Final drive Autobianchi A-112 4 and 5 speed gearbox

There are multiple reasons why you want to change your final drive. If you have an OEM final drive, you probably want to increase reliability and lifetime. If you already have a motorsport final drive, you probably want to create the perfect gearing for your car and track.
Choosing your right gearing is all about ‘compromise’. A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration.
Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.
The OEM final drives are designed for the specifications of that specific car. If you are upgrading your car, or increasing engine power, the OEM parts of the drivetrain will have a higher failure risk. Upgrading your drivetrain components is necessary.
The motorsport final drive we offer are designed and produced in France by the company SJ3P. It is specialised in transmissions parts and rely on decades off experiences. It counts highly experienced and passionnated people, SJ3P provides transmissions part for a very large range of vehicules and a very high reliability and quality.
