With additional crawl and low range options limited for the
Land Cruiser enthusiasts, we decided to bring the Blackbox proven strength, low
range, and versatility to the ‘cruiser market.
We focused our efforts on the common 19 spline ‘split-case’
combination found in hundreds of thousands of Cruisers in the 40, 60 and 70
series from 1980-1989. These cruisers were built tough as nails and continue to
survive in some of the harshest conditions on earth.
Extremely versatile and capable, but one of the most
critical areas on a ‘Cruiser had major room for improvement; gearing.
Current gear offerings for the cruiser market
fall short at best; a single deeper low range, or a weak dual gearbox. We knew the multiple gear selection, compact design,
and ultimate strength of the BlackBox technology would be perfectly suited for
the application.
There were three key goals in the conception of this project
that we adhered to:
1) Shortest Possible Overall Assembled Length
2) Land Cruiser specific lower case design, no additional adapters
3) Cross Compatibility with existing BlackBox Line (more on
this below...)
Compatibility

Using our innovative transmission mount, The BlackBox-c in standard form fits the following Cruiser
transmissions and associated transfer cases
H42 4 speed manual ,19 Spline output, no extension housing
H42 4 speed manual 19 Spline output, /w Extension housing
H55 5 speed manual 19 Spline output
A440, 4 speed automatic, 19 Spline output
Cross Compatibility
The BlackBox-C has a hidden feature that some customers are
going to find extremely valuable: the ability to adapt a domestic transmission
or transfer case to a Land-cruiser transmission or transfer case using only the
BlackBox.
Since the front and rear case halves of the Blackbox are
cross compatible across the product line, we can simply mix and match BlackBox
cases to adapt different combinations, rather than buying a costly adapter that
also offers no gear reduction!
Cruiser Transmission adapted to Domestic Transfer case using
the BlackBox:
If your build includes a centered rear differential such as
Dana 60, and you want to utilize a domestic transfer case with a matching rear
output, such as a NP205, or Atlas Transfer case, but also want to retain your
Cruiser transmission, this is the solution.
This would use a BlackBox-C 19 spline front case half, with a Standard, Titan
or i series rear half depending on desired transfer case application.
Domestic Transmission adapted to Cruiser transfer case using
the BlackBox:
This is the ticket if you are re-powering your cruiser. Pop an LS and GM automatic into your FJ, and
you’re looking at a costly adapter and length that offers no additional gearing
advantages. Leverage the BlackBox’s cross
compatible design: order a standard front case half mated to a Cruiser rear
case half. Multiple advantages, one
solution.
