Lamborghini Aventador Huracan central locking 470601295A

The 470601295A is a high-strength, specialized central locking bolt designed for the center-lock wheel systems found on the Lamborghini Aventador and Huracán series. Unlike traditional five-lug setups, the center-lock system uses a single, large fastener to secure the wheel directly to the hub, a technology derived directly from professional motorsport to allow for faster wheel changes and reduced unsprung mass.

Technical Specifications

• Compatibility: * Lamborghini Aventador: SV (LP750-4), S (LP740-4), SVJ (LP770-4), and Ultimae models equipped with center-lock wheels.

  • Lamborghini Huracán: Performante, STO, Tecnica, and EVO models equipped with center-lock wheels.

• Material: Aerospace-grade high-tensile alloy, engineered to withstand extreme rotational forces and thermal expansion from carbon-ceramic brakes.

• Finish: Typically features a black anodized or specialized anti-friction coating to ensure consistent torque application.

• Design: Features a specific spline pattern that requires a dedicated Lamborghini center-lock socket for removal and installation.

Key Features

• Race-Derived Technology: Minimizes the rotating mass at the wheel center, improving steering response and suspension flickability.

• Safety Locking Mechanism: Designed to work with a spring-loaded locking pin within the hub that prevents the bolt from loosening under vibration or high-speed centrifugal force.

• Directional Markings: Usually includes engraved torque specifications and directional arrows to ensure proper tightening during high-pressure pit stops or service.

Technical Installation & Safety Note

The installation of the 470601295A bolt is a safety-critical procedure that requires specialized tools and strict adherence to factory protocols:

1. Torque Requirement: These bolts require a very high torque value (typically 600 Nm or approx. 442 lb-ft). A precision heavy-duty torque wrench is mandatory.

2. Lubrication: Use only the factory-specified anti-seize paste (e.g., Castrol Molub-Alloy) on the conical seat and threads. Improper lubrication will lead to incorrect torque readings and potential wheel separation.

3. Locking Pin Check: After tightening, the technician must manually verify that the central locking pin has fully engaged and is flush with the bolt surface.
