Product Description
Vehicle maneuverability in 4WD is often limited, but with BD Diesel’s 2Low Unloc, you can enhance it significantly. Activating the 2Low Unloc disables the front wheel drive, directing full torque to the rear wheels only, giving you the normal 2WD maneuverability in low range. This setup allows for sharp, full-lock turns without causing the front axle u-joint to hop or bind. Enjoy better control and smoother handling in tough driving conditions with BD Diesel’s 2Low Unloc system.
