The R-series transmission is much stronger than the factory equipped W59 transmissions used in 4-cylinder Tacoma’s and T100’s, and utilizes a true 23-spline transfercase. The R-series transmission features larger internal components and do not suffer from the inherent problems of the W-series transmissions, such as a weak 5 th gear, main shaft bearings, and reverse gear.

This bell housing makes for an ideal choice for all “RZ”-powered Desert Racers and Rock Crawlers alike, who desire the strongest Pickup/4Runner/T100 manual transmission and 23-spline drivetrain. Vehicles that are converted from a 3VZ-E to a 3RZ-FE will especially appreciate this bell housing due to the fact that only very minor drivetrain modifications are required.
