Lamborghini Aventador Front Shock Absorber 470412019AF

the part number 470412019AF identifies the Front Shock Absorber for the Lamborghini Aventador. This unit is a magnetorheological (MagRide) damper, part of the car’s signature pushrod suspension system.

The “AF” suffix is a specific revision typically associated with the Aventador S (LP740-4) and the Aventador SVJ (LP770-4), though it may also be used as a superseding part for earlier models to improve reliability.

1. Technical Identification

• Part Number: 470412019AF

• Type: Magnetorheological Pushrod Damper.

• Technology: Uses magnetic fluid that changes viscosity in milliseconds based on electrical input from the LDVA system, allowing for instantaneous adjustments between Strada, Sport, and Corsa modes.

• Position: Front (Generally interchangeable between Left and Right, but always verify with your specific VIN).

3. Why the “AF” Revision?

The “AF” revision represents one of the later iterations of the front shock.

• Durability Updates: Earlier versions (like the “A” or “C” revisions) were prone to leaking magnetic fluid. The “AF” version features updated internal seals designed to withstand the high pressures of track use and the “Nose Lift” system’s demands.

• Valving Calibration: It is specifically tuned to work in harmony with the Rear-Wheel Steering software, providing the necessary front-end stiffness to handle the increased cornering forces of the S and SVJ models.

4. Signs of Failure in 2026

• Hydraulic Leaks: Any sign of dark, oily residue on the shock body is a definitive failure. Magnetic fluid leaks will eventually lead to a total loss of damping.

• “Suspension System Failure” Warning: Often caused by an internal electronic short within the damper’s solenoid.

• Nose Lift Issues: Since the front shocks are part of the lifting geometry, a failing shock can sometimes cause the front lift system to act erratically or “stutter” when rising.
