| First lets take a look at the gear drive t/case.|
From 1979 to 1995, Toyota designed the mini-trucks with a very dependable gear driven
transfer case. This transfer case, model RF1A (pictured), featured a four piece design. It is this
design which separates Toyota's transfer case from the rest. With strong front output gears and an
available unbreakable 23-spline input, like
Toyota, Marlin Crawler knew for sure that this was the transfer case of choice. And since the case is
uniquely comprised of four pieces, we are easily able to obtain a lower crawl ratio.
The first piece is the reduction housing. This is where the factory reduction gears
are found. In High range, these gears are bypassed and the overall transfer case ratio is 1:1. But
when shifted into Low range, the resulting transfer case ratio then becomes 2.28:1 (stock).
