The Pro Circuit Shift Shaft Brace is a CNC-machined part that sits just behind the shift lever and offers added protection for the shift shaft to prevent it from bending. Since the shift shaft sticks out, it's always best to have more support and to protect the transmission from serious damage. Don't be left with a bent shift shaft and have to replace it, so pick up a Pro Circuit Shift Shaft Brace for increased protection and a factory look. Note: The plastic countershaft sprocket cover will need some custom cutting for the shift shaft brace to fit properly.
