Center lock hubs

Types of Center Lock Hubs

A center lock hub is a type of wheel hub used to attach the wheel to the axle of a vehicle. Instead of using multiple bolts or studs, it employs a single large nut in the center to secure the wheel. This design permits faster wheel changes and is often found in high-performance or racing vehicles. Center lock hubs are further divided into two main types:

• Original Equipment Manufacturer (OEM) Center Lock Hubs:

  This is a center lock hub that is already installed on a vehicle when it is bought. For instance, high-end sports cars from brands like Porsche and Ferrari use OEM center lock hubs. The hubs are designed to be compatible with the specific model of the car. They offer great performance and reliability. However, they can be costly to maintain, and spare parts are not easy to come by.
