BD Diesel USA is a performance-oriented company specializing in high-quality diesel and heavy-duty truck components and upgrades. Their products are engineered to handle high pressure, high temperature, high load, and extended operation, not just occasional use. With years in the field (including intensive hours of idling, towing, and heavy usage), the BD Diesel's engineering and R&D is informed by real use cases.
Vehicle maneuverability is reduced while in 4WD. When the 2Low Unloc is turned on, you disable the front wheel drive mechanism allowing for full torque to be available to the rear wheels only. The front wheels will NOT be driven, delivering normal 2WD maneuverability while in low range!
This will also allow for sharp All The Way Over turns without the front axle u-joint hopping or binding.
