Equalizr Sys Trailer Jacks: Hydraulic Power for Every Tow

When it comes to raising and lowering a loaded trailer, the difference between a manual hand-crank jack and an Equalizr Sys (EQ Systems) hydraulic trailer jack is night and day. Trailer jacks are a critical piece of towing hardware, and EQ Systems has spent decades engineering solutions that take the grunt work out of hitching and unhitching — whether you're hauling horses, motorsports equipment, or heavy commercial loads.

A Legacy Built on Hydraulic Innovation

EQ Systems, operating under the brand name Equalizr Sys, was among the first to bring hydraulic jack technology to the trailer industry. Over twenty years ago, Equalizer introduced hydraulic jacks to the horse industry, and the technology has since expanded across motorsports, RV, and commercial towing applications. Today, over 70% of horse trailer manufacturers equip their trailers with EQ Systems jacks, and service and parts are easy to get through the largest trailer dealer network.

What Sets Equalizr Sys Trailer Jacks Apart

The engineering philosophy behind every Equalizr Sys trailer jack centers on reliability, safety, and ease of use. Several features consistently set these jacks apart from the competition:

• Built-in Manual Override: Every EQ jack comes with a backup hand pump or manual override, so you're never stranded even if your power source fails.
• Smooth Hydraulic Operation: The smooth, quiet hydraulic operation makes raising and lowering a trailer far faster than any manual crank alternative.
• Weather-Resistant Construction: High-temperature nylon braid wire harnesses and a steel pump cover stand up to rain, mud, and dust.
• Transparent Fluid Monitoring: The oil reservoir allows you to see the oil level just like your truck's radiator fluid and power steering tanks, simplifying routine maintenance checks.
• Flexible Power Options: You can use 12 volts from your truck or the onboard battery on the trailer, giving you versatile power configurations for nearly any setup.
• American Made: Designed and manufactured in Michigan, EQ Systems delivers quality you can trust for years of reliable service.

Product Lines & Configurations

Equalizr Sys offers a range of trailer jack configurations to suit different trailer types and load requirements. The flagship AM Series single-leg hydraulic jack — such as the model 8222FUPS — is a popular choice for tongue jacks. The AM Series delivers a lifting capacity of 12,000 lbs., comes standard with a hand pump manual override, and features a 4" x 4" outer tube with a 24" stroke. The harness wire is braided with durable PVC-coated nylon, and universal mounting brackets are included to allow installation in place of most square-leg hand crank jacks.

For lighter-duty applications, the AJ70 Series provides a capable entry point: the AJ70 Series single-leg hydraulic trailer jack has a lifting capacity of 7,500 lbs. and comes standard with a screw-style manual override. For those needing maximum capacity, EQ Systems offers both single-leg and dual-leg options to match your trailer's needs. Four and six-point automatic leveling systems are also available for trailers where precision leveling is a priority.

Replacement and maintenance parts — including jack boxes (such as the 7222FUPS), leveling jack cylinders, foot pads like the 7849 octagon foot pad, and jack motors — round out the Equalizr Sys catalog so owners can keep their existing systems running at peak performance. EQ Systems, a division of EQ United, uses advanced technology and high-quality steel to deliver top-notch performance for the RV and trailer industries.
