If you're hauling horses you need the EQ Systems Hydraulic Jack which makes lifting, leveling and disconnecting from your trailer a breeze!

So Just Who Needs The EQ Systems Hydraulic Jack For Horse Trailers?

If you are a horse person who hauls their horses to shows, or out for trail rides, or camping or trips to the vet… you need the EQ Systems to help you disconnect from your horse trailer! Nobody wants to spend a lot of time manually cranking their trailer on and off the truck, not when you have the option of just simply pushing a button! Spend less time cranking and more time riding— and you’ll start to enjoy hauling your horses as never before!


What sets EQ Systems Apart From Other Hydraulic Lifting Systems?

What sets us apart from our competitors is the focus on the little things, such as weather proof connectors, nylon braided harness as opposed to plastic auto loom. Even the options available to make the customers installation easier from mounting brackets designed to fit specific horse trailer manufacturers to the industry exclusive hand pump override insuring you are not stuck because of a dead or low battery. Perhaps the most important thing that sets EQ Systems apart from our competitors is the service you receive after the fact. EQ Systems has a dedicated service tech staff to help if any issues do arise, and a network of dealers across the nation available.


Is It Easy For Women To Use?

EQ Systems introduced hydraulic jacks to the horse trailer industry knowing that a large percentage of the end users are women. Now instead of having to manually crank the trailer off or on the hitch, within seconds you can have the trailer off or on with just pushing a button. You’ll love the freedom and the stress relief— you’ll be unloading your horses, while your friends are still jumping up and down on their hitch trying to disconnect!


What Does It Take To Install?

Depending on how the manual jacks are mounted, installation should only take 2-4 hours and then you can enjoy it for many stress free years to come! In a lot of cases it is as easy as unbolting the manual jacks on the trailer, and bolting the new hydraulic jacks in their place. Then it is a matter of hooking up the hoses from the pump to the legs, running the wires to the battery and running the system several times to purge, or get all the air out of it.


How Do I Know If I Need The “Single” or the “Dual" What is the difference?

The general rule of thumb for determining if you need a dual or single leg system, is based on what manual system was on the trailer. A single leg system is going to be used for the basic purpose of lifting and lowering the trailer off and onto the ball in your truck. With the dual leg system, the main purpose is also the lifting and lowering, but it also provides a more stability at the front of the trailer since each leg is mounted towards the ends of the front wall as opposed to the center of the front wall like the single leg system. Don’t worry, just talk to us by phone and we’ll make sure you have the right system for you!!

What Advantages Do The Auto Level Option Offer To Horse Owners?

For the horse trailer owner who wants all the bells and whistles, EQ Systems offers both a 4 point and 6 point auto level system. Just because you have to park out in an uneven field, that does not mean your trailer has to be unlevel. With just a touch of a button the EQ Systems Auto Level system will have your trailer level and stabilized.

What Do These Systems Cost?

Remember, if you have a horse business, this equipment is tax deductible! Our systems start from an affordable $895 up to $1655—with several prices in between... depending on which system you decide upon. The EQ System can make all the difference in stress, and comfort to both you and the horses you are hauling.

So What Do Horse Owners Say About Their Equalizer Systems?

I had an electric system on this trailer before and it would take ages to get the trailer on or off the truck. Life's a timed event - might as well make this part quick so I can get to the shooting arena sooner! - Work smarter, not harder! Loving my EQ Systems Hydraulic jack!!

What exactly is the EQ Systems Hydraulic Jack?

It is a powered, button-operated hydraulic lifting jack that bolts onto your horse trailer in place of the manual crank jack you fight with today. A single push of a weatherproof switch raises, lowers, and levels the trailer so you can hitch or disconnect from your truck in seconds. EQ Systems builds these in single-leg, dual-leg, and bumper-pull configurations, with hydraulic four- and six-point automatic leveling systems available for larger living-quarters rigs.

Who builds it and where do you reach them?

EQ Systems is headquartered at 19300 Grange St, Cassopolis, MI 49031, and their hydraulic lifting and leveling products are designed and manufactured in Michigan. You can reach the company toll-free at or locally. They also support a nationwide dealer network plus dedicated customer service for installation and troubleshooting questions.

How the hydraulic system actually lifts your trailer.
A commercial single-function hydraulic pump drives the cylinder, and you control it through a weatherproof single-switch gear control with a key. The wire harnesses use a PVC high-temperature nylon braid for durability, and a steel pump cover protects the electronics from the elements. Each unit includes a manual-override screw drive (or hand-pump option on AM models) so you can still raise the trailer if power is ever lost, and the pump runs off your trailer battery.

Capacities, stroke, and the construction that holds your rig.
The flagship AJ Hydraulic Trailer Jack 1/24 (SKU 8470UPS) lifts 8,000 lbs per jack with a 24-inch stroke, a 2-inch cylinder bore, and a square tube-in-tube single-leg body built from 3.5" x 3.5" steel, measuring 35.5 inches retracted and 59.5 inches extended. It is rated for living-quarters trailers up to 11-foot short walls and bolts to the center tube of gooseneck trailers. Heavier AM jacks step up to 12,000 lbs single-leg and 24,000 lbs dual-leg, and the broader straight-leg and tube-in-tube line spans 7,500 lbs all the way to 40,000 lbs.

Why button operation changes who can hitch a trailer.
Hand-cranking a loaded gooseneck takes real arm strength, which is exactly the barrier EQ Systems set out to remove. With the push-button system, anyone who can press a button, including women and younger riders, can disconnect a horse trailer safely and on their own. It slashes setup time before a show, trail ride, camping trip, or vet run, and the low-maintenance design mainly asks that you keep the moving parts lubricated.

How to buy and what it costs.
EQ Systems sells direct through eqsystems.us/shop, with horse-trailer jacks listed by configuration. Single-leg pricing starts at $965.00 for the AJ 1/20 and $995.00 for the AJ 1/24, climbing to $1,295.00–$1,595.00 for the 12,000-lb AM models. Dual-leg systems run $1,795.00 to $2,595.00, and the 6,000-lb Hydraulic Bumper Pull TJ is $795.00; note the jacks do not include hydraulic fluid or mounting bolts (bolt kits sold separately), and solar panel kits are available for $146.48.

The Solution Section (FAQ)
Who needs a hydraulic jack for their horse trailer?

The EQ Systems Hydraulic Jack is for horse owners who haul their horses to shows, trail rides, camping, or vet trips. It replaces the manual cranking required to disconnect a trailer from a tow vehicle — push a button instead of cranking.

What sets EQ Systems apart from other trailer-jack manufacturers?

EQ Systems cites weather-proof connectors, nylon-braided harness instead of plastic auto loom, mounting brackets designed to fit specific horse-trailer manufacturers, and an industry-exclusive hand-pump override in case of a dead or low battery. Their stated focus is "on the little things."

What happens if my trailer's battery dies — am I stranded?

No — EQ Systems' industry-exclusive hand-pump override lets you operate the jack manually if the battery is low or dead. The override is part of the standard design, not an optional add-on.

Does EQ Systems offer support after the sale?

Yes — the company highlights after-sale service as part of what sets them apart. They have a dedicated service-tech staff plus a network of dealers across the nation available for support if issues arise.

Will EQ Systems mounting brackets fit my specific trailer brand?

EQ Systems offers mounting brackets designed to fit specific horse-trailer manufacturers, making installation easier than a generic universal mount. Check with their service team about your trailer brand before ordering.

What is the EQ Systems Hydraulic Jack for horse trailers?
It is a powered, button-operated hydraulic jack that replaces the manual crank jack on your horse trailer. With one push of a weatherproof key switch it raises, lowers, and levels the trailer so you can hitch or disconnect from your truck in seconds. EQ Systems offers it in single-leg, dual-leg, and bumper-pull versions.
How much weight can the EQ Systems jack lift?
The popular AJ models lift 8,000 lbs per jack, while the heavier-duty AM models handle 12,000 lbs in single-leg form and up to 24,000 lbs in dual-leg form. Across the full straight-leg and tube-in-tube product line, capacities range from 7,500 lbs all the way up to 40,000 lbs. The Hydraulic Bumper Pull TJ is rated at 6,000 lbs.
What is the stroke length and size of the AJ 1/24 jack?
The AJ Hydraulic Trailer Jack 1/24 (SKU 8470UPS) has a 24-inch stroke and a 2-inch cylinder bore. Its square tube-in-tube single-leg body is built from 3.5" x 3.5" steel, measuring 35.5 inches retracted and 59.5 inches extended. It is designed for trailers with living quarters up to 11-foot short walls.
How does the hydraulic jack work?
A commercial single-function hydraulic pump drives the cylinder, and you operate it with a weatherproof single-switch gear control that uses a key. Pressing the button raises or lowers the trailer with no manual cranking. The pump runs off your trailer's battery, and the wire harnesses are protected with a PVC high-temperature nylon braid.
What happens if the battery dies or I lose power?
Every horse-trailer jack includes a manual override so you are never stranded. The AJ models use a manual-override screw drive, while the AM models offer a manual-override hand-pump option. This lets you still raise or lower the trailer mechanically if electrical power is unavailable.
Who makes EQ Systems jacks and where are they manufactured?
EQ Systems is based at 19300 Grange St, Cassopolis, MI 49031, and their hydraulic lifting and leveling products are designed and manufactured in Michigan. The company has decades of experience supplying hydraulic systems for RVs, horse trailers, motorsports trailers, and commercial applications.
How much does the EQ Systems Hydraulic Jack cost?
Single-leg pricing starts at $965.00 for the AJ 1/20 and $995.00 for the AJ 1/24, with the 12,000-lb AM single-leg models at $1,295.00 to $1,595.00. Dual-leg systems run from $1,795.00 up to $2,595.00, and the 6,000-lb Hydraulic Bumper Pull TJ is $795.00. Prices are listed on the EQ Systems online shop.
Where can I buy an EQ Systems hydraulic jack?
You can buy directly through the EQ Systems online store at eqsystems.us/shop, where horse-trailer jacks are organized by single-leg, dual-leg, and bumper-pull categories. EQ Systems also supports a nationwide dealer network. To find a dealer or ask questions, call toll-free 1-800-846-9659 or local 574-264-3437.
Is the jack hard to install on my existing trailer?
No. According to EQ Systems, basic trailer-jack knowledge is enough for most installs. The process involves unbolting your manual jack, mounting the new automatic unit, connecting the hoses from the pump to the legs, and running wires to the battery. Universal mounting brackets are included with the AJ jack.
Does the jack include hydraulic fluid and mounting bolts?
No. The AJ Hydraulic Trailer Jack does not include hydraulic fluid or bolts. Bolt kits are available separately, and you will need to add the appropriate hydraulic fluid. Universal mounting brackets are included with the jack itself.
What is the difference between single-leg and dual-leg jacks?
A single-leg jack uses one hydraulic leg to lift and level the trailer, which is typical for many gooseneck horse trailers. Dual-leg systems use two coordinated legs for heavier rigs and greater stability, with capacities up to 24,000 lbs on the AM 2/24. EQ Systems also offers a two-function manual selector on certain dual-leg models.
What is a tube-in-tube jack versus a straight-leg jack?
Tube-in-tube jacks have an outer tube that protects the inner cylinder from lateral movement and include a heavy-duty swivel foot pad, making them ideal for heavy-duty horse, livestock, and gooseneck trailers. Straight-leg jacks are powder-coated and lightweight, well suited where ground clearance is limited. Both can be ordered for weld-on or bolt-on installation.
Can someone without much upper-body strength operate this jack?
Yes, and that is one of its main advantages. Hand-cranking a loaded gooseneck trailer takes significant arm strength, but the button-activated EQ Systems system means anyone who can press a button, including women and younger riders, can disconnect a horse trailer on their own. It makes hitching safer and far less physically demanding.
Is the EQ Systems jack hard to maintain?
No, the hydraulic system is economical and low-maintenance. The primary requirement is keeping the moving parts lubricated. A steel pump cover protects the components and the harnesses use a high-temperature PVC nylon braid, so the system is built to hold up to weather and regular use.
What kind of trailers is the AJ jack designed for?
The AJ Hydraulic Trailer Jack is built for heavy-duty applications including horse trailers, livestock trailers, and gooseneck trailers. The 1/24 model suits living-quarters trailers up to 11-foot short walls and bolts to the center tube of a gooseneck trailer. EQ Systems also makes versions for bumper-pull and motorsports trailers.
Are there solar or power accessories for the jack?
Yes. EQ Systems offers a Solar Panel Kit for AJ Hydraulic Trailer Jacks and a Solar Panel Kit for AM Hydraulic Trailer Jacks, each priced at $146.48. These help keep the trailer battery charged so your hydraulic jack always has power when you need to hitch or disconnect.
Does EQ Systems offer automatic leveling for living-quarters trailers?
Yes. Beyond the lifting jacks, EQ Systems offers hydraulic four-point and six-point automatic leveling systems for trailers. These let you set up a horse trailer with living quarters quickly and safely on uneven ground, leveling at the push of a button rather than chasing the bubble with blocks and a manual jack.
