Is your 4x4 roller fairlead looking old and worn? Our Nylon Rollers are the ONLY "roller" fairlead we recommend for synthetic winchrope for 4X4 winches. Because they are made from a heavy-duty nylon there can be no chafing of the winchrope as one would typically experience with aged steel rollers. The vertical rollers also have a wide center groove which helps prevent the synthetic winchrope from sliding into the corners on a side-pull. Thus preventing pinching of the winchrope.
