Key Features

24,000-Pound Lifting Capability
Equipped with two 12,000-pound jacks, this system lifts heavy trailers and equipment with ease and precision. Built for commercial-grade applications, it gives you the confidence to tackle the toughest loads.

Dual Counterbalance Valves
Each jack features integrated counterbalance valves that act as hydraulic locks—preventing jack drift during transit and ensuring complete stability in both the extended and retracted positions.

Primary Mover Double-Acting Hydraulic Power Unit
The system includes our trusted Primary Mover double-acting power unit, delivering consistent power with a 2-button remote pendant. Relief settings are calibrated to approx. 3200 PSI on the extend port and 1500 PSI on the retract port for reliable operation.

Hydraulic Flow Divider
Ensures both jacks operate in unison by automatically redirecting fluid to the slower jack, leveling pressure and lift height on both sides. This feature improves safety and keeps your trailer level during operation.

15-Foot Remote Pendant
Control your jacks from a safe distance with the included 15-foot pendant, giving you flexibility and full control during setup and breakdown.

Zinc-Plated Inner Sleeves and Foot
Built to last in harsh conditions, the zinc-coated jack internals resist corrosion, moisture, and road grime.

Heavy-Duty Build with Grade 8 Hardware
All mounting hardware is Grade 8 for maximum strength and durability under demanding loads and rough environments.

Bolt-On or Weld-On Mounting Options
Offered in both bolt-on and weld-on configurations to suit your trailer build.
🔧 For bolt-on applications, please verify compatibility by reviewing the mounting pattern dimensions in the product photos and documentation.

Complete Kit, Easy Installation
Everything you need is included—hoses, fittings, cables, and clear instructions. Get your system up and running quickly with a user-friendly design.
