Identifying the RF1A

You are able to identify if you have an RF1A transfer also known as the Toyota Gear Driven case by the number of bolts on the back case cover. If you have 7 bolts on the cover you have an RF1A, Gear Driven case. If you only have 5 bolts then you have a chain driven case.

Difference between Top and Forward Shift Transfer cases

The Differences between Top Shift and Forward shift is fairly self explanatory. A Top Shift RF1A will have the shifter directly on top of the reduction box and alternatively a forward shift RF1A will have shift rails extending out the front with a block off plate on top of the reduction box.

Spline Information

For stock applications the only transfer cases that used 23 spline are the 1986 and 1987 Turbo trucks and 4Runners. All other stock 1979-1995 trucks and 4Runners used the 21 spline. If you are build a dual case set up or custom application the 23 spline output shaft is stronger than the 21 spline. However it is important to know your application to be sure it will work in your attend application.
