Transmission Shafts & Gears
Transmission shafts and gear sets are the internal components that achieve gear ratio changes within the gearbox. Input shafts connect the clutch or torque converter to the internal gearing; output shafts link to the driveshaft. Performance gear sets offer alternative ratios for road racing (close ratio), off-road (wide ratio), or drag racing. Worn synchronizer rings cause grinding during downshifts and are replaced during transmission rebuilds. GBP Performance ships free across Canada.
