When off-roading at higher speeds of say 10mph and up. When needing to make a sudden stop, your abs system can get confused and not actually help you stop.
ABS was designed to keep wheels from locking up. In the world of daily driving on pavement, this technology has helped prevent many accidents. Locked-up wheels can no longer steer the vehicle. ABS helps to keep the wheels turning so you can steer and possibly avoid colliding with something or running off the road. ABS has proven to make driving safer.
When it comes to Off-roading? Now that’s a different story. When on dirt or gravel or similar, all that loose gravel acts like little marbles and you will have very little traction between tires and ground. In this case, all 4 wheels will try to lock up but ABS will prevent this and now you won’t be able to stop quickly.
When you disable the abs, you can now push the brakes in and lock the wheels up, in turn, the tires will now dig into the dirt, gravel, etc, and quickly stop the vehicle. If you search the offroad forums this is a known issue that abs is a big no-no for off-roading especially if you are off-roading at high speeds.
