With lightweight synthetic winch line, you get great strength and light weight, but you have to watch your winching. Abrasion can cut your winching short in a snap, so a smooth fairlead is essential. Extreme Max uses a combination of careful machining and proprietary 6-step MAGNA polishing process to create a smooth surface for perfect pulling angles. For use with synthetic winch line only. To maintain fairlead surface integrity, Extreme Max recommends installing a Hook Stopper, like our 5600.3090 Extreme Max Hook Stopper and Line Saver.
