The 3/4" x 10" jackshaft with a 3/16" keyway for go-karts and mini bikes is a solid rod of steel that will handle the radial motion of the torque converter's clutch and transfer it to the drive wheel.

This jackshaft uses a milled 3/16" keyway slot that runs the entire length of the shaft, and the ends are not machined or threaded. The standard universal design means that it may be compatible with numerous other applications where a 3/4" is required.
