FERRARI PUROSANGUE F175 Rear Left Shock Absorber

In 2026, the Rear Left Shock Absorber for the Ferrari Purosangue (F175) is one of the most technologically advanced components in the automotive world. As part of the Multimatic True Active Spool Valve (TASV) system, it is far more than a simple damper.

1. Technical Identification

• Part Number: 785515

• Position: Rear Left (LH)

• Technology: Unlike traditional “adaptive” suspensions, this is a fully active system. Each unit contains a liquid-cooled 48V brushless electric motor. This motor provides supplemental force via a ball-screw and gearbox assembly to the damper shaft, allowing it to actively “push” or “pull” the wheel to manage body roll, pitch, and heave without the need for anti-roll bars.

• Integration: It is controlled by a dedicated vehicle dynamics computer that adjusts the damping forces every 50 milliseconds.

2. 2026 Market Pricing (Estimated USD)

Because this component integrates high-voltage electronics, liquid cooling, and precision spool valves, the replacement cost is significant.

[!IMPORTANT] A complete set of four active shock absorbers for the Purosangue is currently listed at an RRP of approximately $50,000 USD in 2026.

3. Critical Installation & Maintenance

• 48V System Safety: The unit is powered by the car’s 48V secondary electrical system. Replacement requires specialized training and tools to safely de-energize the circuit before removal.

• Liquid Cooling: This shock absorber is liquid-cooled to manage the heat generated by the active motor. When replacing part 785515, the cooling circuit must be properly bled to prevent air pockets that could lead to the motor overheating and triggering a “Suspension System Failure” warning.

• Diagnostic Handshake: After installation, the unit must be calibrated using the Ferrari DEIS diagnostic tool. The car’s computer needs to recognize the new actuator to ensure the Left (785515) and Right (785516) rear units work in perfect synchrony.
