#1 · Best Overall

1. Dexter 24,000 lb Kit

• Load Capacity: 24,000 lb
• Material: Steel
• Compatible with Vehicle Type: Trailer

Best for: Complete dual-jack dump setups.

Why it ranks #1: Explicitly listed for dump trailers, it pairs two 12,000-pound jacks with a double-acting KTI pump and flow divider for synchronized operation.

Two 12,000-pound jacks and a KTI double-acting pump give this Dexter kit a combined 24,000-pound lifting rating for dump, cargo, and gooseneck trailers. Its flow divider synchronizes the pair, helping distribute hydraulic flow evenly instead of leaving the jacks to operate independently.

The included KTI power unit is rated at 2 GPM and up to 3,200 PSI, with power-up and power-down operation for controlled raising and lowering. A flow divider sends fluid evenly to both jacks, supporting synchronized movement across the dual-jack arrangement. The kit also lists six 48-inch hoses and jack covers, giving buyers specified connection and protection components to plan around. Its two-jack format is suited to trailers needing paired lifting points.

Skip it if you only need one jack added to existing hydraulics; the Johnson Trailer Parts Dexter PJC-1-ADS-K is an add-on kit.

Choose this kit for dump-trailer owners seeking paired hydraulic jacks, synchronized flow, and an included power unit. Its dual-jack format and 140-pound listed weight make installation planning important, especially where a single-jack upgrade would suffice.

#2 · Highest Capacity

2. Primary Mover 24K Weld-On

• Load Capacity: 12000 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer

Best for: Heavy-load dual-jack weld-ons.

Why it ranks #2: Its two 12,000-pound jacks provide 24,000-pound stated lifting capability, making this weld-on kit a fit for heavier trailer applications.

Two 12,000-pound jacks provide this Primary Mover kit with a listed 24,000-pound lifting capability for heavy trailer applications. Double-acting hydraulic operation replaces manual cranking, while its weld-on configuration makes it a candidate for owners planning a permanent dual-jack installation rather than a bolt-on arrangement.

The pair of 12,000-pound jacks gives the kit its stated 24,000-pound capability, making the two-jack layout central to its load-handling proposition. Powered hydraulic lifting is described as quick and effortless, avoiding manual cranking. Its weld-on style points toward permanent mounting, so installation planning should account for trailer structure and placement. The listed dimensions are 36 x 12 x 12 inches and the weight is 140 pounds, useful figures for handling and space planning.

Skip it if you prefer bolt-on mounting; the Primary Mover PFJ-2? No, the Primary Mover PFJ-1-MB-ADS-K is listed as a bolt-on jack kit.

This fits trailer owners seeking a two-jack hydraulic setup with a 24,000-pound stated capability and permanent weld-on mounting. Account for the 140-pound listed weight and installation requirements before choosing it over a bolt-on configuration.

#3 · Best Uneven-Surface Foot

3. Chief 12K Hydraulic Jack

• Load Capacity: 12,000 lb
• Material: Steel
• Compatible with Vehicle Type: Trailer

Best for: Uneven-ground trailer support.

Why it ranks #3: The 12,000-pound jack has a 360-degree articulating foot for uneven surfaces, 24 inches of travel, and a 3,000-PSI operating rating.

A 360-degree articulating foot lets this Chief 12K jack support a trailer on uneven surfaces, a useful distinction for varied dump-trailer parking. It combines that foot with 24 inches of travel and a 12,000-pound lift-and-hold capacity, in a double-acting, bolt-on-ready configuration.

The articulating foot can adjust its orientation on uneven ground, while 24 inches of travel provides range for raising or lowering the trailer. Double-acting operation supports movement in both directions, and the 3,000-psi pressure rating defines its operating specification. Upgraded quad seals are intended to improve holding and reduce bypass. At 100 pounds, the jack is a substantial component to account for when handling and planning the installation.

Skip it if you need a dual-jack system; the Johnson Trailer Parts Dexter PJD-12-20-K kit includes two 12,000-pound jacks and a pump.

This suits a buyer wanting a single bolt-on-ready hydraulic jack and an articulating foot for uneven trailer parking. Consider its 100-pound weight when organizing installation, and match the 12,000-pound rating to the intended trailer load.

#4 · Best System Add-On

4. Dexter 12,000 lb Add-On

• Load Capacity: 12,000 lb
• Material: Steel
• Compatible with Vehicle Type: RVs, Trailers

Best for: Existing hydraulic system add-ons.

Why it ranks #4: Designed for dump trailers and existing hydraulic power units, this single 12,000-pound jack kit includes a selector valve and hoses.

A selector valve lets this Dexter single-jack kit connect into an existing hydraulic system, making it an add-on rather than a full power-unit replacement. Its 12,000-pound jack is specified for dump, cargo, and gooseneck trailers, with double-acting operation for powered raising and lowering.

The 2-by-20-inch cylinder pairs with a 12,000-pound lifting rating for a single-jack upgrade. A billet aluminum six-port selector valve manages flow between the jack and other hydraulic functions, supporting integration with an existing power unit. Four 48-inch hoses and eight straight adapter fittings are listed among the included components, giving buyers connection pieces to plan around. The central compatibility requirement is an existing hydraulic power unit; this kit is not presented as a complete powered system.

Skip it if you need a complete dual-jack power setup; the Johnson Trailer Parts Dexter PJD-12-20-K includes two jacks and a hydraulic power unit.

Choose this for a trailer owner adding one 12,000-pound jack to an existing hydraulic system, especially when selector-valve control is useful. It depends on an existing power unit, so it is not the complete-system choice.

5. Primary Mover 12K Bolt-On Kit

• Compatible with Vehicle Type: Trailer

Best for: Bolt-on single-jack installations.

Why it ranks #5: This 12,000-pound double-acting jack is specified as bolt-on and includes a standard add kit, suiting buyers who need that mounting style.

Bolt-on mounting distinguishes this 12,000-pound Primary Mover jack from its weld-on counterpart, giving owners a kit specified for a bolted installation. Double-acting hydraulics replace manual cranking, while a dual holding valve supports stability during operation for hitching and trailer positioning.

The 12,000-pound lifting capability suits buyers whose trailer requirements fall within that stated limit. Double-acting hydraulic operation provides powered movement without manual cranking, and the dual holding valve is intended to support stability during use. Its bolt-on style and listed standard adds kit components give installation planning a different path from welding. At 60 pounds and 36 x 12 x 12 inches, its weight and dimensions are relevant when preparing the mounting area.

Skip it if you need two jacks with a pump included; the Johnson Trailer Parts Dexter PJD-12-20-K kit lists both in its package.

This suits trailer owners who want a single powered jack and prefer a bolt-on configuration to welding. Keep the 12,000-pound rating and the listed 36 x 12 x 12-inch dimensions in view when assessing load and installation space.

6. Primary Mover 12K Bolt-On

• Load Capacity: 12,000 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer

Best for: Bolt-on jack with power unit.

Why it ranks #6: It offers 12,000-pound stated capacity, a bolt-on style, and a hydraulic power unit, useful when selecting a single-jack kit.

This Primary Mover kit combines a bolt-on 12,000-pound jack with a hydraulic power unit, providing a more complete single-jack package than a jack-only add-on. Double-acting operation and a dual holding valve address powered movement and stability during trailer lifting.

The 12,000-pound rating sets the lifting limit for the single-jack arrangement, while double-acting hydraulics provide powered raising and lowering instead of manual cranking. The title identifies a hydraulic power unit in the kit, so buyers can plan around a supplied power source rather than an existing HPU requirement. A dual holding valve is listed to support stability during operation. At 120 pounds and 36 x 12 x 12 inches, the full kit calls for handling and storage planning.

Skip it if you need two jacks and a synchronized system; the Johnson Trailer Parts Dexter PJD-12-20-K kit includes a pair and flow divider.

#7

7. Primary Mover 12K Weld-On Kit

• Load Capacity: 12,000 lb
• Material: Alloy Steel
• Compatible with Vehicle Type: Trailer

Best for: Weld-on single-jack setups.

Why it ranks #7: The 12,000-pound double-acting weld-on jack includes a bracket and dual holding valve, but the listing does not describe a power unit.

A 12,000-pound lift rating gives this Primary Mover jack capacity for substantial trailer loads, while its double-acting hydraulic operation replaces manual cranking with powered lifting. The weld-on configuration suits owners planning a permanent installation, and the included bracket is part of the kit for that mounting workflow.

The hydraulic system operates at the touch of a button, making trailer lifting less dependent on manual effort. Its dual holding valve supports stability during operation, a useful feature when positioning a trailer for hitching. The 12,000-pound capacity is the key limit to weigh against the trailer and intended load. At 60 pounds and 36 x 12 x 12 inches, the jack also calls for space and support in the planned installation area.

Skip it if you need bolt-on mounting; the Primary Mover PFJ-1-MB-ADS-K is listed as a bolt-on jack kit.

Choose this for a trailer owner seeking a powered, single-jack weld-on setup with a 12,000-pound rating and holding valve. Its permanent mounting style is the important boundary: plan for a weld-on installation rather than a bolt-on attachment.

8. Primary Mover 12K Weld-On

• Load Capacity: 1.2E+4 lb
• Material: steel
• Compatible with Vehicle Type: Trailer

Best for: Weld-on bracketed jack upgrades.

Why it ranks #8: This 12,000-pound double-acting weld-on jack includes a bracket; its listed details provide less system-integration information than the higher-ranked kits.

A 12,000-pound lifting rating and weld-on style make this Primary Mover jack a single-jack option for trailers needing permanent mounting. Its double-acting hydraulic system replaces manual cranking, and the dual holding valve supports stability during operation when positioning the trailer.

Powered hydraulic lifting is described as operating at the touch of a button, avoiding manual cranking during trailer setup. The dual holding valve is intended to provide stability while the jack is in use, a practical consideration when positioning for hitching. Its stated capacity is 12,000 pounds, and the included bracket supports the listed weld-on configuration. The 36 x 12 x 12-inch dimensions and 60-pound weight help owners plan for installation space and handling.

Skip it if you want bolt-on mounting; the Primary Mover PFJ-1-MB-ADS-K is listed in a bolt-on style.

This suits trailer owners wanting a powered, 12,000-pound single jack with a bracket for weld-on installation. Choose it when permanent mounting fits the plan; its weld-on style is the boundary for buyers seeking bolt-on hardware.

#9

9. Generic 7,000 lb Replacement Jack

• Load Capacity: 7000 lb
• Compatible with Vehicle Type: Trailer

Best for: Seven-thousand-pound replacement fit.

Why it ranks #9: It is described for dump utility trailers and offers a 16-inch stroke, but it has no pump and lower stated capacity than the kits.

A 16-inch stroke and removable foot give this 7,000-pound hydraulic jack a defined replacement profile for Stillwell dump, utility, and horse trailers. Its listed 24-inch retracted and 40-inch extended lengths help buyers assess the jack’s operating range against their trailer’s existing setup.

The 16-inch stroke describes the travel between the listed 24-inch retracted and 40-inch extended lengths, helping owners assess whether its range suits their lifting needs. The removable foot offers a changeable contact point for setup and storage. The title explicitly identifies this as a jack without a pump, so it is a component for a hydraulic arrangement rather than a self-contained powered kit. Check the stated 7,000-pound capacity against the intended trailer load.

Skip it if you need an included dual-jack power system; the Johnson Trailer Parts Dexter PJD-12-20-K kit includes two jacks and a pump.

This is for owners replacing a jack on a compatible Stillwell dump, utility, or horse trailer who need its 16-inch stroke and removable foot. It is not a complete powered kit; a pump is not included.

#10

10. Tritala 7,000 lb Replacement Jack

• Load Capacity: 6000 lb
• Material: Steel
• Compatible with Vehicle Type: Bus

Best for: Stillwell jack replacements.

Why it ranks #10: The replacement is described for dump utility trailers, but its specifications state 6,000 pounds rather than the 7,000-pound title figure.

A 16-inch stroke and removable foot define this Tritala replacement jack for Stillwell dump, utility, and horse trailers. Its title gives 24-inch retracted and 40-inch extended lengths, letting owners compare its reach with their current setup before planning a replacement.

The listed 16-inch stroke spans the specified 24-inch retracted and 40-inch extended lengths, giving buyers practical dimensions to compare with an existing jack. A removable foot provides a detachable contact point, while the title identifies the unit as a replacement jack without a pump. The capacity information needs particular attention: the title says 7,000 pounds, but the specification lists 6,000 pounds. Treat the lower specification as the stated limit when assessing loads.

Skip it if you need a pump included; the Johnson Trailer Parts Dexter PJD-12-20-K kit lists a hydraulic power unit and two jacks.

This suits a buyer replacing a Stillwell jack who can use the stated dimensions and removable foot. Resolve the 6,000-versus-7,000-pound capacity discrepancy before choosing it, and account for the fact that no pump is included.
