Hook or Shackle?
Smart off roaders have known for years that the most secure way to use your recovery winch is replace the hook with a common screw pin shackle. Unless you are competing, the added seconds required to use a shackle versus a hook during a vehicle recovery is not worth the safety risk associated with standard winch hooks.
Factor 55 Methods
Factor 55 products are designed and manufactured using state of the art technologies. All of our products are designed using SolidWorks CAD systems and stress analyzed using COSMOS Finite Element Simulation software. The FEA results allow us to optimize a design concept by adding or removing material or changing material properties where necessary.Pro Link With Alloy Steel Pin!
Replace conventional winch hooks with the new safer, stronger, and smarter Factor 55 ProLink shackle mount.
Factor 55 introduces the new ProLink shackle mount for winch cables and synthetic ropes. Engineered and machined in the USA from lightweight billet 6061 aluminum, the ProLink provides a safe means to easily attach a standard 3/4" screw pin shackle to existing winch cable and rope eyes The cable or rope eye is captured into the body of the ProLink by a removable oversized 5/8" double shear pin. The front of the ProLink provides the precision shackle mounting hole and massive 1.2" thick mounting tab. The ProLink is compatible with both Hawse and Roller fairleads and snugs neatly against both versions.
The advantages of winching with a screw pin shackle over a conventional winch hook are many :
Screw pin shackles are up to 5X stronger than conventional winch hooks
Conventional hooks are too small to safely fit both ends of a recovery strap
Recover straps cannot slip out of a shackle like they can with hooks
Hook safety latches are not rated for loads and can tear recovery straps
Conventional hook surfaces add higher stresses to recovery strap fibers, resulting in decreased strap ratings
Shackles can be quickly removed and stowed away until needed for winching.
Hooks do not cinch neatly against fairleads and are prone to rattling and loosening
Conventional winch hooks are designed for chains – not commonly used recovery straps

The winch lock bolt is a custom 3/8-16 precision security bolt made from 1045 carbon alloy steel heat treated to Grade 5 yield strength. The key patterned head bolt is proprietary and the matching key is not available at your local retail hardware store. The winch lock bolt cannot be removed with ordinary screw drivers, pliers, or commonly sold security bits. Simply substitute one of your winch mounting bolts with the “Winch Lock” bolt and your winch is protected – simple!
