KFI Winch Contactor Replacement for ASP‑35 / AMP‑25 & Polaris HD/Pro HD Winches

OVERVIEW

The KFI Winch Contactor bridges your handheld controls and winch motor, restoring reliable switching performance in high-draw power circuits for smoother, safer operations. As a direct-fit replacement sealed contact unit, this component addresses erratic behavior resulting from worn relay internals or corroded connections. Engineered to replace failed hardware on KFI ASP‑35 and AMP‑25 platforms, it also offers verified mounting alignment for Polaris OEM HD and PRO HD winch installations.

ENGINEERING & PERFORMANCE

This assembly leverages high-grade copper windings and precision-machined contacts to maintain stable electrical flow during peak load conditions, effectively preventing voltage drops that can stall extraction attempts. Internal elements are protected by robust insulation coatings designed to repel moisture ingress and endure circuit vibration following trail impacts. The housing features exact dimensional tolerances for clean installation within existing fairlead structures, swapping out faulty hardware without the need for auxiliary brackets or structural drilling modifications.
