12,000 lb Bolt-On Hydraulic Trailer Jack Kit with Power Unit
Product Description
Upgrade your trailer with a complete powered hydraulic jack system designed for heavy-duty lifting and convenient operation.
The 12,000 lb Bolt-On Hydraulic Trailer Jack Kit with Power Unit combines a heavy-duty bolt-on hydraulic trailer jack with a 1.6KW, 4L Double-Acting Hydraulic Power Unit, providing powered extension and retraction without requiring the jack to share an existing trailer hydraulic circuit.
The hydraulic jack features a rugged approximately 4" square body, integrated hydraulic cylinder, and load-holding system for reliable lifting and stable support.
A 15FT wired controller allows convenient remote operation, while the included two 6FT hydraulic hoses, hydraulic fittings, and 2FT 4AWG power cable provide the essential hydraulic and electrical components for installation.
The bolt-on mounting design also makes future removal, servicing, and replacement more convenient compared with permanently welded jack systems.

Double-Acting Hydraulic Power Unit
The included 1.6KW Double-Acting Hydraulic Power Unit provides powered operation in both directions.
Power Up
Hydraulic pressure extends the jack to raise and support the trailer.
Power Down
Hydraulic pressure retracts the jack, eliminating the need to rely solely on gravity for retraction.
This powered extension and retraction provides convenient operation for trailers that are frequently connected, disconnected, loaded, or repositioned.
15FT Wired Controller
The included 15FT wired pendant controller allows the operator to control jack extension and retraction from a convenient working position.
The extended controller cable provides greater flexibility when positioning yourself around the trailer during operation.
Integrated Load-Holding System
The hydraulic jack incorporates a load-holding system designed to help maintain jack position while supporting a load.
This provides dependable support during common trailer operations such as:
- Hitching
- Unhitching
- Loading
- Unloading
- Trailer positioning
- Trailer setup
Bolt-On Mounting Design
The bolt-on mounting configuration provides a practical alternative to permanently welded hydraulic trailer jacks.
Benefits
- Easier installation
- Easier removal
- Convenient servicing
- Easier replacement
- No need to permanently weld the jack body directly to the trailer
- Suitable for compatible heavy-duty trailer frames
Always verify trailer frame strength and mounting dimensions before installation.
