This adapter kit will couple the Toyota Truck 4wd gear-driven transfer case to be used with a R150F/ R151F 5 speed replacing the original chain-driven transfer case. The adapter kit includes an adapter plate, female 23x21 coupler oil seals, fastening hardware and adapter instructions.
The adapter assembly fits the Toyota Truck 21 spline gear driven transfer cases. This transfer case has a male 21 spline input shaft and can also be identified by 7 bolts attaching the tailhousing to the transfer case.
This kit is designed for exclusive use with the R150F / R151F 5 speed manual transmission. The 5 speeds use a 23 spline output shaft and normally used behind the 3.0 litre V6 engine (R150F) and the 1986-87 turbo 4 cylinders (R151F).
