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 Dana 300 we were able to reduce the overall installed length from almost 9" down to 5.33". 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.
** Note: To install a 31 Spline Input Shaft into one of our Eco Cases machining on the O.D of the Input is Required. Also a Special Pocket Bearing Adapter is required to install the proper Pocket Bearing. Please Call for more Information. **
