Put Low Range Power Where You Want It

Low range is incredibly useful when you need controlled power, but traditional 4WD can make tight maneuvering feel like more work than it should. The BD Diesel 1030711 2 Low Unloc gives you another option by letting you disengage the front drive mechanism while keeping the transfer case in 4WD low range. This sends full low range power and torque to the rear wheels while restoring the familiar maneuverability of 2WD. That can make a noticeable difference when backing a trailer into a tight spot, positioning your truck around the jobsite, or making sharp turns where full 4WD is unnecessary. With the front wheels disengaged, you can turn sharply without the front axle U joints hopping or binding. An illuminated rocker switch puts control within easy reach and lets you know when the front axle override is active. Instead of choosing between low range gearing and easier steering, the 2 Low Unloc lets you take advantage of both when the situation calls for it.

Unlock Rear Wheel Torque With Low Range Control

The BD Diesel 2 Low Unloc works by manually overriding the front wheel drive mechanism while the transfer case remains in 4WD low range. Once activated, the front wheels are no longer driven through the transfer case, allowing the rear axle to receive the available low range power and torque. This arrangement maintains the high gear reduction of low range without forcing the front axle to remain engaged. Additionally, removing drive force from the front wheels helps reduce U joint hopping and binding when the steering is turned sharply. Installation is straightforward because the kit plugs in under the hood without requiring wire cutting or splicing, with an estimated installation time of approximately 90 minutes. The included illuminated rocker switch provides convenient operation while visually indicating when the front axle is being overridden. BD Diesel backs the kit with a 12 month or 12,000 mile parts warranty, and its design is legal for sale and use in all 50 states.
