Upgrade the standard winch hook with a replacement that enhances reliability, performance, and provides closed system winching. Choose from ProLink, FlatLink, UltraHook, and more for just about any truck, Jeep, or SUV.
Factor 55 offers three families of winch line shackle mounts for truck, Jeep and SUV applications. Some have variations for different options and uses.
The ProLink is Factor 55’s original shackle mount. Trusted and used by first responders worldwide, ProLink is easy to install and allows winch owners the ability to replace the vehicle’s winch hook with a stronger shackle/D-Ring mount.
FlatLink is Factor 55’s original folding winch shackle bracket. Features include a precision shackle mounting hole and a folding design giving you a lower profile, and allowing for a better approach angle than ProLink.
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 and installs in minutes. 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 matter what color your truck, Jeep, or SUV is, Factor 55 offers a host of great colors to match, accent, or contrast your rig’s paint. All are made from top-quality CNC machined aluminum components, have EPMD rubber guards to prevent rattling, and are made in the USA.
Closed System Winching™ is a technique that uses rigging comprised entirely of closed-link hardware. The result is the most secure and reliable winch rigging available.
In Closed System Winching, the traditional hook is upgraded to a patented Factor 55 ProLink®, FlatLink®, or UltraHook® winch line shackle mount. When combined with a shackle, you’ll have an attachment that will contain loads even during momentary slack conditions where winch loads may shift. With Closed System Winching you get the extra security and confidence needed to tackle the most demanding winch recoveries.
