Lamborghini Aventador LP750 LP770 SVJ steering gear 471422061H

Part Number: 471422061H

The 471422061H is a specialized steering rack engineered for the ultra-high-performance variants of the Aventador, specifically the LP750-4 Superveloce (SV) and the LP770-4 SVJ. This component is the primary hardware for the Lamborghini Dynamic Steering (LDS) system, which is recalibrated in these models to handle the increased downforce and lateral $G$ loads characteristic of the SV and SVJ series.

Technical Specifications

• Compatibility: Lamborghini Aventador LP750-4 SV, LP770-4 SVJ, and SVJ Roadster.

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

• Chassis Integration: Specifically tuned for models equipped with ALA (Aerodinamica Lamborghini Attiva) and rear-wheel steering (LRS).

• Revision: The “H” suffix denotes the high-performance iteration designed to withstand the higher thermal and mechanical stresses of track-focused driving.

Key Performance Features

• Variable Steering Ratio: The LDS system dynamically changes the steering ratio based on speed and the selected ANIMA mode (Strada, Sport, Corsa, or Ego), offering direct response at low speeds and high-speed stability.

• SVJ Specific Calibration: In the SVJ, this rack works in tandem with the Lamborghini Rear-wheel Steering (LRS) to provide “virtual wheelbase” shortening for agility and lengthening for stability during high-speed cornering.

   

• Heavy-Duty Construction: Features reinforced internal seals and high-torque motor assistance to manage the $350 \text{ km/h}+$ performance envelope.

Technical Installation & Compatibility

Because the 471422061H is a safety-critical and electronically complex component, it is not a “plug-and-play” part.

• Software Parameterization: This rack must be flashed with the specific datasets for the SV or SVJ chassis. Installing a standard Aventador steering rack software on this hardware will cause stability control errors.

• Calibration: After installation, a “Zero Point” calibration of the steering angle sensor and a full four-wheel alignment are mandatory to ensure the LDS and LRS systems are synchronized.
