Close Ratio racing gearbox 2005+ Ford Mustang. Transmission has the best of everything. This gearbox has the double and triple synchros for smoother shifting. It has the close ratio, racing gearset. It also featers a shifter that bolts directly to the transmission and lands in the production shifter hole. This is an absolutely fantastic gearbox.
