ProLink E Expert Shackle Mount Assembly Factor 55

The Factor 55 ProLink E is a direct replacement for conventional winch hooks, engineered to give you a safer, more secure shackle attachment point at the end of your winch line. It accepts either end of a standard 3/4" screw pin shackle or up to a 1/2" soft shackle, and handles steel cable or synthetic rope up to 3/8" in diameter. Max load rating is 16,000 lbs.

Construction is precision-machined from 6061-T6 aluminum billet, hard anodized in gray, and secured with a 6Al-4V titanium 5/8" double shear pin — not a hook that can open under load. The rope or cable eye is fully captured inside the body, which is the core engineering difference that matters when a recovery goes sideways.

The integrated EPDM rubber boot protects the fairlead on both hawse and roller setups, so there's no additional hardware or adapters needed for either configuration. This thing is engineered, tested, and made in the USA — no outsourced casting, no guesswork on load ratings.

We recommend the ProLink E to anyone running a winch who hasn't already retired their factory hook. The geometry and retention design eliminate the single biggest failure point in a standard hook setup.
