Constant exposure to the elements can break down your winch line prematurely and allow abrasive grime, sand, and dirt into your winch’s gears and other moving parts. To make your winch and cable last as long as possible, use a winch cover when you are not using the winch.
For Synthetic Rope
If you run synthetic line on your winch, a cover can slow down the fading. Even with UV inhibitors, exposure to the sun will eventually fade the color on your rope. Synthetic line is designed to withstand harsh exposure to the elements, since it was originally developed for marine use, but it will last longer (and look better) if you keep it covered.
For Steel Cable
If you run steel cable, a winch cover keeps out abrasive substances and protects against rain, UV rays, and other elements. Mud, dirt, road grime, salt, sand, and ice can get into your winch gears and other winch parts and act like sandpaper, keeping your winch from running smoothly and possibly causing damage.
Even with a winch cover, it’s still important to use and maintain your winch properly if you want to get the most life out of it. There’s no substitute for taking good care of your winch with regular maintenance and cleaning.
