Factor 55 00250-01 Ultrahook Winch Hook Closed System Shackle – 16,000 lb Load / 48,000 lb Pin Mount – Red

Ultrahook: The Smart Choice for Closed-Loop Winching

The Factor 55 Ultrahook 00250-01 combines a compact winch hook with an industry-leading closed system shackle mount. This design places a latch pin inside the hook body, which can lock into place to create a true Closed Loop System. The result is a streamlined, low-profile accessory that aims to improve control during recovery and reduce rattle when loaded.

Designed for off-road explorers and demanding field use, Ultrahook emphasizes practical, user-centric features. Integrated EPDM rubber pads cushion the connection against the fairlead and help keep the hook aligned during pull, while the ergonomic finger grips encourage proper hook-up orientation. This combination supports a tidy, secure setup without adding unnecessary weight.

Key Benefits at a Glance

• Closed system design with a built-in latch lock pin for a secure, repeatable connection
• EPDM rubber pads protect the fairlead and help minimize rattling and metal-to-metal contact
• Low-profile, CNC-machined 7000-series aluminum keeps weight down while preserving strength

Strength, Specs, and Versatility

Ultrahook is engineered for high-load scenarios while remaining practical to carry and fit in a vehicle kit. Notable specs include a maximum load of 16,000 lbs, a throat opening rated at up to 31,000 lbs of ultimate strength, and a shackle pin mount capable of 48,000 lbs. The unit accepts line diameters up to 3/8" and folds flat to about 3" thick when stored. A 5/8" aerospace-grade titanium double-shear pin is included for a robust, secure pin connection. The combination of materials and design enables use with both steel and synthetic winch rope, and without rope splicing in typical setups.

• Maximum load: 16,000 lbs; shackle pin mount: 48,000 lbs
• Ultimate throat strength: 31,000 lbs; weight: ~32 oz
• Made from CNC-machined 7000-series aluminum, engineered for reliability

Simple Installation, Flexible Use

Installation is straightforward thanks to a hole machined into the hook’s body that accepts standard shackles or soft shackles up to 1/2". The Ultrahook can function as a traditional hook or be used as a shackle mount, and it is compatible with both steel and synthetic winch rope. The design eliminates the need for rope splicing in most configurations, thanks to its double-shear pin design that accommodates rope or cable eyes.

In short, the Ultrahook aims to offer a practical, reliable option for off-road recovery scenarios. It emphasizes secure connections, protection of moving parts, and versatile mounting options, all while keeping weight manageable and installation quick. If you value a clean, closed-loop setup with thoughtful details, Ultrahook may suit your needs as a potential addition to your recovery toolbox.
