Ring and Pinion Gears

What Is a Ring Gear in a Differential?

A ring gear in a differential is a crucial component of the vehicle's drivetrain system. It is a large, circular gear that is attached to the differential carrier and meshes with the smaller pinion gear. Together, the ring and pinion gears work to transfer power from the driveshaft to the wheels, allowing them to rotate at different speeds when navigating turns. The ratio of the ring and pinion gears determines the vehicle's final drive ratio, impacting its performance and fuel efficiency.

What Is the Ring Gear on a Rear Differential?

The ring gear on a rear differential serves the same fundamental purpose as in any differential system. In a rear-wheel-drive vehicle, the rear differential is responsible for distributing power to the rear wheels. The ring gear, along with the pinion gear, plays a vital role in this process by transmitting torque to the rear axles, allowing the wheels to turn and propel the vehicle.

How Much Does a Ring Gear Differential Cost?

The cost of a ring gear differential can vary significantly depending on factors such as the vehicle's make and model, the type of differential, and the gear ratio. On average, you can expect to invest anywhere from a few hundred dollars to over a thousand dollars for a quality ring and pinion gear set. It's essential to choose the right gear ratio for your specific needs and consult with experts to ensure proper installation and compatibility.
