What Are Off-Road Lockers?

When off-roading, you need to be able to control how your wheels spin and the way in which they interact with the terrain. A traditional differential will spin the car wheels at different rates depending on the type of surface you are dealing with. While this is an efficient way to drive around town, it won’t be the best option when driving through mud and dirt. A locking differential, which is known as a locker, will be your best bet. An off-road locker locks the two wheels on the axle and ensures that they spin at the exact same rate. This makes it easier to traverse uneven terrain and get yourself out of tough spots with mud and water. If you are thinking of taking your vehicle’s off-roading ability up a notch, an off-road locker is a great choice.

When to Switch to a 4x4 Locker

Most of the time, a traditional differential will be sufficient for everyday driving. However, if you are thinking of doing more off-roading or you want your vehicle to be able to handle some of the toughest conditions out there, a 4x4 locker is a better choice. It will give you the ability to traverse rough trails and get yourself out of slippery terrain, which is an essential quality for serious overlanders and off-roaders.

What to Look for in an Aftermarket Locker

When choosing an aftermarket locker, think about what your expectations are. There are a few different kinds of locking differentials, including automatic, selectable, and lunchbox aftermarket lockers. You should also consider the fitment and compatibility of the component. Knowing things like your axle size and gear ratio will help you make the right choice and ensure that you can be hitting the trail without running into issues with installation. If you think it is time to make the switch to an aftermarket locker, we have everything you need.
