Description
Bringing the quality and craftsmanship of the original, the BlackBox-Eco was designed for the 4x4’er on a budget. While retaining the originals technology, quality and durability, the Eco is minimized to reduce cost. Designed to be a DIY builder kit; cases are shipped empty, and the customer provides the gears, and does the install and assembly. Low Range on a budget.
