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 Factor ProLink is compatible with both Hawse and Roller fairleads and snugs neatly against both versions.

Standard Features:

♦ Screw pin shackles are up to 5X stronger than conventional winch hooks;
♦ Recover straps cannot slip out of a shackle like they can with hooks;
♦ 16,000 pound max load rating;
♦ Fits all steel cables and synthetic ropes up to 3/8″ in diameter;
♦ Fits eyes equipped with standard or tube thimbles to 3/8 inch diameters;
♦ Can be installed and removed in minutes — simple snap ring removal;


♦ Height; 3.95″
♦ Base Diameter; 3.5″
♦ Shackle Pinhole Diameter; 0.92″
♦ ProLink Assembly Weight; 0.59kg
♦ Max Cable & Synthetic Rope Diameter; 3/8″

♦ ProLink Load Rating; 16,000 pounds
♦ Ultimate Failure Load; 39,000 pounds

ProLink and FlatLink Installation

First remove your existing hook from your winch cable or synthetic rope. Using snap ring pliers, remove the snap ring and double shear pin from the ProLink/FlatLink, and insert the cable eye into the ProLink/FlatLink and reinstall the sheer pin and snap ring. Be sure that the snap ring is completely seated into the snap ring groove – that’s it, you’re done. When retracting the winch rope assembly it is advised to snug the ProLink/FlatLink up against the fairlead with some tension in the line (Keep fingers away!) This will keep the ProLink/FlatLink from coming loose and shifting on the fairlead.

About Anodized Surfaces

Anodizing is an electrochemical process that provides aluminium corrosion protection by forming a protective layer of aluminium oxide on the surface of the ProLink/FlatLink. Over time and usage, anodized aluminium surfaces will fade and scratch – that is normal wear and tear of anodized aluminium parts.

Shackle Size

The Factor55 ProLink/FlatLink is designed to be used with standard 3/4 screw pin shackles. All domestic shackles will fit the ProLink/FlatLink. Some low quality import shackles may not fit the ProLink/FlatLink – the space between the shackle legs may be too narrow to fit the ProLink/FlatLink tab. Factor 55 does not encourage the use of these low quality shackles due to the wide range of gaps between the shackle legs, as well as the uncertainty of the steel alloy composition. Always test fit your shackle to the ProLink/FlatLink prior to your off road adventure.

Always follow safe winching guidelines recommended by your winch manufacturer.
