Differentials & backing plates

The differential is a central part of the drivetrain on rear-wheel drive and four-wheel drive cars and has a major impact on how power is transferred from the gearbox and propshaft to the wheels. The differential distributes drive between the rear wheels and also helps determine how the car behaves under acceleration, cornering, and load. That is why the differential plays an important role in normal driving, performance driving, and motorsport alike. Backing plates are a crucial part of this assembly, acting as a support structure that helps distribute load and reduce stress on other components.

For standard use, the focus is often on reliability, correct gearing, and quiet operation, but with tuning, higher power, and motorsport, greater demands are placed on strength, gearing, and the type of differential. Depending on the setup, the choice of differential can have a major impact on the car’s acceleration, traction, and handling characteristics. This is especially relevant on performance cars, race cars, drift cars, and custom builds, where the differential is often an important part of the overall setup.

At Qualitec, you will find differentials and related parts for various types of drivetrain projects. Whether you are working with a standard replacement, an upgrade for motorsport, or a more specialised project, choosing the correct differential is important for achieving a reliable and well-functioning solution.
