The main purpose of drag chains is to drag fallen trees or logs off your trail. The last thing you want is to be confronted with an immoveable fallen tree or other large obstacle in your path at the start of your off-road adventure. Fortunately, you can keep fallen trees from being a problem when you have a drag chain kit at your disposable. No 4wd owner should be without a drag chain kit if they are off-roading in treacherous conditions. They are designed to last a lifetime, given that you do not overburden the chain, making them a one-time investment that will last forever.
There are other uses for drag chain kits as well. Farm use and commercial applications make use of these chains for different purposes. However, drag chain kits are not typically recommended for winching. The reason is because the chain itself is usually not rated unless you buy a chain with a rating label every tenth link. These are very expensive options, and usually not necessary for regular 4wd applications. While the chain is not rated the shackles on the ends are. Remember, then, that these are drag chains, not extension straps for winching.
