Bringing the quality and craftsmanship of the original, the BlackBox-Eco-i 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 Specifically for the Atlas II Transfer Cases we were able to greatly reduce the overall installed length. 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.
Replacing the input shaft and housing, the Atlas II input gear directly splines onto the EcoBox output shaft, making this a very compact 4.33” long EcoBox-i.
While the installation requires an intermediate level of mechanical aptitude, we also provide an installation overview.
