Factor 55 Ultrahook 00250-04 Closed-System Winch Hook – 16,000 lb Load | Shackle Mount | 48,000 lb Ultimate Strength

Overview

Meet the Factor 55 Ultrahook 00250-04, a purpose-built winch hook that blends speed with the safety of a closed-loop system. Designed for off-road racers and adventure vehicles, it installs quickly thanks to a machined hook body with an integrated shackle mount hole. A latch pin stored inside the hook securely locks the safety latch, delivering a true closed loop when used with compatible rigging.

Why a closed system matters

Traditional hooks with non-closable openings can allow loads to shift under momentary slack, risking disengagement. The Ultrahook embraces a dedicated closed-system approach, pairing with closed-link hardware to help keep rigging secure during demanding recoveries. This design aims to reduce metal-to-metal contact and stray play that can occur in tougher conditions.

Ease of installation and usage

Real-world applications and benefits

In field recoveries, the Ultrahook can help keep rigging organized with a neater appearance against the winch drum, while the rubber pads reduce wear on the fairlead. The combination of a precise grip, protective pads, and a sturdy pin system may contribute to smoother, more controlled pulls in challenging terrain.
