Hydraulic Jack For Horse Trailers

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, push-button lifting leg that bolts onto the front of a gooseneck or bumper-pull horse trailer in place of the old crank jack. The flagship single-leg model is the AJ Hydraulic Trailer Jack (SKU 8470UPS, $995.00), built around a 3.5″ x 3.5″ square tube-in-tube body with a 2″ cylinder bore. It delivers an 8,000 lb capacity and a full 24-inch stroke, retracting to 35.5″ and extending to 59.5″ so it clears even uneven campground ground. For heavier rigs there are dual-leg systems like the AJ 2/24 (8414AM, 16,000 lbs, $1,795.00) and the AM 2/24 w/Manual Override Hand Pump (8176AMUPS, 24,000 lbs, $2,595.00).

How does the push-button system actually work?

The AJ jack pairs a commercial single-function hydraulic pump with a weatherproof single-switch gear control with key. Press the switch and the cylinder drives the leg down to lift the gooseneck and disengage the hitch in seconds, with no cranking. Wire harnesses are sheathed in PVC high-temperature nylon braid, and a steel pump cover protects the works from road grime and weather. A manual-override screw drive is built in, so if power is ever lost you can still raise or lower the trailer by hand.

What is it built from, and what ships in the box?
The jack is a welded steel tube-in-tube design where the outer tube shields the cylinder from lateral movement, mounted on universal brackets engineered to bolt to the center tube of a gooseneck. It is rated to support living-quarters trailers with a short wall up to 11 feet. Note that the unit does not come with hydraulic fluid or mounting bolts; bolt kits are sold separately online. An optional Solar Panel Kit for AJ Hydraulic Trailer Jacks ($146.48) keeps the battery topped off so the jack stays ready to lift even after weeks parked off-grid.

Who needs this jack?

Anyone who hauls horses to shows, trail rides, camping trips, or the vet and is tired of muscling a manual crank. Because the work is done by hydraulics, anyone who can press a button can disconnect a trailer, putting setup within reach of women, younger riders, and anyone without heavy upper-body strength. Installation is straightforward: unbolt the old manual jack and bolt the automatic unit in its place. EQ Systems backs owners with dedicated service techs and a nationwide dealer network.

How do you buy or get one installed?

Jacks are sold directly through the EQ Systems online store at eqsystems.us/shop, with separate single-leg, dual-leg, and bumper-pull categories for horse trailers. If you are unsure which capacity and stroke fit your rig, call the sales department and an EQ Systems Account Manager will help you match the system; the company also performs professional installation at its Cassopolis, Michigan facility, complete with electrical hookups and pet-friendly accommodations. Systems carry a one- or two-year warranty depending on model, and replacement parts are covered for the remainder of the original warranty or 90 days, whichever is longer.

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 introduced hydraulic jacks to the horse industry roughly twenty years ago. Horse trailer manufacturers have adopted them as factory equipment because they are dependable and easy to service. The parent brand's hydraulic experience dates back to the 1990s across RV, motorsport, and custom markets.
What happens if I lose power or my battery dies?
The AJ jack includes a built-in manual-override screw drive, so you can raise or lower the trailer by hand even if you lose electrical power. Higher-end dual-leg models like the AM 2/24 add a manual-override hand pump for the same fail-safe. This means you are never stranded if the battery runs low.
Is there a solar option to keep the jack powered?
Yes. EQ Systems sells a Solar Panel Kit for AJ Hydraulic Trailer Jacks at $146.48, plus a matching kit for AM jacks at the same price. The solar kit keeps the trailer battery charged so the jack stays ready to lift even after the trailer has been parked off-grid for weeks at a time.
How is the jack built and what materials are used?
The AJ is a welded steel tube-in-tube jack with a 3.5″ x 3.5″ square outer body that shields the cylinder from lateral movement. It uses a 2-inch hydraulic cylinder bore, wire harnesses sheathed in PVC high-temperature nylon braid, and a steel pump cover to protect the components from weather and road debris. Straight-leg models in the line are powder-coated for limited-ground-clearance applications.
What are the dimensions of the AJ jack?
The single-leg AJ jack retracts to 35.5 inches and extends to 59.5 inches, giving a full 24-inch stroke. The square body measures 3.5″ x 3.5″. This range is generous enough to level and disconnect on uneven campground or showground surfaces.
What size trailer is the single-leg AJ jack suited for?
The AJ single-leg jack is engineered to bolt to the center tube of a gooseneck trailer and is rated for living-quarters trailers with a short wall up to 11 feet. For larger or heavier living-quarters rigs, EQ Systems recommends stepping up to a dual-leg AJ or AM system for added capacity and stability.
Does the jack come with everything needed to install it?
The jack does not include hydraulic fluid or mounting bolts. Bolt kits are sold separately on the EQ Systems online store, and you will need to add the appropriate hydraulic fluid. Everything else, including the pump, weatherproof switch control, and universal mounting brackets, is part of the unit.
How hard is it to install on an existing trailer?
Installation is straightforward for anyone with basic trailer-jack knowledge: you unbolt the old manual jack and bolt the new automatic jack into its place using the universal mounting brackets. EQ Systems also offers professional installation at its Cassopolis, Michigan facility, which has electrical hookups and pet-friendly accommodations while you wait.
Who benefits most from a push-button hydraulic jack?
Anyone who hauls horses to shows, trail rides, camping, or vet visits and is tired of cranking a manual jack by hand. Because hydraulics do the lifting, anyone who can press a button can disconnect the trailer, making it accessible to women, younger riders, and people without heavy upper-body strength. It also speeds up setup, getting you to your horses faster at the destination.
How do I control the jack?
The AJ jack uses a weatherproof single-switch gear control with a key. You press the switch and the commercial single-function hydraulic pump drives the leg to lift, level, or disconnect the trailer in seconds. The key adds a measure of security against unauthorized operation.
What kind of maintenance does the system need?
The hydraulic system is economical and straightforward to maintain, with lubrication of the moving parts being the primary upkeep task. You should also keep the hydraulic fluid at the correct level and the battery charged, which the optional solar kit helps with. EQ Systems provides service documents and a nationwide dealer network for support.
What warranty does EQ Systems offer?
Systems carry a one-year or two-year warranty depending on the model, with specific terms detailed in each unit's operation manual. Replacement parts are covered for the remainder of the original warranty or 90 days, whichever is longer, with proof of repair and original purchase dates. Warranty repairs require authorization from the EQ Systems service department.
How do I order or get help choosing the right jack?
Jacks are sold directly through the EQ Systems online store at eqsystems.us/shop, organized into single-leg, dual-leg, and bumper-pull categories for horse trailers. If you are unsure which capacity and stroke fit your trailer, call the sales department toll-free at 1-800-846-9659 (local 574-264-3437) and an EQ Systems Account Manager will help you match the right system to your rig.
