style; gooseneck compatibility is not specified.
A 60-pound listed weight and weld-on mounting style distinguish this Primary Mover single-jack kit for buyers planning a welded installation. The 12,000-pound hydraulic jack adds powered lifting without manual cranking, while its dual holding valve is specified to support stability during operation and hitching.
The 12,000-pound lifting capability pairs with a hydraulic system that operates at the touch of a button, providing powered movement in place of manual cranking. A dual holding valve is listed to support stability during operation, which matters when positioning a trailer for hitching. The weld-on style gives the kit a defined mounting approach, and the 60-pound listed weight is a handling consideration during installation. A bracket is included.
- 12,000-pound lifting capability
- Hydraulic button-operated lifting
- Dual holding valve for stability
- Weld-on mounting style
- The weld-on mounting style is less suited to buyers seeking a bolt-on installation.
Skip it if you want a bolt-on mounting approach instead of welding; the Primary Mover 12K Bolt On hydraulic jack kit is the listed alternative.
This Primary Mover suits a trailer owner who plans weld-on mounting and wants one powered 12,000-pound jack with a holding valve. Its installation style is the key boundary for buyers choosing a mounting method.

9. Primary Mover PFJ-12K
- Load Capacity: 1.2E+4 lb
- Material: steel
- Compatible with Vehicle Type: Trailer
Best for: Weld-on powered jack.
Why it ranks #9: This 12,000-pound hydraulic jack includes a bracket, but its listed vehicle type is trailer rather than a specifically identified gooseneck.
A 12,000-pound lifting capacity paired with double-acting hydraulics gives this Primary Mover jack powered trailer movement in both directions without manual cranking. Its weld-on style identifies the mounting approach, while the dual holding valve is listed to support stability during operation, including when preparing to hitch.
The jack's stated 12,000-pound capacity and hydraulic power operation suit buyers seeking powered trailer lifting rather than manual cranking. Double-acting operation supports movement in both directions, while the dual holding valve is specified to provide stability during use. Its weld-on style sets an installation expectation, and the included bracket is listed as a component. At 60 pounds, the jack's stated weight is relevant when handling and positioning it for mounting.
- 12,000-pound lifting capacity
- Double-acting hydraulic operation
- Dual holding valve for stability
- Weld-on style with bracket included
- Its weld-on mounting style does not suit buyers seeking a bolt-on installation.
Skip it if you want bolt-on installation; the Primary Mover Hydraulic Trailer Jack 12K Bolt On kit offers that mounting style.
Choose this Primary Mover for a trailer installation planned around welding and a single powered 12,000-pound jack. Its double-acting hydraulics and holding valve suit powered operation, but the mounting method is a clear fit consideration.

#10
10. RAM PREMIUM HJ-15008
- Load Capacity: 15000 lb
- Material: steel
- Compatible with Vehicle Type: Trailer
Best for: Remote-operated high-travel jack.
Why it ranks #10: The self-contained jack offers a corded remote and 12,000-pound lift capacity, but its listing does not specifically identify gooseneck compatibility.
A 24.2-inch travel range and a 12-foot corded remote give this RAM PREMIUM jack a combination of lifting reach and control from a distance. Its self-contained hydraulic unit and 12,000-pound lift capacity suit trailer owners seeking an integrated powered jack, with a pivoting foot pad for uneven surfaces.
The jack lists 15,000 pounds of support capacity and 12,000 pounds of lift capacity, making the distinction important when matching it to a trailer task. Its 59-inch extended height, 34.8-inch retracted height, and 24.2-inch travel define the available movement. A self-contained pump with a 500-watt, 12-volt DC motor powers double-acting operation, while the 12-foot corded remote keeps the control in hand. The pivoting foot pad addresses uneven ground.
- 12,000-pound lift capacity
- 24.2 inches of travel
- Self-contained hydraulic pump
- 12-foot corded remote and pivoting foot pad
- The 12-foot control is corded, so operation remains tethered to the jack.
Skip it if you prefer a bolt-on kit with a listed dual holding valve; the Primary Mover 12K Jack Weld On lists that feature.
This RAM PREMIUM fits trailer owners who value a self-contained pump, substantial stated travel, and remote operation, including on uneven surfaces. The lift rating is 12,000 pounds; its corded control is a relevant operating boundary.

View on AmazonCheck mounting and hydraulic-system compatibility
Mounting and hydraulic connections can be the trap when a jack’s capacity looks suitable. The EQ Systems AJ 1/24 is explicitly designed to bolt onto a gooseneck trailer’s center tube, while several Primary Mover listings identify their style as bolt-on or weld-on. Those labels are not interchangeable instructions: verify the trailer’s frame, available mounting points, and whether the product’s bracket or welding arrangement matches before ordering.
Hydraulic integration also varies. Johnson Trailer Parts Dexter 12K Kit includes a KTI pump, whereas Johnson Trailer Parts Dexter Add-On Kit is designed to connect to an existing hydraulic power unit and includes a selector valve.
A kit that requires an existing power unit may not be a complete standalone system for your setup. Check the included components and confirm hose, fitting, and control compatibility with the trailer or its existing system.
Understand capacity, stroke, and stability as separate checks
A higher stated capacity does not by itself establish that a jack suits a particular trailer. The products range from the 8,000-pound EQ Systems AJ 1/24 to kits described with two 12,000-pound jacks, but the listings do not provide a method for calculating the load your trailer places on the jack or jacks. The EQ jack lists 24 inches of stroke; the Chief 12K lists 24 inches of travel and a 360-degree articulating foot.
RAM PREMIUM HJ-15008 lists 24.2 inches of travel and a pivoting foot pad. These differences matter when considering required lift range and ground contact, but they do not replace checking the trailer’s specifications or operating instructions.
In particular, do not infer that paired jack capacities automatically equal a safe rating for every loading or support situation. Match the stated capacity and travel to the trailer requirements and installation guidance.
How to Choose a Gooseneck Hydraulic Jack
Capacity and number of jacks
Choose a capacity and jack arrangement that match your trailer’s requirements, rather than selecting by the largest number alone. The listings span a single 8,000-pound jack from EQ Systems AJ 1/24, single 12,000-pound jacks such as Johnson Trailer Parts Dexter 12K Kit, and two-jack kits described as 24,000-pound systems. Johnson Trailer Parts Dexter 24K Kit pairs two 12,000-pound jacks and includes a flow divider for synchronized operation.
A lighter-duty application whose requirements suit a single jack may favor a single-jack kit; a buyer looking for paired lifting equipment may prefer the dual-kit format. Verify the trailer’s required capacity and the manufacturer’s instructions before treating a listed rating as suitable for your specific load.
Power setup and included controls
Look for a power arrangement that matches whether your trailer already has a hydraulic system. Johnson Trailer Parts Dexter 12K Kit includes a KTI double-acting pump, and Johnson Trailer Parts Dexter 24K Kit includes a KTI pump and flow divider. By contrast, Johnson Trailer Parts Dexter Add-On Kit is designed to connect to an existing power unit and includes a selector valve.
EQ Systems AJ 1/24 has a single-function pump and a manual override screw drive, while RAM PREMIUM HJ-15008 is self-contained and includes a corded remote. Buyers building a system around a supplied pump can favor the complete kits; someone integrating with existing hydraulics can consider the add-on.
Confirm the listed controls and connections suit the trailer before choosing.
Travel, mounting, and foot design
Match the jack’s travel and mounting style to the space and installation arrangement available on your trailer. Listed travel or stroke includes 24 inches for EQ Systems AJ 1/24 and the Chief 12K, and 24.2 inches for RAM PREMIUM HJ-Mounting descriptions differ: EQ Systems AJ 1/24 bolts to a gooseneck’s center tube; Primary Mover models include bolt-on or weld-on styles.
The Chief 12K has a 360-degree articulating foot, while RAM PREMIUM HJ-15008 has a pivoting large foot pad. Buyers with a compatible center-tube mounting location may favor the EQ design; those considering welding or a specialized foot should verify installation requirements and ground conditions.

Frequently Asked Questions
How do I determine the jack capacity my loaded gooseneck trailer needs?
Use the loaded trailer’s requirements and determine how much weight the jack or jacks must support in your setup. Compare that need with each product’s stated capacity, considering whether you are choosing a single- or dual-jack system. Confirm the required capacity with your trailer’s documentation or manufacturer before ordering.
Can a hydraulic jack kit connect to my trailer’s existing hydraulic power unit?
It may, but compatibility depends on your existing unit and the kit’s hydraulic and control requirements. The Dexter Add-On Kit is presented as an integration option for trailers that already have a hydraulic power unit. Verify connections, operating requirements, and compatibility with the manufacturer before buying; the supplied product details do not confirm universal fit.
Should a gooseneck trailer jack be bolted on or welded on?
Choose the mounting method that matches your trailer’s structure and the jack’s installation requirements. The listed options include bolt-on and weld-on designs, so do not assume they are interchangeable. Check the product instructions and trailer documentation, and confirm the mounting location and method before ordering or modifying the trailer.
When should I choose a dual-jack kit instead of a single-jack kit?
Choose a dual-jack kit when your trailer’s requirements call for two jacks operating together; the Dexter 24K Kit includes two 12,000-pound jacks and a flow divider for synchronized operation. A single-jack system may suit a setup requiring one jack. Verify the required capacity and configuration for your trailer before selecting either.
What does a manual override provide on a hydraulic trailer jack?
A manual override provides a non-powered operating option for the AJ 1/24, whose title specifies a manual override screw drive. The supplied details do not describe how to use it or when it is needed. Check the product instructions to understand its operation and confirm it suits your trailer and intended use.
Final Words
For a complete dual-jack system listed for gooseneck trailers, the Johnson Trailer Parts Dexter 24K Kit is the leading choice, with two 12,000-pound jacks, a KTI pump, and a flow divider. For a complete single-jack option, consider the Dexter 12K Kit. Existing hydraulic power units may point toward the add-on kit.
Before deciding, verify capacity, mounting compatibility, and hydraulic requirements against your trailer.
