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. It eliminates the conventional winch hook and provides a precision shackle mounting hole with a thick and durable mounting tab. Engineered and machined in the USA from lightweight billet 6061 aluminum, ProLink doesn't require splicing and is compatible with steel or synthetic ropes and both hawse and roller fairleads. The cable eye is retained in the ProLink by an ultra-strong aerospace-grade titanium doubleshear pin and internal snap ring, and is easily installed in minutes. The EPDM rubber guards protects alloy fairleads and is securely attached to the ProLink with four barbed tips and prevents rattling.
