Lamborghini Aventador steering gear 471422061K

Part Number: 471422061K

The 471422061K is a high-performance electronic steering rack designed for the later iterations of the Lamborghini Aventador flagship series. This component is a critical part of the Lamborghini Dynamic Steering (LDS) system, specifically updated for improved tactile feedback and integration with the vehicle’s advanced chassis control systems.

Technical Specifications

• Compatibility: * Lamborghini Aventador S (LP740-4)

  • Lamborghini Aventador SVJ (LP770-4)

  • Lamborghini Aventador Ultimae

• System Type: Electronic Power Steering (EPS) with Variable Steering Ratio.

• Revision: The “K” suffix represents one of the latest technical revisions, often superseding earlier versions like “H” or “J” for improved software compatibility and internal hardware durability.

• Integration: Works in conjunction with the Lamborghini Rear-wheel Steering (LRS) to provide synchronized steering across both axles.

Key Performance Features

• Variable Ratio Logic: The LDS system modifies the steering ratio between a direct feel for track driving and a more assisted feel for low-speed maneuvers, adjusting automatically based on the selected ANIMA mode (Strada, Sport, Corsa, or Ego).

• Enhanced Feedback: The “K” revision includes refined internal dampening and motor control parameters to provide the driver with more precise communication from the front tires ($255\text{/30 ZR20}$).

• LPI 2.0 Compatibility: Fully integrates with the Lamborghini Piattaforma Inerziale (LPI) 2.0, which manages all electronic sensors in real-time to optimize the car’s dynamic behavior.

Technical Installation & Programming

Replacing an Aventador steering rack with part number 471422061K requires specific technical steps:

1. Online Parameterization: This rack must be programmed with the correct dataset for the specific model (e.g., SVJ vs. S). Without this digital “handshake,” the car’s stability control and rear-steering systems will not synchronize.

2. LRS Synchronization: Since the front and rear steering systems are linked, a “neutral position” calibration must be performed using the factory diagnostic tool to ensure the car tracks straight.

3. Torque Settings: The mounting bolts for the steering gear are one-time-use stretch bolts and must be torqued to factory specifications to ensure the rack remains secure under high lateral $G$ loads.
