420 Pitch Torque Converter suit 4-stroke.

Includes 420P 10T drive sprocket.

Complete unit with everything required to fit - includes belt, drives, mounting plate, sprocket and cover.

Rear 420P 44T sprocket and a chain included!  Sprocket fits readily available standard 6-bolt go kart hub/carrier.

Expect approximately 2.7:1 initial reduction of your gear ratio upon take-off, then the torque converter will progressively move through to a final drive of approximately 0.90:1 (overdriven) at full speed.  This allows use of taller gearing on the rear without acceleration issues.
