Toyota Crown Wheel And Pinion Gear

In a front-engined, rear wheel drive application the crown wheel and pinion transfers engine torque from the propshaft to the car's differential (LSD) and then onto the road wheels via the halfshafts.
It is vitally important to select the correct crown wheel and pinion ratio to suit the engine’s characteristics and the desired vehicle speed, whether for a trackday car or an outright competition machine, requiring a different set up from circuit to circuit.
