About Centre Locking Hubs

Centre Locking Hubs - Precision Wheel Mounting for Performance & Motorsport Applications

Centre locking hubs are high-precision wheel mounting components used on performance and motorsport vehicles to secure wheels using a single central locking nut instead of traditional multi-bolt patterns. Designed for strength, accuracy, and rapid wheel changes, centre lock systems provide superior clamping force, precise wheel alignment, and reduced unsprung weight compared with conventional wheel fixings.

Available from Design911, centre locking hubs are engineered to meet the demands of high-performance road cars, track-focused builds, and motorsport applications where reliability, safety, and precision are critical.

What Do Centre Locking Hubs Do?

Centre locking hubs form the interface between the wheel, hub assembly, and drivetrain.

Core Functions:

  • Secure the wheel using a single high-torque central nut.
  • Ensure precise wheel centring and alignment.
  • Withstand extreme loads from acceleration, braking, and cornering.
  • Reduce wheel change time in motorsport environments.
  • Support high-performance braking and suspension systems.

Their design ensures consistent wheel retention and stability under demanding driving conditions.

Why Do Centre Locking Hubs Wear or Fail?

Centre lock systems operate under significant mechanical stress and require correct installation and maintenance.

Common Causes of Wear or Failure Include:

  • Incorrect torque application during installation.
  • Repeated high load cycles from track or performance driving.
  • Wear to splines or mating surfaces over time.
  • Corrosion or contamination affecting fitment accuracy.
  • Improper tool use damaging locking interfaces.

Worn or damaged centre locking hubs can compromise wheel security, making inspection and timely replacement essential for safety.

Why Replace Centre Locking Hubs?

Replacing worn or damaged centre locking hubs restores correct wheel fitment and ensures safe operation at high speeds.

Key Benefits:

  • Maintains correct wheel retention and clamping force.
  • Restores precise wheel alignment and balance.
  • Prevents damage to wheels, hubs, and locking nuts.
  • Ensures compliance with performance and motorsport requirements.
  • Essential for safe track, race, and high-performance road use.

New centre locking hubs are critical when servicing braking systems, suspension components, or replacing wheels on centre-lock equipped vehicles.

Highlights

  • Precision-engineered centre locking wheel hubs.
  • Designed for high-performance and motorsport use.
  • Supports extreme braking and cornering loads.
  • Ensures accurate wheel centring and secure fitment.
  • Ideal for track-focused and performance road vehicles.
