The BD Diesel 2 Low UnLoc (1030710) is a specialized performance upgrade designed for 2001–2014 GM Duramax diesel trucks equipped with LB7, LLY, LBZ, LMM, and LML engines. This innovative module allows drivers to engage low-range gearing in two-wheel drive mode, rather than being limited to four-wheel drive when using low range. This feature is especially useful for towing, maneuvering trailers, or navigating slippery conditions where full four-wheel drive isn’t necessary, helping to reduce driveline bind and front-end wear. Easy to install and built for durability, the BD Diesel 2 Low UnLoc enhances vehicle control and operational flexibility, making it a valuable addition for Duramax truck owners seeking improved drivability and utility.
