The Trust GReddy 6-Speed Dog Transmission is the ultimate RX-7 performance gearbox for drivers demanding uncompromised strength and speed. Known in the JDM community as the definitive FD3S 6-speed dogbox, this unit replaces the fragile factory synchromesh system with a heavy-duty close-ratio dogbox design. Whether you are building a high power RX-7 drivetrain for the strip or a rotary race transmission for the circuit, the GReddy Dogbox is engineered to handle the brutal power delivery of the 13B-REW.
