Factor 55 Winch Hook

Factor 55 Winch Hooks: Engineering That Raises the Bar on Recovery Safety

When it comes to winch hooks, few brands have challenged the status quo as boldly as Factor 55. Rather than simply improving on the traditional open hook design, Factor 55 took a fundamentally different approach — pioneering Closed System Winching®, a recovery technique that replaces conventional hooks with precision-engineered shackle mounts that keep every connection in the recovery system fully closed and secure. The result is a lineup of winch hooks that are trusted by off-road enthusiasts, competitive racers, and even military users.

The UltraHook: The Best of Both Worlds

The flagship of Factor 55's winch hook lineup is the UltraHook. Originally developed to meet the needs of off-road racers who wanted the speed of a hook and functionality of closed system winching, the low-profile UltraHook features an industry-first closed system shackle mount hole machined into the body of the hook. A latch pin, which is stored in the hook's body, can lock the safety latch securely into place for a true Closed Loop System™.

No rope splicing is required — the double shear pin design accepts rope and cable eyes, and is compatible with either steel or synthetic winch rope. The UltraHook includes a 5/8" diameter aerospace-grade 6AI-4V Grade V titanium double shear pin, with a maximum load rating of 16,000 lbs and an ultimate strength of 48,000 lbs at the shackle pin mount. UltraHook is the first winch hook that can be stored neatly against a winch's fairlead, protecting it from a metal-to-metal connection, thanks to EPDM rubber pads which also eliminate rattling. For powersports vehicles, the UltraHook XTV brings these same innovations to ATV and UTV platforms. With eight colors to choose from, you can also match your UltraHook to your ATV or UTV.

The FlatLink Family: Low-Profile, High-Strength

For those seeking an ultra-compact profile, the FlatLink series offers a foldable shackle mount solution. The FlatLink E replaces the conventional winch hook with a stronger shackle/D-Ring mount and folds neatly into the fairlead when not in use. It attaches with a super-strong aerospace-grade double-shear titanium pin and snap ring, which is easily installed in minutes. The large pear-shaped shackle mounting hole allows for attachment to either the pin or bow end of common screw pin shackles, as well as common OEM recovery points.

For off-camber and bridle recovery situations, the FlatLink MultiMount steps up with a specialized design. The FlatLink MultiMount is designed for difficult off-camber vehicle recovery scenarios where two different winch pull directions are often necessary. With a max load of 16,000 lbs capacity and an ultimate load of 40,000 lbs, Factor 55 has most any vehicle covered on the trail.

Built in the USA, Engineered to Survive

Factor 55 winch hook products feature top-tier components, such as a titanium shear pin, precision CNC-milled military grade aluminum, and EPDM rubber pads to protect against rattling. All Factor 55 products are designed in-house using the latest 3D CAD software and optimized using Cosmos FEA (Finite Element Analysis), with destructive testing performed on each design prior to public release. Trusted by off-roaders, racers, and even the military, Factor 55 winch line shackle mounts help you become "equipped to explore."

All Factor 55 shackle mounts, including XTV models for powersports vehicles, can be used with either steel or synthetic rope. Many Factor 55 winch line shackle mounts are available in a variety of colors to complement any vehicle build. Whether you wheel a truck, Jeep, SUV, ATV, or UTV, Factor 55's winch hook lineup is one of the most thoroughly engineered — and thoroughly tested — options on the market.
