Square tube-in-tube dual leg hydraulic jack system for the front of Gooseneck trailers. 16,000 lb total capacity. 24" stroke. Single-switch tandem operation. Commercial pump with manual override screw drive. Weatherproof keyed switch. Wireless remote compatible.
The EQ Systems 8414AMUPS is a complete dual-leg hydraulic jack system purpose-built to bolt to the front of Gooseneck trailers. Two 3.5" × 3.5" square tube-in-tube hydraulic jacks operate in tandem from a single switch, lifting and lowering both legs simultaneously so you can raise or drop the front of your trailer in seconds — no manual cranking, no uneven loading on one side.
The system is built around a commercial single-function pump with a screw-drive manual override, giving you a reliable fallback in the event of a power or pump issue. The weatherproof keyed switch keeps operation secure and protected from the elements, and all wire harnesses are wrapped in PVC high-temperature nylon braid to hold up in harsh outdoor and trailer environments. A steel pump cover protects the hydraulic pump assembly, and universal mounting brackets are included for straightforward installation. For added convenience, the 8414AMUPS is also compatible with EQ Systems' optional wireless remote (part #7823, sold separately), allowing you to operate the jacks from outside the cab or trailer.
8,000 lbs per jack — commercial-grade hydraulic lifting power for heavy Gooseneck trailers and equipment
3.5" × 3.5" square tube-in-tube construction provides superior rigidity and resistance to side-load flex versus round-tube designs
Single weatherproof gear switch with key operates both jacks in tandem — keeps unauthorized use locked out in any conditions
Works with EQ Systems wireless remote (part #7823, sold separately) for convenient operation away from the switch panel
EQ Systems offers two families of hydraulic trailer jack systems. Here's how they differ: AJ Series (This Unit) Square tube-in-tube design — more rigid lateral construction Designed for Gooseneck trailer front mounting Available in single leg and dual leg configurations Wireless remote compatible AM Series Round tube hydraulic jack design Available in single and dual leg configurations across various stroke lengths Also designed for trailer front applications Both series use Dexron ATF hydraulic fluid, include manual overrides, and are built for heavy-duty trailer use. Contact EQ Systems or our team if you need help choosing between series for your specific trailer application.
The following items are not included with the 8414AMUPS and must be sourced separately before installation or use: • Hydraulic Fluid: Use Dexron ATF — fill reservoir to approximately 1–1.5" from top after installation • Mounting Bolts: Hardware for securing the universal mounting brackets to your trailer frame — select appropriate grade and length for your trailer's frame material and thickness EQ Systems recommends using the AM Bolt Kit (part #7227) — contact EQ Systems for bolt kit availability and compatibility with this system.
